Hygiene Hypothesis
The Hygiene Hypothesis states that an overexposure to too-clean environments may adversely affect the immune system, leading to a higher rate of allergies, asthma and autoimmune diseases. This suggests that exposure to certain types of bacteria and other microorganisms in our environment may help decrease the risk of developing allergies and other immune-related issues. This hypothesis has been supported by a number of epidemiological studies, demonstrating a link between lower levels of dirt and dust, and a higher prevalence of allergic and autoimmune diseases. The Hygiene Hypothesis has important implications for public health and the design of our living spaces and the products we use for cleaning, as well as our diet and lifestyle.
