Sleep needThe term information need is often understood as an individual or group's desire to locate and obtain information to satisfy a conscious or unconscious need. Rarely mentioned in general literature about needs, it is a common term in information science.https://en.wikipedia.org › wiki › Information_needs
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 requirements stabilize in early adult life, around the age of 20. Individuals vary in their sleep needs but most adults require between 7 and 9 hours a night to feel properly refreshed and function at their best the next day. Many try to get away with less sleep.
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.
According to the research, the average American starts feeling old at the age of 47. Similarly, the average respondent starts to really worry about age-related bodily changes around 50 years old.
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.
Children and babies need a lot more sleep than adults. Newborns spend 16-20 hours a day sleeping. By age 2, children are finally spending more time awake than sleeping. Sleep is vital to children and babies because of the rapid brain development and growth that they're experiencing during this age.
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.
Preschoolers (3-5 years): 11-13 hours. School-aged children (6-13 years): 9-11 hours. Teenagers (14-17): 8-10 hours. Adults (18 and older): 7-9 hours.
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.
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.
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.
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.
Changes in production of hormones, such as melatonin and cortisol, may also play a role in disrupted sleep in older adults. As people age, the body secretes less melatonin, which is normally produced in response to darkness that helps promote sleep by coordinating circadian rhythms.
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).
The two most likely reasons you're always so tired no matter how much sleep you get are you've got high sleep debt or you're not living in sync with your circadian rhythm. You may also feel sleepy if you're ill, pregnant, or you've got a medical condition like anemia or diabetes.
What's the secret to happiness? Maybe seven hours of sleep. A recent survey of 2,000 people by mattress company Amerisleep suggests “perfectly happy” people get 7.1 hours of sleep per night. "Mostly happy" people sleep seven hours and "somewhat happy" people sleep 6.9 hours, the study shows.
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.
How Much Sleep Is Too Much? Sleep needs can vary from person to person, but in general, experts recommend that healthy adults get an average of 7 to 9 hours per night of shuteye. If you regularly need more than 8 or 9 hours of sleep per night to feel rested, it might be a sign of an underlying problem, Polotsky says.
ABSTRACT: Fatigue is a common symptom in elderly persons, but it is often ignored as many patients and healthcare providers assume it is a natural progression of aging or may mistake it for somnolence, dyspnea, or muscle weakness.
Fatigue in older adults sometimes occurs as a result of chronic pain from arthritis, fibromyalgia, or other chronic conditions. Your body may tire itself out from trying to manage the pain or inflammation, and living with chronic pain can also lead to mental or emotional fatigue.
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.
