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. If a child takes naps often past this age, he or she might not be sleeping enough at night.
The average amount of sleep needed by adults and kids
Before we dive into tips, it's good to start with a baseline. According to the National Sleep Foundation, adults between 25 and 64 years of age need an average of 7 to 9 hours of sleep per night. Adults 65 and older need 7 to 8 hours per night.
As you age your body produces lower levels of growth hormone, so you'll likely experience a decrease in slow wave or deep sleep (an especially refreshing part of the sleep cycle). When this happens you produce less melatonin, meaning you'll often experience more fragmented sleep and wake up more often during the night.
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.
Results show that the faces of sleep-deprived individuals were perceived as having more hanging eyelids, redder eyes, more swollen eyes and darker circles under the eyes. Sleep deprivation also was associated with paler skin, more wrinkles or fine lines, and more droopy corners of the mouth.
Sleeping on your back
According to Dr. Vasyukevic, the supine position is the best position all around for prolonging youthful skin. Not only does it prevent wrinkles due to the lack of wrinkle-inducing friction, it also stops the skin from feeling the pressure of your face "folding" into the pillow.
Sleep deprivation in both men and women was related to looking significantly more fatigued, having more hanging eyelids, redder eyes, more swollen eyes, darker circles under the eyes, more wrinkles/lines around the eyes, more droopy corners of the mouth, and being perceived as more sad.
Going a night with little to no sleep can also decrease production of growth hormone, which helps to maintain the process of skin's tissue repair, as well. Skin repairs itself as we sleep to maintain its youthful appearance. If you don't sleep well at night, you may find yourself looking “older” in the morning.
Interestingly, older adults need about the same amount of sleep as younger adults — seven or more hours of sleep per night.
A study suggests that just one night of sleep deprivation may be linked to structural changes in the brain, similar to those seen in aging. Going just one night without sleep may make the brain look older, as if it had suddenly aged one to two years overnight, a new study suggests.
Practice relaxation techniques at bedtime. Do not watch television or use your computer, cell phone, or tablet in the bedroom. Try to go to bed at the same time every night and wake at the same time each morning. Use the bed only for sleep or sexual activity.
Which age group struggles the most with sleeping? It's young adults, survey says. More than 1 in 4 adults ages 18 to 24 experience insomnia every night; it's the highest rate of insomnia out of any age group in the U.S., according to a recent survey from Norwegian health and wellness publication Helsestart.
Some recent studies suggest that poor sleep contributes to abnormal levels of beta-amyloid protein in the brain, which in turn leads to the amyloid plaques found in the Alzheimer's brain.
People with dementia often have issues with sleep with their memory seemingly worse after a bad night. However, the evidence is unclear on whether poor sleep is a risk factor for dementia.
Even without these conditions, simply sleeping less than 5 hours a night on average reduces your life expectancy by 15%. For someone with a standard life expectancy of 78 years, that is almost 12 years off your life.
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.
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.
Some people with insomnia experience changes in their sleep cycles and, as a result, may have more stage 1 sleep and less deep sleep. Stress and aging can also reduce levels of deep sleep. Additionally, people with conditions such as schizophrenia and Alzheimer's disease experience less slow wave sleep.
According to the results of a British survey of 2,000 people, women reach their peak of beauty at 31.
Exposure to light is a top cause of premature aging: Sun exposure causes many skin problems. Ultraviolet (UV) light and exposure to sunlight age your skin more quickly than it would age naturally. The result is called photoaging, and it's responsible for 90% of visible changes to your skin.
