Did you know too much, or too little sleep can affect your cardiac health? According to a study of over 116,000 people in seven regions of the world, people who slept longer than the recommended duration (8-9 hours) had an increased risk of dying or developing diseases of the heart or brain.
The study found that:
- Those who slept a total of 8-9 hours a day had a 5% increased risk.
- Those who slept between 9-10 hours had an increased risk of 17%.
- Those who slept for more than 10 hours a day had a 41% increased risk.
The Science Behind It
The lead author of the publication, Chuangshi Wang, PHD said “Our study shows that the optimal duration of estimated sleep is six to eight hours per day for adults. Given that this is an observational study that can only show an association rather than proving a causal relationship, we cannot say that too much sleep per se causes cardiovascular diseases. However, too little sleep could be an underlying contributor to death and cases of cardiovascular disease, and too much sleep may indicate underlying conditions that increase risk.
