since the coronavirus pandemic, awareness of hygiene has increased. However, bacteria and other microbes are also important, especially for children. Exposure to microbes, including bacteria, fungi, and single-cell organisms, is crucial for building a healthy immune system. This exposure may even help reduce the risk of asthma and allergies.

Their bodies react exaggerated when these allergies come to look around, and the chance of asthma then increases.
City vs.Countryside
Research in the last century revealed differences in allergy rates between populations living in rural versus urban environments. One hypothesis suggested that children from rural areas are more resilient due to their exposure to animals and nature, where various microbes are present.
One study in the Netherlands investigated whether microbes have a positive effect on children’s resilience on Dutch farms. The results indicated a positive correlation.
According to researchers, Asthma is a hypersensitive reaction of the immune system to harmless substances. It is indeed thus crucial to expose the immune system to certain substances to reduce the risk of asthma. The microorganisms on farms and in stables ensure that children react less intensely to viruses.
While it’s not definitively known if city children get sick more often than those in the countryside, differences in asthma cases based on location have been observed. In some urban environments, the immune system may be less trained and less familiar with harmless substances like bacteria and fungi, potentially leading the body to perceive them as allergens. this overreaction can increase the likelihood of allergies.
It’s important to note that asthma can also be innate and hereditary. Therefore, prevention isn’t always possible, and not all children with asthma have had insufficient outdoor play.

Not mopping every day isn’t necessarily bad; in fact,it can be good for your child’s health.
Hygiene Considerations
While maintaining a clean home is desirable, experts suggest that excessive focus on cleanliness may not be necessary for a child’s protection. According to an immunology professor, Not mopping every day isn’t necessarily bad; in fact, it can be good for your child’s health. The immune system receives stimuli and is thus trained, leading to a less violent reaction in the future.

Tips to Improve a Child’s Resistance
Small adjustments to daily routines can improve a child’s resistance. Encourage outdoor play and don’t be overly concerned if children get dirty. Allowing them to put their fingers in their mouths occasionally isn’t necessarily harmful and can benefit their immune system.
Exposure to new substances trains the immune system, leading to a less intense reaction to bacteria and fungi in the future.
While it’s still important to wash hands upon returning home, remember that exposure doesn’t always require a forest.A park or even a green space in the neighborhood can be sufficient.
In short: Sometimes you have to get dirty to be clean again later.
The Importance of Microbes for Children’s Immunity
In the wake of increased hygiene awareness since the coronavirus pandemic,it’s crucial to understand the vital role microbes play in children’s health. exposure to various microbes, including bacteria and fungi, can be key to building a strong immune system.
Frequently Asked Questions About Children’s Immunity
Why are Microbes Vital for Children’s Immunity?
Exposure to microbes, such as bacteria, fungi, and single-cell organisms, is crucial for building a healthy immune system in children. This exposure can help reduce the risk of allergies and asthma.
How Does Exposure to Microbes Benefit Children?
The immune system learns to differentiate between harmful and harmless substances through exposure to microbes. This “training” can prevent the immune system from overreacting to harmless substances, thus reducing the likelihood of allergies and asthma. An immunology professor at Leiden UMC explains, “Their bodies react exaggerated when these allergies come to look around, and the chance of asthma then increases.”
What is the Hygiene hypothesis?
the hygiene hypothesis suggests that reduced exposure to microbes in early childhood may increase the risk of allergies and autoimmune diseases. This is because the immune system doesn’t get the necessary training to distinguish between harmful and harmless substances.
What is the Difference Between City and Countryside Environments for children’s Immunity?
Research suggests that children in rural areas, wiht greater exposure to animals and nature’s diverse microbes, often have lower rates of allergies compared to those in urban environments. In some urban settings, the immune system may not be as well-trained, leading to an overreaction to harmless substances.
Do Children Get Sick More Often in the Countryside?
It’s not definitively known if city children get sick more often than those in the countryside, although differences in asthma cases based on location have been observed.
Is Excessive Cleanliness Harmful to Children’s Health?
Experts suggest that excessive focus on cleanliness may not be necessary for a child’s protection. An immunology professor states, “Not mopping every day isn’t necessarily bad; actually, it can be good for your child’s health. The immune system receives stimuli and is thus trained, leading to a less violent reaction in the future.”
What are some Practical Tips to improve a Child’s Resistance?
- Encourage Outdoor Play: Allow children to play outside in parks, green spaces, or even in the dirt.
- Don’t Overreact to Dirt: Getting dirty is a natural part of childhood and can benefit the immune system.
- Occasional Finger-Sucking: Allowing children to put their fingers in their mouths occasionally is not necessarily harmful and may help build their immune system.
- Handwashing: Make sure your child washes the hands when returning home.
What are the potential Risks of limited Exposure to Microbes?
Limited exposure to microbes early in life may lead to an immune system that overreacts to harmless substances, increasing the risk of allergies and asthma. Without proper training, the immune system may mistakenly identify everyday substances as threats.
Summary Table
| Factor | impact on Immunity | Examples |
|---|---|---|
| Microbial Exposure | Trains the immune system, reduces overreaction | Bacteria, fungi, contact with nature |
| Excessive Cleanliness | May hinder immune system progress | Overuse of sanitizers, limited outdoor play |
| Environment (Countryside vs. City) | Rural areas may offer greater microbial diversity, potentially reducing allergy risk | Exposure to animals and natural environments |
providing children with opportunities to interact with the natural environment and diverse microbes is a crucial aspect of building a robust immune system. Finding a balance between cleanliness and exposure can play a meaningful role in reducing the risk of allergies and asthma, paving the way for a healthier future.
