According to the authors of Power Sleep: The Revolutionary Program that Prepares Your Mind for Peak Performance, most adults need at least eight hours of uninterrupted sleep nightly in order to perform at their peak. The key word there is uninterrupted. Our bodies depend on the deep sleep cycles to renew chemicals that keep all of our systems working in top order. Many of the interruptions of our sleep during the night never quite rouse us to full waking, but they do prevent our bodies from settling into that all-important deep sleep. Because we never fully wake, we get up in the morning believing we've had a full eight hours of sleep, and can't figure out why we're still so tired.

The five most common causes of interrupted sleep are:

- poor sleep environment
- mental stress
- physical stress
- improper diet and lack of exercise
- tossing and turning

While you're on your own with the diet and exercise, the right mattress can go a long way to relieving sleep interruptions caused by physical stress like body aches and pains, and the effects of tossing and turning. Choosing a mattress with the right combination of support, comfort and motion isolation can virtually eliminate the aches and pains that come from sleeping without the support your spine needs, and from the interruptions caused when your sleep partner tosses and turns. The resulting good night's sleep will put you in a better place to deal with the daily mental stresses, which will also help you to get a better night's sleep.
