What do you do if your heart rate is high

Exercise is an important part of disease prevention – and that includes cancer prevention, too. But not all exercise is created equal. It’s essential that some of your exercise make your heart beat faster than it does when you’re resting.

Getting your heart to beat faster trains your body to move oxygen and blood to your muscles more efficiently, helps you burn more calories and lowers your cholesterol. All of this can help you stay healthy and lower your cancer risk.

According to the American Institute for Cancer Research, 150 minutes of moderate physical activity or 75 minutes of vigorous exercise each week can help lower your cancer risk. It’s the vigorous exercises that can help you get your heart rate up.

How to measure your heart rate

So, how do you determine your heart rate? One of the easiest ways to measure your heart rate is with a monitor, says Whittney Thoman, exercise physiologist at MD Anderson’s Cancer Prevention Center. This is typically a watch or a strap that goes around your arm or chest that syncs with a watch or another device. Many wearable fitness trackers now include heart rate monitors.

If you don’t have a heart rate monitor you can check your heart rate using your pulse.  To find your pulse, use two fingers (your middle and your index fingers) to find your carotid artery, just below your esophagus or throat. Then, count the beats you feel for 10 seconds. Multiply that number by six. That’s roughly the number your heart beats per minute.

Understanding your heart rate

Now that you know how to measure your heart rate, you can determine:

  • Active heart rate: how fast your heart beats when you’re active or exercising
  • Resting heart rate: how fast your heart beats when you’re resting or relaxing
  • Maximum heart rate: the highest rate your heart can obtain during activity. To find your maximum heart rate, subtract your age from 220. For example, if you’re 40 years old, subtract 40 from 220 to get a maximum heart rate of 175. This is the maximum number of beats your heart is capable of per minute, but you should not try to exercise to this level.

Check your pulse or your heart rate monitor while you’re resting and then again while you’re exercising to compare your resting heart rate to your active heart rate.

If you’re working at 50 to 70% of your maximum heart rate, then that exercise is considered moderate. If you’re working at 70 to 85% of your heart rate then its vigorous exercise. If your heart is working harder than that (above 85%) it could be dangerous, so be sure to back off or consult your doctor.

If you’re worried about an increased heart rate causing other health problems or have had heart problems in the past, talk to your doctor before you begin exercising at a higher intensity.

Ways to get your heart rate up

Now that you know how to determine your heart rate, the next step is to find exercises that will help boost it to improve your health. Here are a few ways to get your heart rate up.

  • Set an incline. If you’re on the treadmill increase the incline. Or if you’re walking outside look for hills. This will challenge your muscles and help increase your heart rate.
  • Take the stairs. Just like adding an incline, stairs bring a new challenge to your workout.
  • Alter your pace. Whether you’re walking, riding a bike, swimming or practicing yoga, you don’t have to increase your pace for the entire workout. Add in short bursts of increased effort at a faster pace. Over time, you’ll be able to increase the duration of these bursts.
  • Take shorter breaks. If you’re doing an interval workout or lifting weights, take shorter breaks in between the different exercises.

If your heart is racing as you’re sitting reading this article, it’s possible your body is trying to tell you something. A high resting heart rate, or a heart rate of more than 100 beats per minute, means your heart is working extra hard to pump blood through your body. And, that extra effort could result in a wide range of negative effects on your overall health, including feelings of dizziness and fatigue – and most seriously – blood clots, heart failure and, in rare cases, sudden death.

Normal resting heart rate is anywhere between 60 and 100 beats per minute, and it’s simple to check how fast yours is beating. While idle, hold your pointer and middle finger between your bone and tendon on the thumb side on your wrist until you feel your pulse, and count the number of beats for a minute – that is your resting heart rate.

Certain aspects of someone’s resting heart rate are directly connected to uncontrollable factors, such as age and genetics, however there are certain actions that be taken to help decrease heart rate and improve overall wellbeing for those whose resting heart rate is above normal.

Here are six proven ways to lower your resting heart rate:

1. Stay Out of the Heat:

The warmer the temperature, the faster your heart beats. This is because your heart is working quickly to pump blood to the surface of your skin, produce sweat and cool off the body. To ensure your heart isn’t beating on overdrive, stay in cool, comfortable places when possible and remember to stay well hydrated.

2. Exercise Frequently: 

Exercise is great for your health for many reasons – and securing a normal resting heart rate is one of them. While it might seem counterintuitive since your heart rate increases while you’re exercising, what you’re actually doing every time you’re working out is training your heart to be stronger and more efficient at pumping blood. Then, when you’re in rest mode, your heart is more easily able to maintain a normal heart rate.

3. Add More Fish to Your Diet: 

Similarly to exercising, maintaining a healthy diet is beneficial to each of us for many reasons. For one, incorporating more fish has been associated with lower resting heart rates, according to a study from the American Heart Association. Don’t enjoy eating fish? Talk a doctor about taking fish oil supplements, which may have positive effects on heart rate as well.

4. Lessen the Stress: 

The higher our stress level, the higher our heart rates. For many people, stress can feel inevitable. Perhaps you’re trying to balance work and home life, but can never seem to find enough time to get it all accomplished. A quick and simple way to begin to de-stress is to designate a block of time each day to disconnect from your cell phone and other electronic devices. This frees up time to be productive and gives you an opportunity to declutter your mind and reprioritize. Another simple de-stressing tip is to practice meditation to relax the mind.

5. Be Mindful of Your Breathing: 

On the topic of medication, another quick and easy way to lower your heart rate is to practice mindful breathing exercises. Inhale slowly for five seconds and then exhale slowly for 15 seconds. Try dedicating five minutes to this each day.

6. Nix the Cigarettes: 

It might come as no surprise that smoking cigarettes has countless negative effects on a person’s health. According to the Center for Disease Control and Prevention, this includes an increased risk for coronary heart disease, stroke and lung and other cancers. Additionally, tobacco products have been shown to increase resting heart rates. When your body consumes nicotine, your veins and arteries constrict, and your heart has to then put in that extra work to pump blood. If you’re a smoker, the good news is quitting can decrease your resting heart rate within just 24 hours – so the sooner you can nix the cigarettes – the sooner you’ll begin to see results.

How can I quickly lower my heart rate?

Close your mouth and nose and raise the pressure in your chest, like you're stifling a sneeze.” Breathe in for 5-8 seconds, hold that breath for 3-5 seconds, then exhale slowly. Repeat several times. Raising your aortic pressure in this way will lower your heart rate.

What is dangerously high for heart rate?

Tachycardia refers to a heart rate that's too fast. How that's defined may depend on your age and physical condition. Generally speaking, for adults, a heart rate of more than 100 beats per minute (BPM) is considered too fast.

At what heart rate should you go to the hospital?

If you're sitting down and feeling calm, your heart shouldn't beat more than about 100 times per minute. A heartbeat that's faster than this, also called tachycardia, is a reason to come to the emergency department and get checked out. We often see patients whose hearts are beating 160 beats per minute or more.

Why my heart rate is very high?

Stress, exercise, or even too much alcohol or caffeine can cause your heart to beat faster than normal. But if your heart races a lot—or if you notice your heartbeat is often irregular—then you should see a doctor.
