John Snow may or may not be COMING back in the next Game Of Thrones but he knows  Winter is definitely Coming and that means a new round of  colds and the sniffles. 

SHORT SLEEPERS:  Are Four Times More Likely to Catch a Cold

A recent study has shown that sleep can prevent colds. 

The study involved 164 healthy men and women, average age 30.  Aric Prather, assistant professor of psychology at the University of California, San Francisco, and his colleagues gave participants devices similar to a Fitbit® and monitored their sleep for a week. Then the study volunteers had a live cold virus sprayed into their noses and were quarantined for  five days. 

Here’s what researchers found:

 Those who averaged five to six hours of sleep a night were four times more likely to catch a cold than those who slept an average of seven hours. Four times.  Or, looking at it another way, about 39% of those who slept six hours or less got sick. Of those who slept more than six hours a night, only 18% got colds.

MIGHT BE TIME TO SERIOUSLY MAKE SURE YOU GET MORE SLEEP!

It’s striking,” Prather told National Public Radio. “We don’t know conclusively what happens, but there are a variety of pathways and they all work together and ultimately put people at risk.   -  Aric Prather, US San francisco.

Other factors such as stress and lack of exercise also come into play, but sleep plays a large role in helping our immune system do battle with invading viruses. 

So stay well this winter by sleeping more, exercising more and doing more yoga to reduce stress!  Oh and remember an apple a day keeps the doctor away.   :)
