Enough Sleep Lower Blood Pressure

Is it true that sleep deprivation can cause high blood pressure?

Answer From Francisco Lopez-Jimenez, M.D.

Possibly. Sleep experts recommend that adults get 7 to 8 hours of sleep each night. Getting less than six hours of sleep is known to be bad for overall health. Stress, jet lag, shift work and other sleep disturbances make it more likely to develop heart disease and risk factors for heart disease, including obesity and diabetes. A regular lack of sleep may lead to high blood pressure (hypertension) in children and adults. The less you sleep, the higher your blood pressure may go. People who sleep six hours or less may have steeper increases in blood pressure. If you already have high blood pressure, not sleeping well may make your blood pressure worse. It's thought that sleep helps the body control hormones needed to control stress and metabolism. Over time, a lack of sleep could cause swings in hormones. Hormone changes can lead to high blood pressure and other risk factors for heart disease. Don't try to make up for a lack of sleep with a lot of sleep. Too much sleep — although not as bad as too little sleep — can lead to high blood sugar and weight gain, which can affect heart health. Talk to your health care provider for tips on getting better sleep, especially if you have high blood pressure. One possible, treatable cause of lack of sleep contributing to high blood pressure is obstructive sleep apnea. This sleep disorder causes breathing to repeatedly stop and start during sleep. Talk with your care provider if you feel tired even after a full night's sleep, especially if you snore. Obstructive sleep apnea may be the cause. Obstructive sleep apnea can increase the risk of high blood pressure and other heart problems.

Frequently Asked Questions

When you're asleep your blood pressure is generally lower than while you're awake. This is totally normal and is known as nocturnal dipping. The drop in both your systolic (the top number) and diastolic (bottom number) blood pressure can be up to 20% lower than your readings in the day time.

What is the best sleeping position for high blood pressure? Sleeping on the left side is the best sleeping position for hypertension because it relieves blood pressure on blood vessels that return blood to the heart.

Blood pressures were then measured on 78 adult patients both with and without the pillow. When blood pressure was measured with the arm at heart level diastolic blood pressure was on average 5.5 mmHg lower compared with measurements performed without the pillow.

Raising the head of the bed decreases the amount of blood returning to the heart due to the effects of gravity. In this case, the decreased blood return to the heart may decrease blood pressure.

Sit quietly in a comfortable position and close your eyes. Relax your muscles, progressing from your feet to your calves, thighs, abdomen, and so on, up to your neck and face. Breathe slowly through your nose, silently saying your focus word, phrase, or prayer to yourself as you exhale.
