Why is sleep so important? Although we naturally think of sleep as a time of rest and recovery from the stresses of everyday life, research is revealing that sleep is a dynamic activity, during which many processes vital to health and well-being take place. New evidence shows that sleep is essential to helping maintain mood, memory and cognitive performance.
It also plays a pivotal role in the normal function of the endocrine and immune systems. There is a link between duration and a variety of serious health problems, including obesity, diabetes, hypertension and depression.
Some of the most pressing problems we face as a society may be linked to poor sleep. Drowsiness in sleep-deprived drive is likely the cause of crashes, injuries and deaths. In addition, sleep and disorders are also reason for lost productivity, medical expenses, sick leave and property & environmental damage.
