According to Xinhua News Agency’s latest report, experts in the United States have shown that if a person sleeps less than 7 hours a day, it will reduce his immunity, which will greatly increase the chance of catching a cold.
Why is it less likely to catch a cold when you sleep?
Researchers at Carnegie Mellon University used 153 volunteers to get them in contact with the cold virus and then “closed” for 5 days. During this time, the sleep time of these volunteers was different. After the expiration, the researchers measured their sleep, cold symptoms and the amount of antibodies in the blood. Finally, it was found that people who slept less than 7 hours a day had a 2.94 times more chance of sneezing, sore throat and other cold symptoms than those who did not.
Researchers say that low sleep quality may affect cytokines or histamine, which affects the body’s immune function. Therefore, the frequent occurrence of cold symptoms in winter may be related not only to changes in the weather, but also to the individual’s daily sleep time. The shorter the sleep time, the greater the impact of immunity, and the higher the chance of catching a cold.
