Importance of Sleep : Six reasons not to scrimp on sleep
A recent survey found that more people are sleeping less than six hours a night, and sleep difficulties visit 75% of us at least a few nights per week. A short-lived bout of insomnia is generally nothing to worry about. The bigger concern is chronic sleep loss, which can contribute to health problems such as weight gain, high blood pressure, and a decrease in the immune system's power, reports the Harvard Women's Health Watch.
While more research is needed to explore the links between chronic sleep loss and health, it's safe to say that sleep is too important to shortchange.
