![]() ![]() Your choices from active areas of the pyramid should exceed your choices from the inactivity area. But general inactivity or sedentary living is harmful to your health. Some activities of daily living - such as studying, reading, and even a moderate amount of screen time - are appropriate. We all need to take time to recover from daily stresses and prepare for new challenges, so periods of rest and sleep are important for good health. Research shows that screen time results in inactivity and increases health risk. A recent survey of children and teens in the United States found that they watch TV for an average of nearly four hours a day! Sixty-eight percent of teens have a TV in their room, and of course many also spend screen time on computers, video games, movies, and cell phones, more than doubling the amount of time they spend watching a screen. Screen time refers to time spent in front of a TV, computer game, phone screen, or any other device that substitutes inactivity for activities from the pyramid. Just as you should do 60 minutes of physical activity each day, drawing from the five types of activity presented in the pyramid, you should also avoid the inactivity that is common among people who log too much "screen time" on a daily basis. This illustration emphasizes the fact that being sedentary, or inactive, poses a health risk. Just below the Physical Activity Pyramid (see figure 5.2) you'll notice pictures of a television set and a video game controller with an X over them. It is also associated with many of the health benefits of activity described in part 1 of this book, such as controlling your level of body fat, and is well suited for people of varying abilities. Moderate activity should account for some of this time each day (30 minutes a day is recommended for adults). National guidelines recommend 60 minutes of moderate to vigorous activity each day for teens. Some other sports can be either moderate or vigorous for example, shooting basketballs is typically a moderate activity, whereas playing a full-court game is vigorous. It also includes sports that are not vigorous, such as bowling and golf. It includes some activities of normal daily living (also called lifestyle activities), such as yardwork (for example, raking leaves or mowing the lawn) and housework (for example, mopping the floor). Ability to perform moderate to vigorously intense physical activity on a regular basis without getting too tired and having energy left over to handle physical and mental emergencies. Moderate activity involves exercise equal in intensity to brisk walking. Study with Quizlet and memorize flashcards containing terms like Exercise, Components of physical fitness. Moderate physical activity is the first step in the Physical Activity Pyramid, and it should be performed daily or nearly every day. ![]()
