Hit the sack to help avoid hypertension. A recent study shows a relationship between short sleep duration and high blood pressure. Researchers analyzed data on 4,810 participants—ages 32 to 59—over 10 years. Those who got only five hours or less of sleep per night were move than twice as likely to develop hypertension than those snoozing the recommended seven to eight hours. However, more sleep than eight hours wasn’t a benefit.
Normally, your heart rate and blood pressure are lower during sleep. If deprived of slumber over a long period of time, the average work done by the heart increases, and that can lead to changes in the heart and blood vessels.
James E. Gangwisch, Ph.D., lead author of the study and postdoctoral fellow at the Columbia University Medical Center, says, “A good night’s sleep is very important for good health.”
