If you, like many others, are dreading the fall season and the colder weather because of impending illnesses like the common cold, maybe you should hit the hay a little earlier tonight.
A recent study published in the journal Sleep recorded the sleep patterns of 164 men and women purposely infected with a common cold virus.
The results?
The people who were sleeping 5-6 hours a night were four times more likely to actually catch a cold versus the people who were sleeping at least seven hours per night.
“There’s evidence that people who don’t get enough sleep show higher levels of inflammation,” says Sheldon Cohen, a psychologist at Carnegie Mellon University who co-authored the study.
That may not be the only reason sleep helps protect people from getting sick. Other studies suggest age plays a role, and smoking, chronic stress and a lack of exercise can also break down our immune systems and make us more susceptible.
