كم ساعة تنام؟ قلبك يُجيبك أولاً

A recent European medical study confirmed that the number of hours of sleep is not just a matter of rest, but a precise indicator of heart health, warning that both insufficient and excessive sleep increase the risk of heart disease by more than 30%. The study, published in the European Heart Journal, indicated that sleeping less than 6 hours or more than 9 hours a day is associated with irregular heartbeats and high blood pressure, as well as doubling the chances of coronary artery problems.

The researchers based their findings on the analysis of data from thousands of individuals, in addition to sleep deprivation experiments lasting 3 consecutive nights, during which participants were restricted to only 4 hours of sleep. The results showed rapid biological changes, including increased inflammation markers and decreased vascular flexibility, which demonstrates that the heart is affected even by short-term fluctuations in sleep.
