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 among older people is a normal part of aging – but it may also foreshadow Alzheimer's disease and other dementias. And once dementia or its usual precursor, mild cognitive impairment, are diagnosed, the frequency and/or duration of napping accelerates rapidly, according to a new study.
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.
A midday snooze can be helpful, but the need for one might signal chronic sleep deprivation. In many cultures, napping in the afternoon is not only common, but a regular part of daily life.
Napping, as well as sleeping too much or too little or having poor sleep patterns, appears to increase the risk for cardiovascular disease in older adults, new research shows.
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.
Every child is different, but most kids start reducing naptime around 18 months and dropping their afternoon nap sometime between the ages of 3 and 4.
Naps for adults should be no more than an hour and probably best kept to the 15- to 20-minute range. Anything beyond that – especially considering the time of day – could have consequences. We caught up with sleep medicine specialist Nancy Foldvary-Schaefer, DO, MS, for more insight on how long your nap should be.
However, Matthew Walker, a professor of neuroscience at the University of California, Berkeley, and author of Why We Sleep, said people who have trouble falling asleep at night should approach naps with caution, and that everyone should avoid napping after 3pm.
The Centers for Disease Control and Prevention defines an “older adult” as someone who is at least 60 years old. Many states may also have different definitions of “elderly” when determining what resources are available in cases of elder abuse, although most states commonly use 65 years of age as the cut-off.
It can be a normal response to physical activity, emotional stress, boredom, or lack of sleep, but it can also signal a more serious mental or physical condition. Everyone feels tired now and then.
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.
The researchers found that as people aged, they napped more often and for longer periods. They determined that these longer, more frequent naps increased the risk of being diagnosed with AD.
Is a Two-Hour Nap Too Long? A 2-hour nap may make you feel groggy after you wake up and you might have trouble falling asleep at night. Aim for napping up to 90 minutes, 120-minutes if necessary. Napping every day for 2 hours could be a sign of sleep deprivation and should be discussed with a doctor.
Longer and more frequent daytime naps were associated with higher risk of Alzheimer's dementia. Interestingly, more excessive (longer or more frequent) daytime napping was correlated with worse cognition a year later, and conversely, worse cognition was correlated with more excessive naps a year later.
In part, it is physiological: Our normal circadian cycle dictates a period of sleepiness or decreased alertness in the afternoon. However, sleep disorders, medical disorders, stress, insaufficient sleep or poor eating habits can also cause excessive sleepiness at this time.
“Napping for just 20 minutes may provide ample benefits, including improved alertness, mood, and vigilance,” says Aarthi Ram, MD, a sleep neurologist at Houston Methodist Willowbrook Hospital. It may even help you learn more efficiently.
In general, the best nap length for adults is about 20 minutes and no longer than 30 minutes. Sleeping for 20 minutes allows the napper to get a bit of light sleep to boost alertness without entering into deep sleep. Waking up from deep sleep can cause grogginess and actually worsen sleepiness.
Excessive daytime sleepiness in older adults may be a symptom of health issues like sleep apnea, cognitive impairment, or cardiovascular issues. Sleep apnea: Obstructive sleep apnea can cause pauses in breathing during sleep.
However, with age, it can become a struggle to bathe or shower daily. This may be due to mobility or simply not having enough energy. But for the elderly, having a shower once or twice a week is sufficient to keep skin conditions and infections at bay.
Hypersomnia means excessive sleepiness. There are many different causes, the most common in our society being inadequate sleep. This may be due to shiftwork, family demands (such as a new baby), study or social life. Other causes include sleep disorders, medication, and medical and psychiatric illnesses.
As people age, they tend to sleep more lightly and often awaken during the night from achy joints or the need to go to the bathroom. Many people compensate for this lost sleep by catching a restorative nap during the day. That's normal.
Your body naturally experiences a circadian rhythm, which is responsible for you feeling alert and tired throughout a 24-hour period. Just as this rhythm makes you tired at night, it also makes you sleepy with decreased alertness in the afternoon, especially between 1PM and 4PM.
Most sleep experts recommend napping no later than 2 pm. As discussed above, napping prior to the mid-afternoon results in a combination of light and REM sleep, whereas napping after 2 pm results in more slow-wave sleep.
