Four Ways to Lower Your Blood Pressure Without Drugs

Up to 90 percent of high blood pressure cases are thought to be caused by lifestyle habits that constrict blood vessels.

When your blood vessels are constricted tightly, your heart must work much harder to keep your blood flowing, hence the higher blood pressure.

Increasing a compound in your blood known as nitric monoxide can help to open constricted blood vessels and lower your blood pressure. Four ways to increase nitric monoxide in your blood are:

Aerobic exercise
Taking a warm bath
Breathing in and out through one nostril (by closing the other nostril and your mouth)
Eating bitter melon, which is rich in amino acids and vitamin C
