The results of a new study published in the Scientific Journal (Journal of the American College of Cardiology) revealed that sleeping for less than six hours every night would raise the risk of heart attack or injury.

The study authors found that for less than six hours per night, the risk of heart disease increased by approximately 35%, compared to those who slept 7-8 hours.

Lack of sleep contributes to raising the risk of atherosclerosis and narrowing of the arteries, and this happens quickly, meaning that the effect of sleep is fast on the blood vessels.

To find these results, the researchers targeted nearly 4,000 participants, with an average age of 46 without a history of heart disease, and then the participants were divided into four groups as follows:

  1. The first group got less than six hours of sleep per night
  2. The second group slept 6-7 hours per night
  3. The third group had 7-8 hours of sleep
  4. The fourth group in which the participants slept 8 hours or more.

After analyzing the results, the researchers found that those who slept less than six hours had a 27 percent increased risk.

For those who had poor quality sleep, their risk of heart disease increased by 34%.

He also found an association between those who slept more than eight hours a night and a higher risk of atherosclerosis as well, while women were more likely than men to do so.
