Can Lack of Sleep lead to High Blood Pressure?

Can Lack of Sleep lead to High Blood Pressure?

Answer: Possibly. It’s thought that sleeping less than six hours a night could be linked to increased blood pressure.

People who sleep five hours or less a night may be at higher risk of developing high blood pressure or worsening already high blood pressure. There’s also an increased risk of high blood pressure for people who sleep between five and six hours a night, although that risk is not as high as it is for people who sleep five hours or less a night.

It’s thought that sleep helps your blood regulate stress hormones and helps your nervous system remain healthy. Over time, a lack of sleep could hurt your body’s ability to regulate stress hormones, leading to high blood pressure.

Sleeping seven to eight hours a night may play a role in the treatment and prevention of high blood pressure. Talk to your doctor for tips on getting better sleep, especially if you have high blood pressure.

Nitric Oxide: The New Hero of Human Biology

Twenty minutes on a treadmill will certainly help you fit into that one-size-too-small dress. But new research suggests that exercise may also help increase the production of nitric oxide, a substance that does a variety of important jobs in the body, perhaps none more valuable than to help prevent heart disease.

“Nitric oxide does a variety of jobs,” explains Dr. Jason Allen of Duke University. “It tends to be antiatherogenic, which means that it helps prevent your arteries from becoming clogged. From start to finish, this is a 40-year process which depends on lifestyle.” That is, it’s a function of what you eat, how you exercise, and the stresses you are under.
