According to a study published in the Journal of Stroke, 50%–70% of subjects with acute stroke or transient ischemic attack have sleep disorders, especially sleep apnea syndrome, and the proportion is significantly higher than that of ordinary people. Another large prospective study (Women’s Health Initiative Study) of 93,175 women aged 50–79 years showed that sleeping less than 6 hours a night was associated with a 22% increased risk of ischemic stroke.


The Journal of the American College of Cardiology published a study in 2018 that showed that, compared with people who slept 6–9 hours, people who slept less than 6 hours had a 20-fold increased risk of myocardial infarction. Even among people with a higher genetic risk of myocardial infarction, maintaining a healthy and adequate amount of sleep can reduce the risk of myocardial infarction by 18%.

Harvard researchers found that maintaining a consistent sleep pattern of seven to eight hours in early to mid-adulthood reduced a woman’s risk of developing type 2 diabetes.
