Get More Sleep If You Don't Want to Catch Colds
Getting a good night's sleep just may help you avoid catching a cold. A study, published in the journal Sleep, is the first to show how objectively measured sleep can serve as a predictor of cold susceptibility.
Researchers from the University of California, San Francisco, used 164 people to test how sleep can affect a cold. Participants wore fitness trackers to monitor their sleep and were then given nasal drops with the common cold virus. After five days, almost one-third (29 percent) of the participants came down with cold symptoms.
People who got six hours of sleep or less per night the week before being exposed to the cold virus were four times more likely to contract the virus compared to people who got seven hours of sleep or more per night the week before. One researcher noted these findings remained constant regardless of age, stress levels, smoking, education or income. The one common factor was not enough sleep.
