Nap for hypertension?
A nap around lunchtime not only leads to an improvement in mood and new energy, but it is also associated with a significant drop in blood pressure according to a recent study. Researchers compared the resulting drop in blood pressure with the effects of low-dose antihypertensive drugs.
The scientists at Asklepieion General Hospital have determined in their current study that a short nap during the day can offer the same benefits in lowering blood pressure as low-dose antihypertensive drugs. The doctors published the results of their studies at the 68th annual scientific session of the American College of Cardiology.
Nap as effective as medicine?
Afternoon sleep seems to lower blood pressure on the same scale as other lifestyle changes, experts say. For example, reducing the intake of salt and alcohol can lower blood pressure by three to five mmHg, says study author Manolis Kallistratos of the Asclepeion General Hospital in Voula, Greece. In comparison, low-dose antihypertensive drugs lower blood pressure by an average of five to seven mmHg.
How much helps nap to lower blood pressure?
Overall, a nap during the day was associated with an average blood pressure drop of 5 mmHg, which the researchers say is comparable to what is expected from other known antihypertensive measures. In addition, systolic blood pressure decreased on average by 3 mmHg per 60 minutes nap. "These results are important because a drop in blood pressure to 2 mmHg may reduce the risk of cardiovascular events such as a heart attack to ten percent," Kallistratos explains in a press release from the American College of Cardiology.
According to the findings of the study, someone who takes a nap during the day can take advantage of lowering his high blood pressure. This is the first study to prospectively assess the impact of the afternoon rest on blood pressure in people whose blood pressure is adequately controlled, the research team reports. Earlier, the team noted that the afternoon nap was associated with lower blood pressure and the use of fewer antihypertensive drugs in patients with very high blood pressure.
212 subjects were examined for the study
"The higher the blood pressure, the more pronounced the effort to lower blood pressure.To include people with relatively well controlled blood pressure, we can have more confidence that there will be significant differences in blood pressure levels due to sleep in the afternoon, "explains Kallistratos. For the study, 212 subjects with an average blood pressure of 129.9 mmHg were examined. On average these participants were 62 years old and just over half were female. About one in four subjects had smoker and / or had type 2 diabetes. In their research, the doctors continuously evaluated and recorded blood pressure, the afternoon sleep time (the average duration was 49 minutes), the lifestyle habits (eg alcohol, coffee and salt consumption, physical activity) and the so-called pulse wave speed for 24 hours. a measure of stiffness in the blood vessels. The participants wore an ambulatory blood pressure monitor to measure and monitor blood pressure at regular intervals during their daily lives. In addition, an echocardiogram, an ultrasound of the heart, was performed during the study. (As)
