As you may painfully know: Sleep gets more difficult the older you get. Older adults are less able, on average, to obtain as much sleep, or as restorative a sleep, as young adults. The problem gets so bad that by our 80s, the lack of sleep can have major health ramifications, though we don’t always notice.

Older adults face a number of challenges. The first is a reduction in the quantity and quality of deep sleep—the stage that beneficially overhauls your cardiovascular, immune and metabolic systems and refreshes learning and memory abilities. As you enter your 30s and 40s, your deep-sleep brain waves become smaller, less powerful and fewer in number. Reductions in deep-sleep quality increase your risk of heart attacks, obesity and stroke, as well as the buildup of a toxic brain protein—called beta amyloid—that is linked?to Alzheimer’s disease.

Passing into your mid- to late-40s, age will have stripped you of 60% to 70% of the deep sleep you were enjoying as a teen. By the time you reach age 70, you will have lost 80% to 90% of your youthful, restorative deep sleep.

Because of sleep fragmentation, older people will suffer a reduction in sleep efficiency, defined as the percent of time you were asleep while in bed.
