The fact that you’re waking in the middle of the night is not necessarily a sign that anything is wrong. Indeed, there is plenty of evidence that “segmented” sleep can be as effective as a single block of sleep, so long as you’re getting a total of seven to eight hours.
Scientific evidence tells us that sleep is the time when the brain’s physiological maintenance systems kick in. Without adequate shut-eye, your cellular janitors won’t have time to clean up all the waste left over from a day’s worth of thinking. So be sure not to shortchange yourself, because a brain filled with cognitive trash will not serve you well.
