You may have heard of "stress tests". A heart stress test helps doctors learn about how the heart works under stress. Some heart problems are easier to uncover when the heart is beating fast during exercise. When doing the test, people usually walk on a treadmill(跑步机), while the doctor checks how fast their heart beats and some other things. Although you can't really study for a stress test, you can follow these tips to keep your heart healthy so that you won't need one.
Don't use tobacco(烟草). The harmful things in it won't do any good to your heart. So stay away from it, and you won't have one of the biggest causes of heart problems.
Get moving. Exercise for at least 30 minutes every day. It helps you stay at a healthy weight and you'll be less likely to get some other health problems that may
hurt your heart.
Eat healthily. Choose foods that are low in fat and salt. Your meals should be rich in fruit, vegetables and meats. And beans can help keep your heart strong.
▲ Talk to your doctor about what a healthy weight is for you and try to reach it. People who are overweight face a higher risk of health problems, which can harm your heart!
Go to the doctor. An apple a day keeps the doctor away, but health check-ups are also important, they will help you detect health problems early on. Take care of your heart today, and you'll thank yourself tomorrow for a healthier life!
