Sleeping 7 hours a day is best for the heart

A new study shows that people who are snoring inside and who sleep more than or less than 7 hours a day have an increased risk of cardiovascular disease.

Cardiovascular disease is the number one killer in the United States.

Sleeping for more than 7 hours is also prone to cardiovascular disease.

The study also found that people who have been sleeping for 9 hours a day have a cardiovascular risk of 7 hours of sleep.

5 times.

  The study, published in the recently published journal Sleep, states that the most dangerous group is adults under the age of 60 who sleep 5 hours a day or annually; those who suffer from cardiovascular disease may be those who sleep for 7 hours a day.3 times.

If a woman sleeps only 5 hours a day or at least (including snoring), the risk of cardiovascular disease is two and a half higher than that of a normal sleeper.

  The researchers pointed out that short duration of sleep is associated with angina, and that sleeping too long or too short is associated with heart disease and stroke.

  Another study published in Sleep magazine pointed out that for those who must extend their sleep time, occasionally taking a good night’s sleep can also help with health.

  David Dingis, head of the Sleep and Time Biology team at the University of Pennsylvania School of Medicine, found that 142 adults who suffered severe deprivation for 5 days of sleep (that is, most people sacrificed sleep for work five days a week), the responseTime is slow and it is difficult to concentrate.

However, after a good night’s sleep, the increased alertness of the study improved significantly, with the greatest improvement being those who slept for 4 hours a day for 5 days a week and then slept 10 hours.

  Dingis suggested that if you have shortened sleep deprivation, you can use the morning to sleep for an hour or two, which helps to restore the body’s alertness.

  Because the length of sleep affects a person’s heart, the researchers cannot determine the cause.

However, they point out that the length of sleep affects endocrine and metabolic functions, and that deprivation of sleep leads to impaired glucose tolerance, decreased insulin sensitivity, and elevated blood pressure, all of which contribute to arteriosclerosis.
