When blood pressure is high what do you do to bring it down?

relax, exercise, improve your diet, utilize stress management techniques, speak with your doctor (do you need medication), minimize salt intake and cured foods.

Eat potassium rich foods, avoid table salt, drink 2 liters of water daily, get 30 minutes continuous exercise daily. If that doesn't do it, you need to see a doctor for medications to bring it down.
High blood pressure over time causes terrible damage to the body's systems, all of them.

Go to the doctor. If you have high blood pressure the longer you go without medication the more damage you do to your heart.
Garlic is a natural blood thinner which can make
it easier on your heart but you should go to the doctor
because blood pressure medicine could save your life.

avoid salt, reduce stress, eat wisely.

good luck.
