Why does sleep quality worsen with age?

It's no secret that the average and the elderlyAged people sleep about 6-7 hours a day instead of 8-9 hours. However, researchers are more concerned not with a decrease in the number of hours of sleep with age, but with the quality of sleep. The fact is that as people age, many people experience unhealthy sleep due to age-related physiological changes. So, according to a meta-analysis conducted by specialists from the University of California at Berkeley, these changes can begin at the age of thirty. A study entitled “Sleeping and Aging” was published in the journal Neuron. The results showed that the older we get, the more our ability to sleep healthy is disrupted, during which the body is restored and gaining strength, which accelerates the aging process.

At different ages, a person needs a different number of hours of sleep

Sleepless nights

According to researchers from OxfordUniversity, people all over the world suffer from sleep deprivation - a condition that occurs due to chronic lack of sleep. In addition to the increased risk of developing cardiovascular disease, obesity, diabetes, cancer and depression, lack of sleep reduces immunity and impairs cognitive function. However, with age, our need for the number of hours of sleep decreases markedly, and older people generally sleep an hour less than young people, which is considered a natural and non-harmful process. However, with age, sleep loses its recovery function. restorative sleep tends to decline with age. People spend less time in the deep phase of sleep (delta sleep), which is responsible for the normal functioning of memory and helps to restore psychological and physiological health.

Researchers believe that changes in sleep quality with aging occur imperceptibly for humans.

Age-related changes make themselves felt sincethirty years mainly in men. According to EEG or electroencephalography, in some men, delta sleep is reduced by 50% compared with sleep at the age of 20 years. For women, the decrease is less, but still reaches 25%. This contributes to lethargy during the day and reduces the quality of sleep. Due to the fact that a lack of nighttime sleep causes daytime sleepiness according to a 2007 study, 10% of people aged 55 to 64 years sleep during the day and 25% of people aged 75 to 84.

Drowsiness is taken by surprise

According to scientists, the body can get used tosleep loss and mask symptoms. In addition, studies show that the need for sleep in older people accumulates and is chronic, but the brain, for some reason, is less sensitive to it. Experts believe that these changes are happening so slowly that people are not aware of them. But is it possible to reverse such changes, because they are directly related to the aging of the body?

Given that a similar condition may bebiologically determined, probably science can do very little.
