Lack of sleep encourages colds

March 11, 2009


We all know that a good night’s sleep can make many things better, but it can also protect you from catching a cold. The less sleep you get, then the more at risk you are of developing a cold if you have been exposed to the virus according to a study conducted by researchers from Carnegie Mellon University. Sleep is vital to help the body repair and renew itself and a poor sleep pattern can lead to a compromised immune system. However it wasn’t before realised that something as ordinary as our reaction to a cold is dependent on us getting a good night’s sleep.

So how much is enough? In the study, people who slept an average of less than seven hours a night were nearly three times more likely to develop cold symptoms than people who slept eight or more hours a night. Restless sleeper? Well unfortunately you are nearly six times as likely to develop cold symptoms than those who put their head down and sleep right through.
