If you don’t get quality sleep on a regular basis, you might have a higher risk for heart disease and stroke. In a new study presented at the European Society of Cardiology Congress 2022, researchers at the French National Institute of Health and Medical Research studied 7,200 adults, looking at five sleep habits and baseline sleep scores. They checked each participant for coronary heart disease and stroke every two years for a decade. Only 10 percent had an optimal sleep score. Using a scale of 1 to 5, they calculated that for every one-point rise in sleep scores, the number of people who developed heart disease or stroke decreased 22 percent. Those rare people who achieved optimal sleep each night had a 75 percent lower risk of heart disease or stroke. The researchers claim that if we all had optimal sleep, we might prevent over 70 percent of cases of coronary heart disease and stroke each year.
