A new study published early last September in the American magazine “Sleep” has revealed that the risk of catching a cold is 4 times greater in people who do not get enough of sleep.
The study was conducted on a group of 164 people who agreed to be exposed to the cold virus. During that study, their sleep patterns were recorded, while taking into account a number of other factors. The sleep patterns of these individuals were measured during the week that preceded the study. Also, during the study, they were isolated in a hotel room in Pittsburgh, in the eastern United States, where they were given the cold virus via nose drops. Samples were then taken on a daily basis to observe the level of development of the virus.
When the study was completed, it was found that people who slept less than six hours a night during the week were 4.2 times more likely to catch a cold than those who slept more than seven hours per night. Therefore, the lead author of the study, Aric Prather of the University of California at San Francisco, found that the lack of sleep was the most important differentiating factor in this study. He added that the age of these people had no role here, as much as their stress, education or income levels, in addition to their status as smokers or non-smokers, etc. Thus, it was shown that sleep quantity was the most important factor to consider when trying to avoid catching a cold.
