Ever wonder why some people catch the cold that’s going around while others don’t? Many factors contribute to your body’s ability to fend off a cold. Aric Prather, a psychologist at the University of California found that those who sleep less than six hours per night are four times more likely to catch a cold virus than those who sleep seven or more.
Research also suggests that factors such as chronic stress, smoking, and lack of exercise can also increase susceptibility to cold germs.
