Elderly people need to sleep no more and no less than the number of hours determined by doctors. If they do not sleep enough, then the heart suffers, if they abuse sleep, then the risk of getting dementia is high, cardiologist Vladimir Khoroshev told Sputnik radio.
Eight hours is the optimal number of hours of sleep for the average person. It is believed that during this time the body is fully restored. And if in youth the lack of sleep is quite easily compensated for, then older people definitely need to sleep as much as they should, this is vital, explains Vladimir Khoroshev.
"People in the age, those who are over 55 years old and approaching 60 years old, should have a certain sleep pattern. They should always have restful sleep at least eight hours a day. If the elderly sleep less, then their body will not physically to have time to restore the resource base, which will affect the work of all organs. The brain, heart, liver and stomach will suffer from this. This must be remembered, "the cardiologist advised on the air of Sputnik radio.
At the same time, too much sleep for older people is no less dangerous than not getting enough sleep. Cardiologist Vladimir Khoroshev warns that sleep abuse leads to dementia.
"Do not forget that many people of the age abuse sleep. They say that they are tired of their lives and want to sleep more. The fact is that too long sleep in older people is also harmful. Studies have shown that sleep is more than 9, 10 or even 11 o'clock increases the risk of atherosclerotic brain damage or encephalopathy. This disease leads to cognitive impairment of the brain. As a result, this can lead to senile dementia. Excessive sleep is also undesirable, "Dr. Horoshev said in an interview with Sputnik radio.
