Aging & Sleep
Sleep needs change over a person’s lifetime. Children and adolescents need more sleep than adults. Interestingly, older adults need about the same amount of sleep as younger adults — seven to nine hours of sleep per night.
Unfortunately, many older adults often get less sleep than they need. One reason is that they often have more trouble falling asleep. A study of adults over 65 found that 13 percent of men and 36 percent of women take more than 30 minutes to fall asleep.
Also, older people often sleep less deeply and wake up more often throughout the night, which may be why they may nap more often during the daytime. Nighttime sleep schedules may change with age too. Many older adults tend to get sleepier earlier in the evening and awaken earlier in the morning.
There are many possible explanations for these changes. Older adults may produce and secrete less melatonin, the hormone that promotes sleep. They may also be more sensitive to — and may awaken because of — changes in their environment, such as noise.
Older adults may also have other medical and psychiatric problems that can affect their nighttime sleep. Researchers have noted that people without major medical or psychiatric illnesses report better sleep.
Not sleeping well can lead to a number of problems. Older adults who have poor nighttime sleep are more likely to have a depressed mood, attention and memory problems, excessive daytime sleepiness, more nighttime falls, and use more over-the-counter or prescription sleep aids. Poor sleep is also associated with a poorer quality of life.
Poor sleep is not a normal part of aging. Many healthy older adults report few or no sleep problems. Sleep patterns change as we age, but disturbed sleep and waking up tired every day are not part of normal aging. If you are having trouble sleeping, see your doctor or a sleep specialist.
