Scientists have named the time of day when half of strokes occur

A stroke occurs, when the brain does not receive enough blood, depriving it of oxygen and nutrients. As a result, brain cells die. At the same time, studies show that the chance of experiencing a stroke is 80% higher at the same time of day.

So the work of the American Heart Association, published in the journal Stroke, showed that the probability of a stroke between 6 and 12 hours is 80% higher than at other times.

“The number of strokes registered between 6 a.m. and 12 noon is 49% higher, which increases the risk by 79% compared to other 18 hours a day,” scientists say.

They explain that this confirms the theory of circadian cycle fluctuations. The term refers to the difference in risk that varies depending on circadian rhythms.

The team's study was a meta-analysis of more than 30 previous papers that used data from 11,000 stroke patients.

The team found that the number of vascular events occurring between midnight and 6 a.m. is the lowest. When compared to the other 18 hours of the day, the reduction is 35%.
