Sufficient sleep is the basis of good health, but experts warn that even too much sleep is not beneficial for the body. Doctors warn that an excessively long night’s rest may be associated with an increased risk of serious diseases and in some cases even with a shortening of life, informs
This was pointed out by a chronobiologist and sleep expert Juan Antonio Madrid. According to him, the optimal length of sleep for most people ranges between 6.5 to 8.5 hours a day. “Sleeping less than six hours already starts to have negative effects, especially in the long term,” Madrid explained.
At the same time, he added that a little-known fact is that too much sleep can also be harmful to health. According to the expert, studies show that people who sleep regularly 10 to 12 hours a daythey have higher risk of metabolic diseases and even premature death. Excessive sleep is also associated with increased risk Alzheimer’s disease.
A friend also supports these findings Framingham Heart Studyaccording to which an increase in sleep time may indicate early stages of dementia. The researchers found that people who slept more than nine hours a day had a higher risk of developing the disease than those who slept less.
At the same time, Madrid points out that it is not yet completely clear whether long sleep in itself causes health problems or is rather a consequence poor quality and interrupted sleepwhich the body tries to compensate with longer rest. In any case, it can be a long sleep a signal that something is wrong in the body.
According to experts, too often people focus only on the number of hours of sleep, although its quality is equally important. The average person has several brief micro-awakenings during the night that they are not aware of, well they can affect the restorative effect of sleep.
It also plays a big role regularity. Epidemiological studies suggest that a consistent sleep pattern is related to longevity more than the number of hours spent in bed alone.
Madrid also emphasizes that naps during the day cannot replace a quality night’s sleep. The more significant the difference between night rest and daytime vigilance, the the better a person feels and the more his health benefits from it.
