Why with age, worsens the quality of sleep?

At different ages required different number of hours of sleep

For anybody not a secret that in middle and old age sleep about 6-7 hours a day instead . However, researchers are more concerned about not reducing the number of hours of sleep with age, and sleep quality. The fact is that with aging many people experience unhealthy sleep due to age-related physiological changes. So, according to the meta-analysis conducted by experts from the University of California Berkeley, these changes can begin at the age of thirty years. A study published in the journal Neuron. The results showed that the older we get, the more disturbed our ability to sleep at night, during which the body recovers and gains strength, that accelerates the aging process.

Sleepless nights

According to researchers from Oxford University, people around the world due to sleep deprivation — the condition that occurs due to chronic . In addition to the increased risk of developing cardiovascular disease, obesity, diabetes, cancer, and depression, lack of sleep lowers immunity and impairs cognitive function. However, with age, our need for the number of hours of sleep is markedly reduced, and older people in General sleep an hour less than young, which is natural and not harmful to health process. However, with age, sleep loses its restorative function. restorative sleep tends to decline with age. People spend less time in deep sleep phase (Delta sleep), which is responsible for the normal operation of the memory and helps to restore psychological and physiological health.

Researchers believe that changes in sleep quality with aging occur unbeknownst to the person.

Age-related changes are felt starting thirty years predominantly in men. EEG, or electroencephalography, in some men, reduced by 50% compared to the dream at the age of 20 years. For women the decline is smaller but still up to 25%. This contributes to lethargy during the day and reduces the quality of sleep. Due to the fact that lack of sleep produces daytime sleepiness according to the survey 2007,10% of people aged 55 to 64 years sleep during the day and 25% of people aged 75 to 84.

Drowsiness sneaks up on you

According to scientists, the body can get used to loss of sleep and mask the symptoms. In addition, studies show that the need for sleep in the elderly is accumulated and is chronic, the brain, however, for some reason, less sensitive to it. Experts believe that these occur so slowly that people don't realize. But is it possible to reverse such changes, because they are directly connected with the aging process?

Given that a similar condition may be due to biologically, probably, science can do very little. The researchers called a healthy lifestyle, balanced diet, regular exercise and the ability to cope with stress, the best solution to the problems with sleep quality. As for sleeping pills, most drugs have limited scope and mainly aimed at coping with anxiety.
