Human behaviors that contribute to decreased exposure to microbes:
Method of Birthing: Vaganal births expose infants to more bacteria within the vaginal canal compared to a cesarean birth
Use of Antibiotics: Antibiotics are non-specific and target all bacteria, even the good bacteria.
Cleaning/Sanitation: Kill off bacteria in areas that people touch, thus creating less exposure to microbes.
Hand Sanitization: Soap and hand sanitizers eliminate/decreases microbe presence,
Small Social Circle: If an individual is not surrounded by many people such as siblings or people then it limits their exposure to different microbes.
Time Spent Outside: Being in the outdoors, increases the exposure to microbes, especially in dirt. Therefore, if a person doesn’t go outside much and spends more time inside, it decreases their exposure to microbes.
