If you already have high blood pressure, home monitoring can let you know if your fitness routine is helping to lower your blood pressure, and may make it so you don't need to visit your doctor to have your blood pressure checked as often. Home blood pressure monitoring isn't a substitute for visits to your doctor, and home blood pressure monitors may have some limitations.
One drink counts as 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of spirits. "High levels of alcohol are clearly detrimental," says Obarzanek. "But moderate alcohol is protective of the heart. If you are going to drink, drink moderately." (And if you're trying to keep your weight in check, stick to these low-calorie alcoholic drinks recommended by registered dietitians.)
Some research on watermelon extract and high blood pressure suggests the amino acid citrulline found in the fruit may help manage high blood pressure. One study found those who took watermelon extract showed reduced blood pressure specifically in the ankles and arm arteries. Other studies on mice also show watermelon’s positive effect. Although more research is needed to determine the specifics, eating fruit like watermelon isn’t going to hurt.
Omega-3 fats are typically found in flaxseed oil, walnut oil and fish, with fish being by far the best source. Unfortunately, most fresh fish today contains dangerously high levels of mercury. Your best bet is to find a safe source of fish, or if this proves too difficult, supplement with a high quality krill oil, which has been found to be 48 times more potent than fish oil.
Exercise can also lead to lower blood pressure. Although performing moderate to vigorous exercise leads to higher blood pressure during activity, it is lowered afterwards. A wealth of studies indicate that getting 150 minutes per week of exercise—whether walking, cycling, gardening, dancing, or weights—can lead to significant drops in blood pressure over time. Try to exercise every day, but even three or four times per week can bring on big improvements.
