Question 41-45
To stay healthy, adults should try to be active every day and aim to achieve at least 150 minutes of physical activity over a week through a variety of activities.
For most people, the easiest way to get moving is to make activity part of everyday life, like walking or cycling instead of using the car to get around. However, the more you do, the better, and taking part in activities such as sports and exercise will make you even healthier.
For any type of activity to benefit your health, you need to be moving quickly enough to raise your heart rate, breathe faster, and feel warmer. This level of effort is called moderate intensity activity. If you’re working at a moderate intensity you should still be able to talk but you won’t be able to sing the words to a song.
An activity where you have to work even harder is called vigorous intensity activity. There is substantial evidence that vigorous activity can bring health benefits over and above that of moderate activity. You can tell when it’s vigorous activity because you’re breathing hard and fast, and your heart rate has gone up quite a bit. If you’re working at this level, you won’t be able to say more than a few words without pausing for a breath. People are less active nowadays, partly because technology has made our lives easier. We drive cars or take public transport. Machines wash our clothes. We entertain ourselves in front of a TV or computer screen. Fewer people are doing manual work, and most of US have jobs that involve little physical effort. Work, household chores, shopping, and other necessary activities are far less demanding than for previous generations.
We move around less and burn off less energy than people used to. Research suggests that many adults spend more than 7 hours a day sitting down, at work, on transport or in their leisure time. People aged over 65 spend 10 hours or more each day sitting or lying down, making them the most sedentary age group.
Adults should try to achieve at least 2.5 hours of physical activity over a week to stay healthy.
