The following article was first published on my Sleep Disorders blog on WebMD:
Do you have high blood pressure?
If so, your problem could be caused by too much or too little sleep!
Recent research at the Boston University School of Medicine found that people who were sleeping above or below the recommended hours of daily sleep have an increased risk for hypertension.
Dr. Daniel Gottlieb, MD, MPH studied the responses of 2,813 men and 3,097 women, aged 40 to 100 years, to a questionnaire on sleep habits. He discovered that, compared to people sleeping between 7 and 8 hours per night, those sleeping less than 6 and between 6 and 7 hours per night, as well as those sleeping between 8 and 9 and 9 or more hours per night, had an increased prevalence of hypertension.
