0 Your body is built to move: running, climbing and jumping make the heart and lungs stronger, build muscle and bone, and even help you sleep, think and feel happier. 1 When you run, your muscles need more oxygen, so you breathe faster and your heart pounds: that is your body doing its job, not a sign something is wrong. 2 It doesn't have to be sport: a game of tag, a bike ride, a walk to school, a swim or dancing in the kitchen all count towards the hour a day children are advised to move. 3 Bodies like change more than perfection: slouching for a while does no harm, but sitting in any one position for hours does, so get up, stretch and move often. 4 UK guidance says children and young people should be active for an average of at least 60 minutes a day across the week. 5 Activity makes the heart, lungs, muscles and bones stronger, and helps sleep, mood and concentration. 6 Breathing faster during exercise is normal, because the muscles need more oxygen, and fitness builds up gradually. 7 A heavy bag on one shoulder can strain the back and shoulders, so use both straps and pack only what you need; it rarely causes lasting damage. 8 There is no single perfect posture; changing position often and getting up to move about every half hour is good for the body. 9 A stitch is a sharp pain in the side during exercise, its exact cause is still not known for certain, it isn't dangerous, and slowing down and breathing deeply helps. 10 A big meal or a lot of drink just before running makes a stitch more likely. 11 A warm-up gets the blood flowing and prepares muscles and joints, but stretching alone doesn't prevent every injury. 12 Muscle soreness a day or two after unusual exercise is normal as muscles adapt, and gentle movement helps. 13 Swimming is great exercise and a lifesaving skill, and in England primary schools aim for every child to swim at least 25 metres; people can learn to swim at any age. 14 Exercise releases chemicals in the brain that lift mood and reduce stress, so it isn't only about weight. 15 Walking or cycling to school adds activity and is better for the air than a short car trip. ← previous Being in hospital, and a sick parent or grandparentnext → Screens, eyes and sleep↑ back to Medicine This page in Markdown → https://md.mova.elamur.ai/free/en/corpora/school/medicine/34-exercise-and-posture/
