Recent studies have claimed that chronic sleep deprivation appears to be an important causal factor in developing hypertension. And cardiovascular disease is indeed associated with sleep disorders. Sleeping for short periods of time raises the average blood pressure and heart rate, which may increase the stress on the cardiovascular system. In the most stressed young and middle-aged population, those who sleep less than six hours a night on average are more than twice as likely to develop hypertension as those who get enough sleep, and even when factors such as obesity and diabetes are taken into account, there is still an important link between sleep deprivation and hypertension.
