Stop Avoiding That Ick Feeling of Disgust—It Could Actually Be Keeping You Healthy
In a new study published in the journal Philosophical Transactions of the Royal Society, more than 2,500 people (with an average age of 28, and 66 percent female) completed an online survey including 75 scenarios. The participants were asked them to rate their level of disgust for each situation, and the results showed that people's disgust is spurred by six triggers: poor hygiene, disease-carrying animals and insects (particularly mice and mosquitoes), spoiled food, risky sexual behavior, infection cues (like people coughing), and lesions (like blisters, boils, or pus). According to experts, feeling disgust in reaction to these triggers is basically a protective biological response that has kept people away from harmful pathogens for centuries.

The disgust response today may or may not be a good guide to what might make us sick today," lead study author Val Curtis, PhD, director of the Environmental Health Group, told CNN. "We expected that disgust would mirror types of disease, but it seemed to rather reflect the types of things and people that should be avoided so as not to risk catching something infectious."
