Bad sleep ups blood pressure risk
According to BBC News, researchers say they would expect a similar effect in women.
The British Heart Foundation said it was important for everyone to prioritise sleep.
High blood pressure - also known as hypertension - increases the risk of heart attack, stroke and other health problems.
Researchers measured the "sleep quality" of 784 men over the age of 65 between 2007 and 2009. At the start none had hypertension, while 243 had the condition by the end of the study.
The patients were split into groups based on the percentage of time asleep spent in deep, or slow wave, sleep. Those in the lowest group - 4% deep sleep - had a 1.83-fold increased risk of hypertension compared with those in the highest group, who spent 17% of the night in deep sleep.
