1 Sleep

Sleeping is a repeated and naturally occurring state of mind that inhibits sensory activity, voluntary muscles and reduced knowledge of surroundings.

There are two types of sleep, the REM (Rapid Eye Movement) and non REM sleep. In REM sleep, the person may view vivid dreams and most of the limbs, muscles are paralyzed and heart rate, breathing and temperature of body are unregulated.


In Non REM sleep, the person falls into deep sleep in stages starting from light sleep, total sleep and then finally deep sleep in which person goes into a total hibernation like stage with no response to external surroundings.

University of California and its team of researchers, along with researchers from University of San Francisco, Carnegie Mellon University and the University of Pittsburgh, worked together on an extensive study to use objective sleeping measures which could connect people’s natural sleeping habits to the risk of them getting sick.

164 volunteer men and women from ages of 18-55 were administered rhinovirus, which is a common cause of common cold. A week prior to the experiment, researchers had collected data measuring the participant’s normal sleep routines via a watch type sensor, measuring quality of sleep through the night.

The researchers then isolated the volunteers who were suffering from cold in a hotel for the next seven continuous days and continued administering the cold causing virus via nasal drops and continuously collected and analysed the mucus samples from them to see if the virus has started its effect.

3 Results of the study

After seven days, the researchers analysed the data and got astounding results.

The results found that volunteers who had slept for less than 6 hours a night during the week were 4.2 times more vulnerable to catch the cold as compared to the volunteers who had slept for more than 7 hours a night.

Participants who slept for less than 5 hours during the night were 4.5 times more likely to get sick form the virus.

The researchers noted that the study was another evidence that sleep, like diet and exercising is crucial for leading a healthy life and people’s attitude and concern towards sleep should change.

“Sleep often takes a back seat to other health behaviors in terms of attention and investment, this shouldn’t be the case.” said lead study author Aric Prather of UCSF’s Department of Psychiatry.
