The University of Warwick led research team looked at data from "The Whitehall II Cohort" which studied volunteers from 20 London-based civil service departments. There were a total of 6,592 participants (4,199 men and 1,567 women). The Warwick team defined hypertension as blood pressure equal to or higher than 140/90 mm Hg or if the subject made regular use of antihypertensive medications.
The researchers found that the those women in the study group who slept less than or equal to 5 hours a night were twice as likely to suffer from hypertension than women who slept for the more recommended seven hours or more a night. The researchers found no difference between men sleeping less than 5 hours and those sleeping 7 hours or more.
I wonder if the difference is due a difference in how male and female bodies react to sleep deficits. Or maybe the conditions that cause women to sleep less are different than the conditions that make men sleep less. Maybe stressful environments cause women to miss sleep but for men maybe the sleep is missed due to the desire to do more activities that are less stressful. Mind you, that's pure speculation. More likely female bodies react to lack of sleep in ways that do more damage to blood vessels.
Whether you are a man or women there are plenty of scientific reasons why you should get enough sleep. See my previous posts Less Sleep Increases Obesity, Sleep A Lot To Avoid Burn-Out From Stress And To Stay Skinny, and Lack Of Sleep Suppresses Neurogenesis And Memory Formation. Sleep is good.
