On Sunday April 7th, we mark the 65th anniversary of the World Health Organization (WHO). Each year, WHO uses the occasion to highlight a particular health issue; this year, they chose high blood pressure—hypertension. It’s a timely choice. Worldwide, at least one in three adults suffers from high blood pressure. That amounts to 68 million adults in the U.S. alone.

Your blood pressure naturally rises and falls a bit during the day, but permanent high blood pressure is a dangerous condition that increases your chance of heart disease, heart attacks, strokes, kidney failure, and even blindness.
