A third of American adults say they sleep less than the recommended seven to nine hours. The optimal amount of sleep is highly dependent on the individual, but most people would likely be happier and healthier if they had between 60 and 90 minutes more sleep per night, according to the American Psychological Association.

But even people who get the recommended amount of uninterrupted sleep may be troubled by daytime fatigue and excessive sleepiness because of a variety of conditions that cause sleep problems.

Each of these four stages has its own role in promoting good health. Here are 19 secrets to sleep better at night.
