Get moving!
The more time you spend in front of the television or playing video games, the less time you have to be active. Not being active is called sedentary (say: sed-un-tair-ee). Leading a sedentary lifestyle can cause weight gain and even obesity (dangerously high weight), which can lead to type 2 diabetes, high cholesterol levels, and high blood pressure. These three health issues can hurt your heart and make it easier for you to get certain diseases. Make physical activity a regular part of your life. It can help you protect your health!
How do you know if your weight is at an unhealthy level or if you are dealing with obesity? You can measure your Body Mass Index (BMI). Use the girlshealth.gov calculator to find out what your BMI is.
