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.
Daytime napping among older people is a normal part of aging – but it may also foreshadow Alzheimer's disease and other dementias.
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.
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.
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).
Older adults are more likely to take naps during the daytime due to age-related changes in circadian rhythms and sleep patterns. Cultural beliefs, chronic conditions, medications, and lifestyle changes can also contribute to daytime napping. Napping may impact health outcomes among older people.
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.
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.
Providing the person doesn't appear to be uncomfortable or distressed, then sleeping more during the day isn't normally a reason to be worried. However, if a person is lying down in bed and asleep for most of the time they will need to be looked after to make sure they don't develop any physical health problems.
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.
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.
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.
Most of Europe have similar views of old age to the World Health Organisation, believing old age starts at 65 years of age. In America, one researcher found that you are considered old at 70 to 71 years of age for men and 73 to 73 for women.
Hormones: As we age, our bodies secrete less of two important sleep hormones: melatonin and growth hormone. Melatonin is important because changes in the level of this hormone control our sleep cycle. With less melatonin, many older adults feel sleepy in the early evening and wake up in the early morning.
Aging has many wonderful aspects, but one of the many problems is that we do not have the stamina and energy we did when younger. That is a normal part of aging and just something that comes with the territory. However, being excessively tired or listless can be termed fatigue.
Late adulthood. The eighth and final stage of life is late adulthood. This stage refers to any individual who is older than sixty-five years old.
The major cause of death in the 55-64 age group is cancer followed by heart disease and injury. In the 75+ age group, the leading cause shifts to heart disease, and injury drops below Chronic Obstructive Pulmonary Disease (COPD), cerebrovascular diseases, and pneumonia.
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.
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.
In a new study, researchers have shown that excessive sleepiness during the day time among elderly who had normal mental acuity and cognitive powers is associated with the buildup of amyloid plaques in the brain that is typical of Alzheimer's disease.
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.
A long nap, such as two hours per day, could indicate sleep deprivation or another sleep disorder, which may need a doctor's consultation.
