The Relationship Between Blood Pressure and Sodium The Relationship Between Blood Pressure and Sodium

What is high blood pressure?

Hypertension, or high blood pressure, occurs when there is too much force on your arteries as your heart beats.

Blood pressure is typically read as systolic blood pressure (the pressure when your heart muscles contract) over diastolic pressure (the pressure when your heart is refilling with blood). A blood pressure reading might look something like 120/80mmHg. When the top number (systolic) is over 140mmHg, or the bottom number (diastolic) is over 90 for an extended period of time, it may indicate that you have high blood pressure.

What causes high blood pressure?

There is no one thing that causes high blood pressure. In fact, most cases of high blood pressure have no clear cause.  However, there are many factors that can contribute to high blood pressure. Blood pressure may occur from obesity, frequent stress and anxiety, excessive alcohol consumption, smoking, and too much salt in the diet. Some groups of people are predisposed to having high blood pressure like older adults, African Americans, individuals with diabetes, and individuals with a family history of high blood pressure are at a higher risk for high blood pressure.  In other cases, another medical condition or medicine can cause high blood pressure.


Sodium – How Much to Get?

For the average American, the recommendations for sodium intake is 2,300mg per day.

Sodium recommendations are lower for individuals who are:

Americans typically eat well above the recommended 2,300mg at about 3,400mg of sodium per day. Reducing sodium intake can reduce blood pressure and risk for other diseases. Talk to your doctor about specific recommendations for how much sodium is right for you.

Stress Management

Meditation

Meditating is a quick and easy thing you can do at any time. Meditating twice a day can help reduce stress, blood pressure and additional risks of other heart diseases. Start your meditation off small, by meditating for 5 minutes twice a day and work your way up to 20-minute sessions twice per day.

Three easy steps to get started:

  1. Find a quiet room
  2. Sit in a posture that is comfortable to you
  3. Close your eyes and focus on your breathing

Exercise

Physical activity is not only good for maintaining weight, but it is also great for managing stress! Exercise releases hormones in your body that make you feel better. For adults, it is recommended to get 150 minutes of exercise per week. Check out our previous post for more info on the importance of physical activity.

Social Support

When you’re feeling stressed out, don’t keep it bottled inside. Turn to your friends and family


Other Ways to Control Blood Pressure

Weight Loss

Losing even a little bit of weight can reduce blood pressure and/or prevent high blood pressure in overweight people. To achieve this health benefit, a weight loss of 5-10% of your total body weight, or about 10 pounds, is needed.

Eating a Diet Full of Fruits and Vegetables

Eating fruits and vegetables has been associated with lowering blood pressure, and a lower risk of hypertension. Meal patterns like the DASH diet have been shown to reduce blood pressure significantly. The DASH diet recommends that individuals on a 2,000 calorie diet eat 4-5 servings of vegetables, and 4-5 servings of fruits every day. What’s in a serving?

Monitor Your Blood Pressure

Self-monitoring is a great way to keep your health goals on track. Some grocery stores have machines to measure blood pressure for free, or you can purchase an at-home machine to check your blood pressure.

Go to the Doctor

It is important to visit your doctor on a regular basis if you have hypertension and take your medications as needed. Your physician can also refer you to other services that can help you manage your blood pressure.
