A new study finds older men who do not get enough deep sleep are nearly twice as likely to develop high blood pressure.
Researchers measured the sleep patterns of nearly 800 men with an average age of 75.
They discovered, those who spent less than four per cent of their time sleeping in a deep sleep, were 80 per cent more likely to develop hypertension.
They also generally suffered from shorter sleep duration, waking more at night, and more severe sleep apnea.
The findings are reported in the American Heart Association Journal, “hypertension.”
