Chronic sleep deprivation is associated with an increased risk of hypertension and stroke

While short naps have been proven to have many positive health effects, a recent study warns against frequent sleep breaks. A correlation between regular sleep and a higher risk of hypertension and stroke was actually established by this work, which was published on Monday in the scientific journal Hypertension.

This link was identified by researchers at Central South University in China from data available in the Biobank database. The latter compiled between 2006 and 2010 the medical information of 500,000 British adults aged 40 to 69. Surveys were also conducted with these participants about naps, specifically slate.

12% increased risk of hypertension

The study first made it possible to identify the typical amateur profile of regular naps. These are usually men who “smoke, drink daily, have a low level of education and income and report insomnia and snoring”, the scientists found. They have an overall risk of hypertension increased by 12% and a risk of stroke increased by 24%.

However, these additional risks are not directly related to sleep, but to its cause: lack of sleep. “Poor nighttime sleep is associated with poor health, and not getting enough sleep to compensate for that,” explains clinical psychologist and sleep expert Michael Grandner.

A direct or indirect link

Tracking the increased risk of stroke due to direct sleep is excluded. A 2008 study, for example, showed that sleep increases blood pressure, and with it the risk of stroke.
