Year 6 Science: Rest, sleep and lifestyle
Part of the Year 6 Science diet, exercise, drugs and lifestyle chapter. Chapter overview · whole chapter on one page
Rest, sleep and lifestyle
A healthy lifestyle includes regular rest and sleep, exercise, a balanced diet, good personal hygiene and time to relax. Each part of it helps the body work well.
During sleep, the body repairs itself, and the brain sorts and stores what we have learned. Growing children need plenty of sleep.
The table shows what different parts of the body need from exercise, rest and lifestyle.
| Body part | What exercise, rest or lifestyle does |
|---|---|
| Heart | beats faster during exercise, and gets stronger with regular activity |
| Lungs | take in more air during exercise, to supply more oxygen |
| Muscles | become stronger and more able to move the body with regular exercise |
| Bones | become stronger with regular exercise that puts weight on them |
| Brain | needs sleep and rest to stay alert and to store what we learn |

Exam tip
Exam tip. When you describe lifestyle, name at least two parts of it, such as exercise and sleep, and link each to a body part.
Try it (with your teacher, or a grown-up at home). Keep a sleep and rest diary for three days with a grown-up. Write the time you went to bed and got up, and how you felt in the morning. Talk about what helps you to rest well, such as a calm evening and no screens before bed.
