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.
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 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 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 and helps promote sleep by coordinating circadian rhythms.
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.
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.
By the age of 80, cerebral blood flow is approximately 20% less than at age 30, which means that the heart has less capacity for physical exertion and may feel fatigued more easily. As a result, we feel a gradual decline in our energy and endurance levels.
Sleep Changes in Older Adults. Most healthy older adults aged 65 or older need 7-8 hours of sleep each night to feel rested and alert. But as you age, your sleep patterns may change. These changes can cause insomnia, or trouble sleeping.
As reviewed above, most sleep parameters decline with age until the age of 60 years, but remain generally unchanged after 60 years of age. Also, older adults are less likely to complain of sleep problems and tend to accept some noticeable sleep alterations as normal changes with aging.
Sleep need gets less with age until around 20 years old when it stabilises. How much and how fast this happens depends on the person. It is normal for children to have daytime naps until 3 to 5 years old.
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.
“There is no such thing as a “fixed or ideal time” to go to bed which will suit all individuals. It is generally advisable to fall asleep between 10 pm to midnight as for most people this is when the circadian rhythm is at a point that favours falling asleep.”
This position can also signal emotional and physical dependence on your partner. Holding hands while sleeping is common for couples with strong relationships. They hold their sweetheart's hand to show their partner that they will always be by their side. The relationship is so strong that their trust is unbreakable.
As we age, our circadian rhythms — the internal “clock” that coordinates the timing of our bodily functions, including sleep — change. That's why older adults tend to become sleepier in the early evening and wake earlier in the morning compared to younger adults.
Poor airway health causes mouth breathing. When the airway is narrowed or blocked, patients resort to breathing through their mouths because they're not getting enough oxygen from nasal breathing.
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.
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.
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.
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.
In adults, a nap typically includes all the stages of sleep but in different proportions than regular nightly sleep. Naps are a useful stopgap for people who struggle to get enough sleep at night. But health experts agree that napping does not provide the same restorative power as a full night's rest.
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.
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.
The most common reason you're waking up tired is sleep inertia. Sleep inertia is the groggy feeling you get when you first wake up. It can last anywhere from 15 minutes to about two hours, and it's totally normal, even if you've had enough sleep. Sleep inertia is no joke, though.
Most of the time fatigue can be traced to one or more lifestyle issues, such as poor sleep habits or lack of exercise. Fatigue can be caused by a medicine or linked to depression. Sometimes fatigue is a symptom of an illness that needs treatment.
