A lack of deep sleep may contribute to high blood pressure.  A study done on older men found that those who reported having less deep sleep were 80% more likely to develop high blood pressure.  Several factors may contribute to lowering the amount of deep sleep a person has. These may include having sleep apnea, taking medications that interfere with sleep or having other health issues that inhibit good rest (such as frequent awakening and having to get up often at night).

Deep sleep is the type of sleep known as a “slow wave” sleep that allows the body to restore its energy reserves. During slow wave sleep blood pressure goes down, breathing slows and the heart rate drops. People usually fall into a deep sleep in the early part of the night.

It is believed that the connection between lack of deep sleep and high blood pressure is that if blood pressure does not drop significantly during sleep damage to the blood vessels may occur.  Too little deep sleep may also cause the brain to release fewer hormones and other substances that the body needs to maintain proper blood pressure.

It is known that being active and having adequate exercise increases the likelihood of a person being able to sleep deeply. In addition if medications interfere with sleep, they can be replaced with an alternate medication without such a side effect. It is important to reduce high blood pressure to normal limits to reduce the risk of heart disease and other illnesses.

    Sometimes you hear about people falling to sleep with their tv on. I wonder if this interferes with Slow wave or Deep sleep?

    High blood pressure is a condition caused by increased pressure in the blood vessels. Blood pressure is caused by the pressure exerted by blood on the arterial walls due to the pumping action of the blood flowing through them. The normal blood pressure of a person should be 120/80 mm of Hg.
