You’re stressed
Did you know that stress can make your heart pound and blood pressure rise? In fact, unremitting stress throws your body into the “fight or flight” mode. A note to remember — heart rate and blood pressure aren’t the same thing, and they don’t always rise or fall in tandem. Chronic stress keeps you — and your heart — in a state of high alert, which increases your chances of having a heart attack or stroke, shares Pam R Taub, a board-certified cardiologist and associate professor of medicine at the University of California, San Diego.
You have diabetes or are on your way to getting it
Doctors aren’t clear on whether a high heart rate causes diabetes or if diabetes causes a high heart rate, but recent studies show that the two are unquestionably related. Often, says Taub, people who develop diabetes are less active and more likely to have coronary disease and high blood pressure, all of which strain the heart. And when your heart’s not happy, it can lead to other problems down the road. “There are a lot of studies that link higher heart rate, especially in patients with diabetes, to more adverse outcomes,” explains Taub.
8 things you didn’t know about caffeine
You’re not getting enough exercise
You know the phrase “use it or lose it”? It applies to your heart. It’s a muscle, and it needs exercise to perform at its optimal peak. “Inactivity and obesity often contribute to an elevated resting heart rate,” says Taub. Why? Because when you’re out of shape, your heart has to work harder to get your blood where it needs to go. Plus, the bigger you are, the more blood you need. More blood to pump equals more heart beats per minute. The flip side is that getting a lot of exercise can lower your resting heart rate. Serious athletes typically have resting heart rates that are lower than 60 bpm.
Drugs (including prescription ones) are messing with your numbers
Certain medications can reset your heart rate readings and give you a new normal. “Beta blockers and calcium channel blockers are the main ones that can lower a heart rate,” says Taub. Both relax your heart, which can slow it down. That’s not necessarily dangerous, but check with your doctor if you have any concerns. Caffeine, on the other hand, can ramp up a heartbeat in a hurry. It’s often found in headache medications, and it lurks in certain food and drinks, like tea and chocolate. “Some people are extremely sensitive to caffeine, so they drink a coffee or an energy drink, and they immediately get elevations of their heart rate,” says Taub. Cutting back should help.
You’re dehydrated or too hydrated
Minerals in your body with an electric charge are called electrolytes. If you drink too much water or not enough, it can throw off the ratio of electrolytes to water in your system, which messes with your body chemistry. “If your potassium, calcium, or magnesium levels are very low, that can induce arrhythmias [abnormal rhythms], which can manifest as a higher heart rate,” shares Taub. If you find your heart racing for no reason at all, make sure to grab a bottle of water immediately.
Your thyroid is under or overactive
Your thyroid — the butterfly-shaped organ in your neck — produces hormones that help your body function fittingly. If it’s not making enough, it means you have hypothyroidism, which could cause your heart rate to be low, says Taub. On the other hand, if it’s over performing and pumping out extra hormones, you have hyperthyroidism, which can raise your heart rate. Your doctor can test your thyroid function with a blood test. If you feel your thyroid is the culprit, book an appointment with your physician as soon as possible.
