The feeling of disgust could lower your risk for disease.
Your body may be onto something when it triggers you to feel disgusted. New research published in Philosophical Transactions of the Royal Society by the Environmental Health Group of the London School of Hygiene & Tropical Medicine showed that the emotion disgust may help protect you from disease and infection.
The study looked at a group of over 2,500 people and surveyed them on things that could be found disgusting -- on the list were things such as spoiled milk, open wounds, and bugs. The study found that those items on the list that could produce harmful effects in the body such as disease-carrying insects, rotten food, wounds, and coughing were the things that people were most likely to avoid. So the next time you find something disgusting it's probably for a reason that will help keep your body healthy -- keep being disgusted and take proper precautions to avoid any gross things that may befall you.
