1. Isometric handgrip exercises. An American Heart Association study found that squeezing a spring-loaded handgrip for two minutes, over a period of 12 to 15 minutes three times a week, can help lower blood pressure. Why? The study found that blood flow returns to your hands after the isometric exercise, improving blood vessel function. Another study reported in the journal Hypertension found this exercise produced a 10% drop in both systolic (top number) and diastolic (bottom number) readings when practiced six times a day, five days a week for four weeks.

Initially, these medications were only recommended for people whose blood pressure exceeded 160/100 mmHg, but they are now routinely prescribed when blood pressure approaches 140/90 mmHg, even in the absence of any previous cardiovascular event. Treating mild hypertension with drugs has not been shown to be effective, yet it is common practice (3, 4).
Heart damage leads to coronary artery disease, the narrowing of arteries that supply blood pressure to your heart. Overtime coronary artery disease leads to heart attacks and irregular heart rhythms. Damage to your heart could lead to an enlarged heart caused by forcing your heart to work harder than normal, leading to heart attack and sudden cardiac death. And lastly damage to your heart leads to heart 
A lack of vitamin D is common in developed countries and can cause a range of health problems. But this simple and inexpensive supplement may reduce the risk of cardiovascular disease. Taking around 4000IU of a high-quality D3 supplement daily can also support bone health, lower blood pressure, boost your mood and reduce fatigue – and these are just a few of its many health benefits.

Cayenne Pepper is probably the fastest way to lower high blood pressure. Cayenne pepper is a powerful vasodilator, which means it helps expand blood vessels and improve blood flow. This effect naturally lowers blood pressure levels by increasing the rate at which blood flows throughout the circulatory system, which in turn takes some of the pressure off arterial walls. Either mix one teaspoon of cayenne pepper with half a cup of lukewarm water or mix two tablespoons of raw organic honey with two teaspoons of cayenne pepper; boil them with eight ounces of water and drink when it is warm. A side note: Be careful how many Scoville Units your cayenne pepper is. I bought mine, 90,000 Scoville Units, and OMG. I thought I was going to breathe fire.
The American Health Association actually looked at different kinds of meditation techniques ranging from focussed attention to Transcendental meditation (TM), and contemplative forms like Zen and mindfulness techniques. Out of these, TM was found to have a modest effect on blood pressure reduction, but whether it is superior to other techniques is hard to say since head-to-head trials have not taken place.
Sleep. Short and poor-quality sleep are both associated with raised blood pressure (40). On the other side of the spectrum, excessively long sleep may also be harmful. One study found increased blood pressure in those who got fewer than five hours of sleep per night and in those who averaged more than nine hours of sleep per night, when compared with people who slept around seven hours (41). I suspect that it’s not the long sleep itself that is the problem, but that some underlying condition is both increasing sleep requirement and raising blood pressure.
