"Staying overnight at a sleep center usually costs between  800 and  1,500. Most health insurance companies will cover most or all of the cost if you have a referral from a sleep doctor—check with your insurer to find out how your plan handles this."

"In some studies, wrist actigraphy accurately determined the person’s sleep/ wake cycle almost 90 percent of the time."

"Many people are so used to sleep deprivation that they don’t realize how tired they are; instead, they may see themselves as lazy, lethargic, or unmotivated."

"Cognitive therapy is often provided in combination with one or more behavioral therapies—what’s known as cognitive behavioral therapy (CBT). Research has shown that CBT is more effective than any behavioral technique used by itself, and that it’s more effective than sleeping pills."

"Doctors used to reassure older people that they needed less sleep than younger people to function well, but sleep experts now know that isn’t true. At any age, most adults need seven and a half to eight hours of sleep a day to function at their best. (..) Not surprisingly, the older we get, the more likely we are to supplement nighttime sleep with daytime naps."

"We know, for example, that the brain’s natural production of the hormone melatonin decreases significantly during adulthood and old age."
