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. There are many reasons why older people may not get enough sleep at night.
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.
What Does Sleep Look Like in Older Adults? 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.
Changes in sleep patterns, circadian rhythms, and lifestyles in older life make older adults more prone to taking naps during the daytime [4]. Older adults also take naps to counter excessive sleepiness and fatigue from comorbidities or medications [5].
Insomnia in the Elderly
In elderly individuals, sleep‐maintenance insomnia and early awakening are more common complaints than sleep‐onset insomnia; this is likely due to the age‐related changes in sleep architecture and circadian rhythm described above.
Sleep Deprivation Symptoms
Muscle strength and endurance diminish, vital organs cannot function at optimal levels, pain tolerance decreases, and insulin production and effectiveness decrease. The immune system is also weakened, which leads to a greater risk of infections and illnesses.
Older people wake up more often because they spend less time deep sleep. Other causes include needing to get up and urinate (nocturia), anxiety, and discomfort or pain from long-term (chronic) illnesses. Sleep difficulty is an annoying problem.
Their organs are slowing down, and they have less energy. As a result, their body needs more rest to work effectively. When people grow older, they also spend more time sleeping because they can't do as many things as quickly as before.
What to expect: As we continue to age, we may be concerned about losing cognitive function. It may be harder to learn new tasks, recall information or keep track of everyday household items. That's normal as our brain grows older. The brain changes caused by Alzheimer's disease, however, are not a normal part of aging.
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. There are many reasons why older people may not get enough sleep at night.
Who is Defined as Elderly? Typically, the elderly has been defined as the chronological age of 65 or older. People from 65 to 74 years old are usually considered early elderly, while those over 75 years old are referred to as late elderly.
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.
The Best Time to Sleep Is Between 8 p.m. and Midnight
To align our sleep schedules with our body's natural cycles (our circadian rhythms), adults should go to bed when it's dark out, after 8 p.m. We also get deeper, more restorative sleep when our sleep time begins before midnight.
There are plenty of potential culprits. Medications for blood pressure, sleep problems, pain and gastrointestinal reflux can induce fatigue, as can infections, conditions such as arthritis, an underactive thyroid, poor nutrition and alcohol use. All can be addressed, doctors say.
2-Hour Naps and 3-Hour Naps
A 2 hour nap and 3 hour nap seem great but chances are, napping for this prolonged period may have more ill effects than better. You may feel more groggy after a 2 hour nap, and may suffer insomnia that night after a 3 hour nap. The best nap length when sleep-deprived is up to 90 minutes.
Napping too much.
Long naps in the afternoon or later make it harder to stay asleep at night. Consuming too much caffeine.Caffeine (in coffee, tea, and sodas) blocks a brain chemical called adenosine that helps you sleep. Go light on caffeine-containing foods and drinks beyond the early afternoon.
Your Bones, Joints, and Muscles
Your muscles get weaker, and the tendons -- which connect muscles to your skeleton -- get stiffer. 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.
It's never too late to start over because change is a natural part of life. Whether you feel stuck in a career path, relationship, or unhealthy habit, you can reboot your life and get out of the rut with the right resources and strategies.
According to the National Institutes of Health (NIH), healthy seniors should walk 7,000 – 10,000 steps per day. That's an average of three to three and a half miles throughout the course of a day.
Cardiovascular decline: One geriatric medicine study showed that long sleep duration is associated with an increased cardiovascular mortality rate in seniors 65 and over. It showed that more than 14 hours of sleep during a 24-hour cycle on a constant basis increases cardiovascular morbidity by 43%.
Beneath the surface, your body is aging too, and sleep loss can speed up the process. A study done by UCLA researchers discovered that just a single night of insufficient sleep can make an older adults' cells age quicker. This might not seem like a big deal, but it has the potential to bring on a lot of other diseases.
Sleeping all day can cause confusion and various cognitive and physical problems for the elderly. It also puts them at higher risk for accidents and injuries. Below are some of the reasons your senior parent may sleep a lot during the day and steps you can take to prevent each issue.
According to the CDC14, the most common sleep disorders are insomnia, narcolepsy, restless leg syndrome, and sleep apnea. All of these disorders can cause waking up in the middle of the night, but it is one of the characteristics of insomnia, in particular.
Cognitive behavioral therapy for insomnia (CBT-I) is the preferred first-line treatment for chronic insomnia in adults and has been endorsed as first-line therapy by multiple societies and guideline panels [1-5]. Overall, the evidence base is stronger for CBT-I than for medications.
Avoid prolonged use of electronic devices with a screen, such as laptops, smartphones and ebooks before bed. Relax your body. Gentle yoga or progressive muscle relaxation can ease tension and help tight muscles to relax. Make your bedroom conducive to sleep.
