Is lack of exposure to germs during COVID-19 weakening our immune systems?

 Since 2020, this has been the most frequently asked question referred to the IFH website. The public are concerned that reduced exposure to “harmful germs” due to social distancing and lockdowns during the COVID-19 pandemic is weakening our immune systems, fearing that once we return to a more normal lifestyle, we will be more susceptible to colds, flu and other infections.

This 2022 review summarizes current understanding of how microbes interact with the immune system. Getting the public to regard hygiene as part of healthy lifestyles which combines effective hygiene behaviours, and behaviours that reconnect with essential microbes could have a huge impact on the burden of both these diseases and the development of sustainable health.
