The immune system needs to be exposed to microorganisms for full development
According to Dr Chaitanya Challa, Senior Internal Medicine Consultant, CARE Hospital, Banjara Hills, Hyderabad (India), the immune system needs to be exposed to a certain amount of bacteria and microorganisms in the environment to perfect function. When humans are almost completely restricted from exposure to natural elements, the immune system can overreage to non-harmful substances, such as dust, pollen or animal fur. This is one of the reasons for increased allergies in communities with high hygiene levels.
An environment that is too clean reduces the body's ability to adapt
Children exposed to outdoor, soil, plants or pets are more likely to be at lower risk of allergies than children living in environmentally over-dyspieced, says Dr Chaitanya Challa. This happens because the body needs to be exposed to many different factors to form a suitable immune response.
Adults who live in closed environments, have little exposure to nature, or clean regularly with disinfectants may also experience similar conditions. When the body is not exposed to diverse microorganisms, the immune response becomes more sensitive.
The impact of modern lifestyle on the immune system
In addition to excessive hygiene, some daily habits can also reduce resistance and make the body more susceptible to allergies. Common factors include unbalanced eating, lack of exercise, prolonged stress, and irregular activities. When these habits persist, the body is more likely to lose balance, thereby making the immune response more sensitive to allergens.
How to support the immune system while maintaining hygiene
You can keep the environment clean but still help the body maintain good immunity through the following measures:
Keep hygiene at a reasonable level: Wash your hands before eating and after going to the toilet; clean necessary areas such as the kitchen and bathroom; limit the use of disinfectants too often.
Increase exposure to the natural environment: Walking outdoors, going to parks or working outdoors; Exposure to diverse environments without continuous disinfection.
Supplement foods that are good for the microbiome: Eat plenty of vegetables, fruits and whole grains; supplement fermented foods such as yogurt or similar products.
Maintain regular exercise: Physical activity improves overall health and supports the immune system.
Get enough sleep and reduce stress: Get enough sleep on time, reduce mental pressure to avoid immune decline.
If you often have sneezing, itchy eyes, nasal congestion or a prolonged rash, you should go to a medical facility for check-ups and appropriate treatment advice.
