The article, “Germaphobia! Does Our Relationship With and Knowledge of Biodiversity Affect Our Attitudes Toward Microbes?” by Jake M. Robinson et al. outlines how germaphobia, which is the pathological fear of germs, bacteria, and infectious diseases, may lead to surges in immune-related disorders. This is due to excessive sterilization and reduced exposure to biodiversity that can strengthen the human immune system. Following the COVID-19 pandemic, there has been an uptick in germaphobia, including the fear of the coronavirus as well as other viruses and bacteria. Spending time in nature and being exposed to microbes and germs is useful in promoting immune system resilience because it improves the immune system’s ability to recognize and fight off infections. Robinson encourages people to resist germaphobic attitudes and to accept the presence of germs in our environment so that we avoid 'coddling' (and thus weakening) our immune systems.

Exposing yourself to certain types of germs can help train the immune system to recognize and fight off infections, which is vital for your overall health. This is particularly important in childhood, when the immune system is still developing. Studies have shown that children who grow up in overly clean environments may be more likely to develop allergies and autoimmune diseases, likely due to the lack of exposure to diverse microbes. Although being too much of a germaphobe can be harmful for your immune system, it is important to note that excessive exposure to harmful germs can still lead to illness and disease. This is why basic hygiene practices like washing hands regularly and avoiding contact with sick individuals are still important. Therefore, it is best to find a balance between exposing yourself to too many versus too little germs in order to maintain a healthy immune system.
