The Science Of Sleep
A restful night of sleep is absolutely essential to maintaining a healthy lifestyle. People who sleep at least 8 hours during the night tend to wake up happier. Sleep quality degrades as we age, so it can become even more important to create the best sleep environment that you can for yourself.
Experts agree that the temperature of your sleeping area and how comfortable you feel in it affect how well and how long you sleep. Most significantly affected is the quality of your REM sleep, the stage in which you achieve the deepest level of rest and rejuvenation. Overall it is clear that when you are too hot or too cold, your total sleep time is reduced while your wakefulness is increased. These sleep disturbances can have long term detriments to your well-being.
