How Masking Contributes to Long Covid

August 17, 2022

Alingering disorder that can last for months or years is affecting an increasing proportion of the workforce. The symptoms that contribute to Long Covid could be a result of pandemic measures and masking in particular. Increased exposure to microplastics, nanoparticles, chemicals in masks and nasopharyngeal tests parallel many of the symptoms that define Long Covid.


Surveys among thousands of people suggest 7% to 30% of people who tested positive for SARS-CoV-2 virus experienced one or more symptoms for a period longer than 12 weeks. Some people who got Covid-19 early in the pandemic still haven’t recovered. 

The syndrome Long Covid is complex as symptoms may fluctuate and people go through different stages. Symptoms have been protracted by patients at ICU and those with organ damage, but also occurred in people with only a mild infection.


A list of sixty -two different symptoms define the syndrome of Long Covid. Fatigue, brain fog, breathlessness, anxiety, depression and a loss of smell and taste are among the most frequently found symptoms.


Most scientists and medical doctors – including media – link Long Covid symptoms to the SARS-CoV-2 infection. This would be the first Coronavirus in history causing long-lasting chronic symptoms in a high percentage of the workforce. People with Long Covid can experience social isolation and stigma because of their inability to perform. The rise of Long Covid has created millions of new people with disabilities.


The root cause of the disease is still mysterious. In several case studies and an excellent study published in the Annals of Internal Medicine that investigated many diagnostic parameters in people with and without Long Covid, no biological change could explain a link to Long Covid. Some scientists relate the symptoms of Long Covid to other complex diseases of multidisciplinary origin like Alzheimer’s disease, Lyme disease, Fibromyalgia, Chronic Fatigue Syndrome or hyperventilation syndrome


Many countries have started special clinics and funded research especially for studying lingering effects. A one-sizefits-all successful treatment has not been found yet. Thousands or maybe over a hundred million are frustrated at the lack of treatment available. Doctors and scientists prefer a holistic approach, but medical and social services are often understaffed. 


Desperate patients with Long Covid symptoms are traveling abroad to private clinics for blood apheresis and the prescription of anti-coagulation drugs, though treatments are still experimental and evidence on effectiveness is still lacking. For some patients these treatments have been successful, for others not.


Covid-19 vaccination has been a hot topic in speeches of politicians and advertising in the media as a motivation for preventing Long Covid. However, a large study among 13 million people published in Nature Medicine could only demonstrate a small effect. 

A study published in the Italian Journal of Pediatrics demonstrated that physical symptoms were restored much faster as compared to mental symptoms, suggesting Long Covid could be related to pandemic measures rather than a viral infection. The risks for Long Covid symptoms have shown to be increased for people with existing chronic diseases, increasing age, and lower income, women being more susceptible than men. 


Fear, social isolation, depression and worries for education and decreased income are thought to be related to the symptoms of Long Covid in children with and without a positive PCR test. As the emergency of the pandemic continues a worrying spike in chronic diseasessuicide and excess mortality are noticed at the global level. This indicates the deprivation of a resilient immune system with an increased susceptibility for lingering symptoms of Long Covid.


Symptoms Long Covid link to MIES


At this point there has been limited attention for a possible relation of Long Covid and exposure to chemicals in masks, nasopharyngeal tests and disinfectants. In a meta-analysis by an interdisciplinary team of German physicians, a potential risk of Mask Induced Exhaustion Syndrome (MIES) has been found. The most frequently observed symptoms (fatigue, headaches, dizziness, lack of concentration) as described for MIES overlap with important symptoms for Long Covid syndrome. 


The lack of smell and taste during Covid-19 seems to be different as compared to symptoms during the flu. A lack of taste and smell are frequently observed after chemotherapy in cancer treatments and has been linked to malnutrition, inflammation and depression. Also, brain fog is a symptom occurring after chemotherapy. It seems likely that harmful effects by long-term mask-wearing and frequent nasopharyngeal testing with increased exposure to chemicals (not naturally found products) can accelerate symptoms and contribute to Long Covid.


Up to now, the safety of long-term and frequent wearing of masks and taking nasal swab samples in a delicate area in the nose, often by hardly experienced persons, have been poorly investigated. Severe nose bleedings (epistaxis), cerebrospinal fluid leakage , vomiting, dizziness and fainting have been reported. Most frequently used masks and nasopharyngeal tests are derived from China with less strict controls and measures for the presence of hazardous materials. 


In several countries masks and nasopharyngeal tests delivered by governments were taken from the marketMicroplastics, nanoparticles (graphene oxide, titanium dioxide, silver, ethylene oxide, coloring compounds, fluorocarbon (PFAS) and heavy metals have been found in masks and nasopharyngeal tests. Unfortunately, not all masks and tests used during the pandemic are controlled. A report from the Dutch Public Health institute (RIVM) released in November 2021 stated “the safety of masks cannot be guaranteed.” 


The short- and long-term impact of frequent exposure on the physiology and physical and mental functioning of the human body is unknown. Harmful effects for children, who are less able to detoxify, could result in a compromised immune and nervous system resulting in repeated and rare infections with more chronic diseases during aging and less healthy future generations. 

Microplastics and nanoparticles withdraw proteins, vitamins and minerals forming bio- corona (microclots), accumulating in important organs (blood, liver, gut, lung tissue), and disturb important physiological and immunological processes

The liver, lungs and gut are important organs in energy metabolism, detoxification and surveillance by the innate immune system. Disrupting a delicate gut-liver-brain axis can relate to fatigue and exhaustion. 


Seeking more answers for a Long Covid mystery


The Belgium Public Health Institute, Sciensano, found titanium dioxide in 24 types of masks. A recent publication in Gut showed that exposure to titanium dioxide could exacerbate inflammation of the colon (Colitis Ulcerosa) weakening the innate immune system. Furthermore, titanium dioxide can enter directly into the brain and cause oxidative stress in glial cells (or mast cells), cells with an important role in the proper functioning of the innate immune system and nervous system. Maternal exposure to titanium dioxide during pregnancy may result in impaired memory in the infant. Long-term exposure and high concentrations could even cause DNA damage. Unfortunately, masks with titanium dioxide are still available on the market. 

Mental problems, anxiety and depression, have been linked to a change in the microbiome. Researchers from Stanford University observed in patients with gut inflammation (Crohn’s disease, irritable bowel syndrome, Colitis Ulcerosa) a link to missing gut microbes as compared to healthy persons. A significantly increased risk of a new onset of psychiatric illness is concentrated in the early post-acute phase of a Covid-19 infection. 


A team of Japanese scientists discovered the presence of pathogens (bacteria and fungi) on the inner and outer side of various masks. In case of a disrupted growth of pathogenic bacteria and fungi the body is exposed to a higher concentration of (myco)toxins that often leads to feeling fatigue and sickness.


Overgrowth of facultative anaerobe bacteria (bacteria needing less oxygen) for example methicillin-resistant Staphylococcus aureus has been related to mask acne and mask mouth. Staphylococcus aureus may cause pneumonia, sepsis and blood poisoning. Many of the exotoxins and secreted enzymes secreted by these bacteria suppress the T cell repertoire of the immune system. The excreted products can also cause aggregation of phagocytes, decreasing phagocytosis resulting in an impaired innate and adaptive immune system. 


A long-term albeit small change in the O2/CO2 gases in the inhaled air may influence an unfavorable change in the microbiome on the skin, mouth, nose, lungs and gut. Both oxygen and carbon dioxide are the primary gaseous substrate and product respectively, of oxidative metabolism in each cell. Variations in the levels of these gases outside the physiological range can lead to pathological conditions including respiratory and heart problems, permanent injury, immune suppression, increased aging, and altered gene expression for fertility and death. Carbon dioxide poisoning is recognized as an often-forgotten cause of intoxication in the emergency department. Several studies found an Increased level of carbon dioxide when wearing masks. This phenomenon was more pronounced during sports


The laboratory of a South Africa scientist has found significant microclot formation in Long Covid patients and acute Covid patients. Acute Covid-19 is not only a lung disease but affects the vascular and coagulation system. Unfortunately, inflammatory molecules are missed in normal blood tests as they are entrapped in the fibrinolytic resistant microclots. The presence of the microclots and hyperactivated platelets perpetuates coagulation and vascular pathology, resulting in cells not getting enough oxygen. Oxygen deprivation damages every single organ. Many Covid patients have low oxygen in the blood and are treated with oxygen therapy. 

 Oxygen deprivation at the cellular level is also described for bio-corona that are formed in the human body when exposed to graphene-oxide and microplastics. Graphene-oxide and microplastics are found in masks and nasopharyngeal swabs and may enter the human body via airways, eyes or food.


Two and a half years into the pandemic the immune system is disrupted by O2 deprivation and exposure to microplastics, nanoparticles and other toxic chemicals. This leads to an unfavorable change in the microbiome, brain damage, inflammation and the formation of microclots. Microclots could be amyloids formed by excreted bacterial products and/or biocorona, formed by nanoparticle and microplastics. The microclots cannot naturally break down by fibrinolysis and accelerates O2 deprivation in capillaries and at the cellular level. 


Wearing masks and nasopharyngeal swabs could lead to (sudden) death


The results of Foegen’s observational study published in Medicine strongly suggest that mask mandates caused 50% more deaths compared to no mask mandates. Dr Foegen theorized that hyper-condensed droplets caught by masks are reinhaled and introduced deeper into the respiratory tract responsible for higher viral loads and an increased mortality rate (The Foegen effect). Exposure to microplastics may result in lung fibrosis.


Also, a peer-reviewed study published in April 2022 on mask usage across Europe noted a moderate positive correlation between mask usage and deaths in Western Europe. 


Not harm, supporting lives is the purpose of life


The policy of politicians and advisory experts promoting a reintroduction of pandemic measures is a high risk for a disastrous effect for a now chemically poisoned population with a weakened immune system


In many countries in the world excessive mortality and sickness is observed. Each of the measures including Covid-19 vaccination might have their own contribution to the weakened immune system.


The observed microclots in patients with Long Covid and acute Covid, independent of Covid-19 vaccination, is indicating that any measure that may cause oxygen deprivation or inflammation is a risk for sudden death, and more severe infectious and chronic diseases (liver, heart problems and neurodegenerative diseases). At this moment it is not known which concentration of microclots and oxygen deprivation may result in severe symptoms or even death.


Above all, after two and a half years into the pandemic, neglecting the basic principles of Public Health, the pandemic measures do not show benefits in reduction of Covid-19 infection and Covid-19 deaths. The policy of mask-wearing and frequent testing is ineffective, expensive, and causes harm to humanity and the environment. Therefore, mask-wearing and frequent testing should be halted immediately worldwide.


The priority need is a political will and governmental funding to focus on strengthening the immune system, preventing malnutrition and famine for all. Moreover, millions of individuals suffering from Long Covid, or side effects of Covid-19 vaccines have the right for personal and financial support. Otherwise many people may become disabled as a result of poor management of this crisis.

As women used to live longer than men even during severe famines and epidemics, a continued post-pandemic increase in female mortality and disabilities can’t stay hidden or neglected. During the Covid pandemic in many High-Income Countries, injuries, disabilities, and all-cause mortality started to rise above expectations. In 2020, the gender gap in mortality widened due to an observed increased mortality in men. While in 2021 male health seemed to bounce back to earlier trends, mortality and disabilities in women continue to rise above earlier trends and are not expected to solve themselves soon. This might cause a fundamental and permanent change in the dynamics of the gender mortality gap. Recent decisions on austerity measures for budgets on female health and welfare will exacerbate this hidden disaster. Instead, Public Health Experts and CEOs of insurance companies need to take their moral responsibility and turn to smart investments in female health, addressing all gender disparities, to reverse a downward spiral in global population health. A Sudden Rise in Excess Mortality and Disabilities In September 2024, Swiss Re published in their annual report, “Many countries worldwide still report elevated death in their population today.” This impact appears independent of healthcare system or population health. In the pessimistic model, Swiss Re would expect excess deaths to continue for another decade. There is also likely a degree of excess mortality underreporting. CFOs from other life insurance companies confirmed that experienced mortality rates are broadly in line with this report. A skyrocketing increase in disability claimants since 2020 is another puzzling factor why CEOs of insurance companies are facing major problems with their financial model. The growth in demand is much lower, and the number of people making claims is much higher than expected. Declining revenues may soon hit the corporate bottom line. For the first time in 80 years, the stocks from insurer Centene Medicaid plummeted in July 2025 by 41% after the insurer had to withdraw its full financial guidance because previous estimates were way off. The analysis from insurance companies is comparable with earlier reports from Phinance Technologies , which analyzed publicly available data from the US and UK using various methods. Other independent analysts observed similar trends. In recent years, hundreds of peer – reviewed articles discuss excess mortality and adverse events of special interest in various countries of pandemic measurements and after Covid-19 vaccinations. Boston University just published the all-cause mortality in the US as compared to other High-Income Countries and showed that excess death rates peaked in 2021 and declined in 2022 and 2023 but remained substantially higher than pre-pandemic rates, especially in the age group 25-44 years. Mortality among US adults aged 25-44 years was 2.6 times higher as compared to other High-Income Countries. A recent opinion from Kakeya et al. describes a significant increase in excess deaths after repeated Covid-19 vaccinations. Japan is the country with the highest per capita rate of messenger ribonucleic acid mRNA vaccination doses in the world. A systematic review on Covid-19 mechanisms of injury and death compiled with autopsy confirmation by a physician application suggests there is a likelihood of a causal link between Covid-19 vaccines and deaths. While there are studies that conclude there is no significant increase in stillbirths when women were vaccinated with the Covid-19 mRNA vaccine during pregnancy, a study based on VAERS data shows a significant increase. Another, not yet peer-reviewed, study indicates that Covid-19 vaccination with dose 1 during weeks 8-13 of pregnancy was associated with 3.9 fetal losses above expected for every 100 exposed pregnancies. A study in the Czech Republic on live births of vaccinated versus non-vaccinated women demonstrated a substantially lower successful conception rate among vaccinated women than for those who were not vaccinated. The fertility rate in the Czech Republic dropped from 1.85 births per 1,000 women in 2021 to 1.62 in 2022 and 1.45 in 2023. Births in the EU fell to 1.38 births per woman. Also the US reported a historically low birth rate in 2023. Many Western countries are facing a similar problem with dropping fertility rates as the health of young women declined during the pandemic and post-pandemic economic instability. Furthermore, maternal mortality rates accelerated at an alarming rate, especially from 2019-2022 in the US and UK, mainly caused by cardiovascular problems. The sharp spike in maternal death could not be explained by older age. Pregnancy-related maternal deaths are getting worse. In the UK, suicide remains the leading cause of direct maternal death in the first postnatal year. Pandemic measures resulted in a collapse of women’s health and income, especially for those with the lowest wages working in healthcare, social services, education, and retail. During this period, the number of female healthcare worker suicides and fatal overdoses increased . ‘When the health of those who look out for people’s health is at risk the whole population and economy are at risk.’ Furthermore, it is well known that women respond more strongly and may experience a higher risk for complications after vaccinations. An age and sex associated difference in immune cell population might explain this. Observations from vaccination trials in Guinea-Bissau suggest increased female-male mortality ratio associated with inactivated polio and diphtheria-tetanus-pertussis vaccine. There is precedent for the observation that infant girls experience increased mortality following receipt of vaccines. People in healthcare (80% women) have been recommended and sometimes mandated a yearly flu vaccine and several boosters with Covid vaccine. While not tested, a flu vaccine and Covid vaccine were mostly given at the same moment. A recent British study among 1,745 healthcare workers showed booster vaccinations did not contribute to the protection of the healthcare workforce in a post-pandemic setting. The Covid-19 vaccination may even temporarily increase the likelihood of symptomatic infection and workday loss. A study of a large cohort of 3805 healthcare workers in Sweden confirmed that adverse reactions after Covid 19 vaccination can lead to a substantial amount of missed work shifts that can cause organizational disturbances in staffing. Risks were found to differ by vaccine type and regimen used, age, and sex, with young female healthcare workers experiencing more adverse reactions. The recently published British and Swedish studies are in line with a few earlier studies. Recommending a combined use of four vaccines that prior to use had not been tested together during pregnancy when the immune system is following a precious time clock for the survival of both mother and child has been a risky approach. Clinical trials with the Covid mRNA vaccine during pregnancy have shown data with serious worries that should have been openly discussed with pregnant women. Moreover, long-term effects for both mother and child remain unknown. After the Netherlands and the UK, the US only recently said that Covid-19 vaccines are no longer recommended for healthy people under the age of 65 years and pregnant women. Whereas Covid-19 vaccines are still recommended for immunocompromised people, unfortunately they might be more at risk for experiencing Covid-19 infections after booster immunizations. Although a causal relation remains difficult, the effects of repeated mRNA vaccination in combination or shortly before or after other vaccinations and/or using (psychiatric) medicine need to be elucidated. Sex differences in cost-effective harm analysis will help future decision -making. Last week Robert F Kennedy, Jr stopped financing 500 million subsidiaries for the mRNA vaccine platform. Also the director of the NIH Dr Jay Bhattacharya wrote an opinion piece for the Washington Post: “Why the NIH is pivoting away from mRNA vaccines.” As a vaccine for a broad public use mRNA technology has failed to earn public trust. A Post-Pandemic Increase of Female Mortality In nearly all populations, women live longer than men. The ubiquity of female survival advantage for all ages, even during famine or epidemics, when mortality is extraordinarily high is changing. Unfortunately, there is limited information available on sex differences in excess mortality from major respiratory infectious diseases. A peer-reviewed study on the first wave of the Covid-19 pandemic in Italy observed that gender differences in excess risk of death existed, but with a nuanced and non-consistent picture. The general finding of this study is that males up to 75 have been suffering more excess deaths as compared to females. However, this picture is less clear-cut at older ages when more women are living in nursing homes which during the Covid pandemic showed the highest mortality rates. A study from the Netherlands on sex differences in Covid-19 mortalities skipped the data from healthcare workers and people living in nursing homes (mostly females) to confirm that male sex is a predisposing factor for severe Covid-19 independent of age and comorbidities. Some other studies and a recent study (preprint) suggest Covid-19 did not produce lasting shifts in pre-pandemic sex differences in mortality in High-Income Countries and did not change the fundamental dynamic of the sex mortality gap. The authors observed that the male disadvantage in the Covid-19 mortality based on absolute death counts was concentrated in the pre-vaccine phase and declined over time. Relative increases in mortality were often similar between sexes, and in some cases, greater among women. Another study on excess mortality of 561 regions and 21 countries in Europe indicate that in many European regions, where drops in life expectancy were more moderate, more pronounced life expectancy losses were found for women. The authors suggest that the degree of mortality deterioration is not necessarily linked to biological sex. A cohort study of the overall impact of the Covid-19 pandemic on mortality in France observed four consecutive years of excess mortality and a growing impact on people from 20-60s, particularly men. Unfortunately, no peer-reviewed publications on sex differences and excess mortality cover the years 2024-2025. Yet, during the International Conference of Actuaries in 2025 Nationale Nederlanden, a Dutch insurance company, presented a continued rise in female excess mortality in the Dutch population from 2024-2025, while male excess mortality tended to decline. Furthermore, analysis showed a much higher degree of female excess mortality as compared to EU countries in general, while the Dutch male population experienced a better life expectancy as compared to EU countries.

Many countries now face a growing problem with an aging population and declining childbirths. Too many infants still die unnecessarily before the age of five years. Countries increasingly struggle to keep their economies stable. While Public Health experts communicate to focus on healthier future generations, declining health in young females is ignored. The healthiest generation with a flourishing economy is achieved by a holistic strategy addressing Young Women’s Health as a Public Health priority. The Healthiest Generation of the World in 2040 A Federation of Organizations involved in Public Health in the Netherlands has the ambition to reach the healthiest generation of the world in 2040 . Health is aimed at all levels; mental, social, and physical. To achieve this goal, the Netherlands needs the healthiest young females of the world. In contrast, data analysis from the Netherlands shows the opposite; the health of young women is declining fast. In other Western countries, it won’t be much better. The health of young women has worsened worldwide; it is time to face reality. Women’s bodily functioning and metabolism differ from men and need specific female-adapted health support. While many health problems in a population could be prevented when young females are supported for optimal health prior to pregnancy, this is not a priority of Public Health Agencies. Good health for the next generation starts with a strong and resilient immune system before pregnancy and during the first 1,000 days around pregnancy, birth, and postpartum breastfeeding. Childbirth and children’s health are declining; the number of women dying during pregnancy (within 42 days after labor) is increasing, as well as the number of abortions. Without change, these conflicting trends may develop into a disaster touching all levels of society. The Public Health Future Outlook of the Netherlands predicts that close to 12 million people will have a chronic condition by 2050. Young Women’s Health Is Declining Around half of the young people aged 6-25 years in the Netherlands experience mental health problems. Moreover, 47% of the people aged 15-44 years are diagnosed with at least one chronic disease, with young women more often diagnosed than men. When diagnosed with a chronic disease, people work less, experience more sick leaves, and are less productive. Unfortunately, not being able to work contributes to poorer health and income. An even larger percentage of young people (79%) still suffer from a negative impact of the pandemic, with women and lower-educated individuals hit hardest and experiencing mental problems like emotional exhaustion, stress, and hyperactivity. A recent study published in PNAS showed a faster aging of the brains of young females as compared to young males, which might be related to chronic stress exposure. Students experience more stress than before due to worries about inflation and the high costs of living. Within the EU, the Netherlands has grown into the most expensive country to live in. Unfortunately, there is much more that is troubling the health of young females. Increased Drug Use and a Dangerous Beauty Myth During the pandemic, the use of antidepressants increased by 16% for those aged 16-24 years and for children. Women are prescribed antidepressants earlier and take them twice as much as men. While the positive effects of SSRI have been criticized repeatedly and women report more side effects than men, these medicines are still frequently prescribed by medical doctors. One in four young people in the Netherlands use Ritalin or Concerta ( methylphenidate ) without a medical prescription to improve concentration and study results. Most people are unaware of the potential risks, like sudden death, that are well-known as a potential side effect. Research has shown that 5.5-22.5% of the young have used ADHD medication without a doctor’s prescription. Furthermore, in mid-2023, a worrisome increase in NSAID like paracetamol (Tylenol or Acetaminophen) and ibuprofen use was observed, especially in young girls, increasing the risk for poisoning. The use of antibiotics like amoxicillin increased for children 0-10 years (55%) and for those aged 11-20 years with 50%. As 2023 was the first year after the pandemic with all festivals open to the public, an increased use of party drugs (like ecstasy ) among those aged 16-35 years was noticed with regularly registered symptoms of poisoning. The online and interconnected world exposes the risk of cyberbullying among young people. Ironically, many are feeling lonelier than ever before and are struggling with their weight and self-confidence, setting them up for poor health as adults. The beauty myth is another danger. During the years 2019-2022, the use of fillers increased by 80%, and the use of Botox doubled among young women. Exposure to microplastics, nanoplastics, and nanoparticles has increased. Furthermore, the concentration of PFAS/PFOA in Dutch drinking water is found to be above the norm and may decrease the fertility of both women and men. On the other hand, the use of oral hormonal contraceptives by young girls diminished in the Netherlands, with only a slight increase in the use of an intrauterine hormonal device. Recent studies showed that there is an increased risk, although small, of myocardial infarction or stroke when using hormonal contraceptives. The use of an intrauterine device with levonorgestrel did not show the risk. Given the extensive and ongoing reliance of millions of young women on these drugs, ensuring their safety remains a critical responsibility of the medical community. As well as medical doctors informing young women of potential harm based on the latest scientific literature by informed consent. Over the past 4 years, girls and young women have been exposed to repeated HPV vaccinations and Covid-19 mRNA vaccines within a short period of time, for both of which side effects in women have been reported to be more frequent and severe. Possible interactions and/or interference with these vaccines and long-term effects on the immune system and microbiome have not been investigated beforehand. Neither was knowledge available when it started in 2021 on the possible risks and short- and long-term effects when four vaccines before 22 weeks of pregnancy were introduced. Nutritious Food Not Affordable for Many The importance of daily consumption, as recommended by the WHO, of 400 grams of fresh fruit and vegetables, meat, milk products, and eggs for a healthy life and joyful social and working life is unknown by many young people. For most of them, it has become unaffordable . (Ultra)processed foods are the cheapest satisfying foods with a well-designed composition of low-cost ingredients, sugar, fat, and salt that change the microbiome. Home, school, commercials, social media, influencers, mobile phones, and retail environments are driving obesity and being overweight in children and adolescents, often concurrent with undernutrition and anemia. A growing body of evidence shows that the billions of microorganisms present in our body are intimately involved in weight gain and loss and immune training and modulation, as well as overall host homeostasis. Around 33% of the population in the Netherlands does not consume fruit and vegetables daily. As of 2024, 7.1% of Dutch children live in poverty, and this number is still growing . More children might be undernourished, which is associated with impaired growth, neurodevelopment, and increased infectious morbidity and mortality. To reverse the problem of malnutrition, the delivery of free meals has recently started at primary schools. Unfortunately, this does not make a difference for the children at secondary schools. While sending funding to developing countries to prevent malnutrition, a similar problem appears in front of our eyes in the Netherlands. The young generation predominantly eats more plant-based foods, as it would improve climate change. Almost 30% of young women prefer to shop for vegetarian food, and 0.7% of the Dutch population is vegan. In addition, the EU introduced novel food products such as insects and worms, lab-grown meat, and Bovaer for cows to reduce methane production, which might affect the human immune system. Almost one in five adolescents vape. Long-term effects are yet unknown. In the Netherlands, vapes with synthetic liquids that taste like cola, vanilla, apricot, etc., have now been forbidden . Although smoking is declining in adults, young women more frequently smoke than boys but drink less alcohol. All internal and external environmental factors may contribute to weakening or strengthening the resilience of the immune system and may therefore influence the period of pregnancy, labor, nursing, and the health of mother and child for future generations. Pregnancy Is Regulated by a Unique Complexity of the Immune System Pregnancy is a unique immunological state. The changes of the immune system in the three stages of pregnancy (very early, mid, and late stage) are meticulously timed. In the very early stage, the immune system adjusts to prevent her body from rejecting the fetus while at the same time still being strong enough to keep out foreign pathogens. In the late stage, the body is preparing for labor, which is driven by an inflammatory response. A full-term pregnancy will follow an immunological clock . Changes in this immune profile could help to predict and possibly prevent preterm labor. Studies show that pathologically-driven inflammation might trigger pre-term birth (before 37 weeks). In the Netherlands, 14.8% of the children born are preterm with 9.7% low birth weight for the duration of the pregnancy (Big2). Interestingly, in the case of a preterm child labor, the inflammatory reaction is more heated as compared to a full-term child labor. Preterm birth is an important indicator of a risk for early death, chronic and infectious diseases, sepsis, stunting, and delayed neurological and brain development. This may manifest throughout one’s lifespan. Very early birth and extreme early birth occur in only 1.5% of the Dutch baby population and are responsible for 50% of the deaths of newborn babies. The number of abortions jumped in two years in 2023 to 39,000, with most by women aged 25-34 years of age. Abortion in the Netherlands is allowed until 24 weeks of pregnancy. The number of childbirths has declined dramatically to 167,504 in 2022. That is 1.49 children per woman, with a mean age of 30.3 years. The number of women breast-feeding is also decreasing. At 6 months, women feeding breast milk lowered from 60% to hardly 30% of the young mothers. Each year, around 661 babies in the Netherlands die. Mothers dying within 42 days after labor are around 11 persons a year with an additional 5 women dying by suicide each year, and not counting women who died from cancer. Over the past years, mothers’ deaths have been increasing worldwide, with the leading cause being heart diseases and blood clots. Pregnant women with stress , depression , or anxiety , as well as obese women with gut inflammation and chronic disease, have altered immune systems and, as a consequence of malnutrition, have an altered microbiome. A weakened immune system suggests an increased risk for preeclampsia, high blood pressure, HELLP syndrome, gestational diabetes, preterm labor, and/or low birth weight. ‘Gut Feeling’ a Turmoil for Healthy Future Generations The gut presents 70-80% of the immune cells in the human body. In the mucosal layer of the intestine, neuronal cells, endocrine cells, and immune cells cooperate to manage its metabolism and bodily functioning. Recent studies in mice showed villi of the mucosal layer expanding twice its volume during pregnancy and breastfeeding, slowing food passage, improving digestion for an optimal use of available nutrition. The intestinal mucosal layer is strongly connected to various stages of pregnancy with altered gut microbiota, metabolites, and cytokines. These bioactive metabolites modulate and change the ‘innate’ and ‘adaptive’ immune system. Together, the microbial composition and the mucosal layer of the intestine determine long-term health. Mothers’ intestines influence the biodiversity of the microbiome and the resilience of the immune system, which is transmitted to the baby during pregnancy, labor, and nursing. Earlier periods in life facing hunger, extreme stress, or severe diseases may influence health during pregnancy and may transmit to the baby throughout one’s lifespan and even with intergenerational effects. Specific nutrients may have positive effects during pregnancy, labor, and nursing. Sufficient vitamin D , present in sunlight, nutrition (fish, milk products), or supplements, is a prerequisite during this precious time in life for both mother and child. For young women who wish to become pregnant, it is important to learn how to balance the immune system and the microbiome. The immune system of young women could be the most important regulator of the healthiest generations and a population’s workability and income. Author: dr.
