Severe and fatal heart attacks are more common than Mondays. At the beginning of the week, the risk of suffering a lethal heart attack is 13% higher than expected.
Lack of sleep, busted schedules and stress are associated with heart attacks on Mondays. The circadian rhythm, which regulates the sleep and wake cycle, would play a decisive role in the timing of a heart attack, according to the researchers in Ireland and Italy. The study analyzed data from 10,528 patients hospitalized between 2013 and 2018 with the most severe type of heart attack.
