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.
Daytime napping—which is reported to be more frequent in school-aged children and older adults—can occur in all age groups. Older adults are more likely to take naps during the daytime due to age-related changes in circadian rhythms and sleep patterns.
Sleep and Aging
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.
Daytime napping among older people is a normal part of aging – but it may also foreshadow Alzheimer's disease and other dementias.
Sixty percent of four-year-olds still nap. However, by five years of age, most children no longer need naps, with less than 30% of children that age still taking them. The number decreases even more by age six, where less than 10% of children nap. Nearly all children stop napping by seven years of age.
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.
CLEVELAND – A recent study has found that older adults who regularly nap for more than an hour a day had a 40% higher risk of developing Alzheimer's disease.
Around 20% of older people experience excessive daytime sleepiness, which may be a sign of an underlying health condition rather than merely old age. Excessive daytime sleepiness in older adults may be a symptom of health issues like sleep apnea, cognitive impairment, or cardiovascular issues.
As people age, they tend to sleep more lightly than when they were younger. Waking up during the night due to achy joints or the need to use the restroom becomes commonplace. Many seniors compensate for this lost sleep by catching a restorative nap during the day. That's normal.
Some sleep experts suggest that seniors actually need less sleep than other age groups. Most people need between 7 and 9 hours of sleep whereas many seniors can get away with 7.5 hours. Other experts believe that seniors need just as much sleep as the rest of the population.
Adults (18-64): 7-9 hours. Older adults (65+): 7-8 hours.
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).
Your Bones, Joints, and Muscles
This will decrease your strength and flexibility. In your 70s, you might lose an inch or two off your height as disks in your back flatten. Exercise, especially the weight-bearing kind, can help prevent these changes and may even reverse them.
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.
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'.
How much water do you need to stay hydrated? As a general rule, you should take one-third of your body weight and drink that number of ounces in fluids. For example, if you weigh 150 pounds, aim to drink 50 ounces of water each day.
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.
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.
The study found that men who had napped for an average of two hours or more per day at the beginning of the study were 66 percent more likely to develop clinically significant cognitive impairment than men who had only napped for 30 minutes or less a day.
In some instances, napping sets up a vicious cycle. You sleep during the day to make up for lost sleep at night, but then you have a harder time falling asleep at night because you slept during the day. "Limiting naps is one strategy to improve overall nighttime sleep," says Dr. Bertisch.
Fear naps are simply less common. Dr. Steven Feinsilver, the director of sleep medicine at Lenox Hill Hospital, tells me fear naps (or stress naps) are not something he hears about often, though there might be an easy explanation for that: “People come to me if they're not sleeping well,” he says.
A long nap, such as two hours per day, could indicate sleep deprivation or another sleep disorder, which may need a doctor's consultation.
