The amount of sleep you get can affect your lifespan and not just because a sleepy driver is at risk of a car accident!  In epidemiological studies, sleeping too little (fewer than six hours) or substantially more (over nine hours) has been shown to put people at greater risk of death. Quality of life is also on the line: A good night’s sleep can help you ward off stress, depression, and heart disease.

You can learn to fall asleep more quickly by keeping your bedroom dark and distraction-free and having the temperature on the cool side. Meditation exercises can set the stage for a good night’s sleep and an inexpensive noise machine may help with relaxing sounds.
