Can longer and better sleep improve high blood pressure?

A report published via MayoClinic Hypertension suggests that prolonged sleep deprivation increases the chances of raised blood pressure (hypertension).

Researchers analysed the results of under five thousand participants, who were between the ages of 33 and 85 years old.

Among participants at the younger end of the range, those who slept for less than 6 hours each night had more than twice the chances of increased blood pressure than those who slept seven or more hours per night. This was not significant in those older than 59 years.

Early studies linked less sleep with cardiovascular disease however it was unclear if sleep deprivation could also affect blood pressure in people who didn't have a sleep disorder.

Better sleep clearly reduces the incidence of raised blood pressure and various methods are suggested to promote this including reviewing the bedroom environment, window coverings, tranquility and bedding:-

• Fresh Air - an open window helps oxygenate the brain for deeper sleep.
• Use heavy curtains or effective blinds to keep the room properly dark.
  
• Quality bedding - the bedding you has an effect on the quality of sleep. Studies show that better quality bedding sets and duvet covers not only help relax but also maintain a constant comfortable temperature
• Avoid caffeine for several hours before bed-time
  

The researchers commented in this study study that people who sleep for short spells — below six hours a night — increase their daily average blood pressure and heart rate. Over time it is concluded, this may lead to continued high blood pressure.

Of course further studies are needed to better understand the role of sleep deprivation in high blood pressure.

But this preliminary study suggests that increasing the amount and quality of sleep may play a role in the treatment and prevention of high blood pressure.
