A recent study has re-confirmed the relationship between length of sleep and the common cold infection. One hundred and sixty four people (164) people were given trackers to monitor their sleep for a week and then given live cold virus shots in their nose and quarantined in hotelfor five days where there monitored for cold infection.
Those who had six or less hours of sleep a day were at risk of cold four times more than those who had seven or more hours sleep; in more specific terms, 39 percent of those who had six or less hours of sleep had cold while only 18 percent of those who had seven or more hours of sleep had cold. Other factors had been accounted for; such as age, weight, stress and pre study antibody level.
The study was published in the 2015 September issue of Journal Sleep.
