People who get inadequate sleep are more vulnerable to infection than those who are well rested. In one study, researchers injected healthy volunteers with a cold virus. Those who slept less than 7 hours a night for the previous week were 3 times more likely to develop symptoms than those who got 8 hours or more. In another study, people who got only 4 hours sleep for several nights in a row had a weaker immune response to the flu vaccine than those who slept between 7.5 and 8.5 hours.
Don’t skimp on your sleep. It’s only going to de-rail you down the line. People seem to wear sleeping to little or working too hard as a badge of honor. It’s not. It’s a sign of being unbalanced. In actuality, it’s a sign of not handling your life properly. So the next time you hear someone bragging about how much they work and how little they sleep, let them know they are setting themselves up for failure. Buy them a box of tissues, because they’ll be needing it for the cold they are about to get.
