Contrary to popular opinion, older people don't need less sleep than the average person. In fact, adults require about the same amount of sleep from their 20s into old age, although the number of hours per night varies from person to person.
Sleep patterns tend to change as you age. Most people find that aging causes them to have a harder time falling asleep. They wake up more often during the night and earlier in the morning. Total sleep time stays the same or is slightly decreased (6.5 to 7 hours per night).
As people age, the body secretes less melatonin, which is normally produced in response to darkness that helps promote sleep by coordinating circadian rhythms.
Older adults need about the same amount of sleep as all adults—7 to 9 hours each night. But, older people tend to go to sleep earlier and get up earlier than they did when they were younger.
Most likely, you're still tired after eight hours of sleep because of these three factors: (1) you don't know your sleep need, (2) you're not taking into account your sleep efficiency, and (3) you carry sleep debt.
The cumulative long-term effects of sleep loss and sleep disorders have been associated with a wide range of deleterious health consequences including an increased risk of hypertension, diabetes, obesity, depression, heart attack, and stroke.
If you nap in the morning, the sleep consists primarily of light NREM (and possibly REM) sleep. In contrast, napping later in the evening, as your sleep drive increases, will comprise more deep sleep. This, in turn, may disrupt your ability to fall asleep at night. Therefore, napping late in the day is discouraged.
While a 30- to 90-minute nap in older adults appears to have brain benefits, anything longer than an hour and a half may create problems with cognition, the ability to think and form memories, according to the study published in the Journal of the American Geriatrics Society.
According to their internal body clock, most older adults need to go to sleep around 7 p.m. or 8 p.m. and wake up at 3 a.m. or 4 a.m. Many people fight their natural inclination to sleep and choose to go to bed several hours later instead.
Is 5 hours of sleep OK? 5 hours of sleep is not OK. Studies show getting five hours or less sleep puts you at greater risk of having two or more long-term health conditions.
There was a 65% higher death rate for people who regularly slept less than 5 hours on all nights, compared with people who regularly slept 6 to 7 hours per night.
Ageing, an inevitable process, is commonly measured by chronological age and, as a convention, a person aged 65 years or more is often referred to as 'elderly'.
Despite these trends, the research mostly agrees that six hours of sleep is not enough for most adults. Experts recommend that most adults need at least seven hours of sleep every night.
Age, Life Cycle and Evaluations of Personal Life
Fully 71% of those under age 50 expect their lives to be better in 10 years than they are today, as do 46% of those ages 50-64. By contrast, only about a fifth of adults ages 75 and older (19%) expect their lives to be better in the future than they are today.
Skin makes new collagen when you sleep, which prevents sagging. “That's part of the repair process,” says Patricia Wexler, MD, a dermatologist in New York. More collagen means skin is plumper and less likely to wrinkle. Only getting 5 hours a night can lead to twice as many fine lines as sleeping 7 would.
Usually, our energy declines because of normal changes. Both genes and environment lead to alterations in cells that cause aging muscles to lose mass and strength and to become less flexible. As a result, strenuous activities become more tiring.
In a new study recently published in the journal Alzheimer's & Dementia (2022), Li and colleagues report on the results of their long-term study of more than 1,400 older adults, which points to a link between excessive daytime napping and the risk of developing Alzheimer's disease (AD).
Boredom, depression, chronic pain and/or nutritional deficiencies can be some of the underlying causes that account for excessive daytime sleeping. Medications can also be a problem.
Could a sudden increased need for naps indicate a health problem? If you're experiencing an increased need for naps and there's no obvious cause of new fatigue in your life, talk to your doctor. You could be taking a medication or have a sleep disorder or other medical condition that's disrupting your nighttime sleep.
Instead, the best approach is to "do nothing. Don't sleep in, don't nap, and don't go to bed early," says Perlis. "Acute insomnia will fix itself in three to five days if you do nothing.
A long nap, such as two hours per day, could indicate sleep deprivation or another sleep disorder, which may need a doctor's consultation.
This is because our brain is constantly forming new connections while we are awake. The longer we are awake, the more active our minds become. Scientists believe that this is partly why sleep deprivation has been shown to reduce symptoms of depression. However, there are negative outcomes of this, too.
A number of chronic health conditions may be affected by not getting enough sleep on a regular basis. These include high blood pressure, diabetes, heart failure, coronary heart disease and some cancers. You may also be more likely to have a stroke. You're at greater risk of injury.
