Your body works better when you move it. Running, swimming, biking, and playing sports are all exercise. When you exercise regularly, your heart pumps blood more efficiently, your lungs take in more air, and your muscles grow stronger. These changes build up slowly, a little every day.
Diego jogs for twenty minutes most mornings before school. At first, he got tired quickly and had to stop and catch his breath. After a few months of jogging, his heart didn't have to work as hard to keep up, because exercise had made it stronger.
You already know a balanced diet includes different food groups. Adding one healthy food does not undo eating too much of another. Sugar feeds the germs that cause tooth decay. Taking in more energy than your body uses can lead to obesity. Too much saturated fat, found in foods such as butter and fatty meat, raises the risk of heart problems.
Smoking damages your lungs and raises heart disease risk. Your liver breaks down alcohol, and too much can damage it. Drug misuse can also harm your body and brain. Avoid tobacco, alcohol, and drug misuse. Use medicines only with a trusted adult following medical advice and the label.
Eating well, staying active, sleeping enough, and avoiding tobacco, alcohol, and drug misuse all work together to keep your body's systems healthy.

Care for your body each day
Daily care helps your body stay healthy throughout your life.
Choose fruit and vegetables, whole grains, and foods that supply protein. Sugar can damage teeth. Taking in more energy than you use may increase body fat. Excess saturated fat raises the risk of heart disease.
Water makes up most of your body. Your brain, muscles, and other parts need enough water to work properly.
Activity strengthens muscles and helps the heart and lungs. Running, swimming, cycling, or sports make your heart beat faster. Regular exercise trains it to pump blood more effectively.
During sleep, your body can rest, grow, and make repairs. Children your age generally need 9 to 12 hours each night. Too little sleep makes learning and thinking harder and can affect health.
Tobacco, alcohol, and misused drugs can damage the brain, heart, liver, and lungs. Take medicines with help from an adult you trust, according to medical advice and the label's instructions.
Eating an apple, spending active time outdoors, and keeping a regular bedtime are small habits that support health.
How harmful substances affect health
Substances can affect both your body and your brain. Tobacco, alcohol, and misused drugs may cause serious damage.
Tobacco smoke harms the lung structures that pass oxygen into the bloodstream. Breathing can become difficult. Smoking also strains the heart and increases the risk of cancer and heart disease.
Alcohol slows brain activity, affecting clear thinking, balance, and decisions. Drinking too much over time can injure the liver, which processes substances in your blood.
Misusing drugs can harm your brain and body and change what you feel or see. Many drugs can cause addiction, a strong urge to keep using them that is hard to control. Your body can also get used to a drug, making it difficult to stop.
Repeated harmful use can develop into a substance use disorder. Someone with this illness may continue using despite damage to their health or relationships with friends and family.
Children should avoid tobacco, alcohol, and drug misuse. Medicines can be helpful when an adult you trust supervises their use according to medical advice and the label's instructions.
Build healthy habits
Everyday choices help you build a healthy routine.
Include fruit and vegetables in meals, alongside whole grains. Choose water rather than sugary drinks. Varied, balanced meals provide energy and materials for growth.
Find ways to be active daily. Cycling, dancing, tag, and dog walks all count; a marathon is unnecessary. Regular activity strengthens your heart and lungs and supports muscle growth.
Sleep gives your body time for growth and repairs. It also helps your brain remember what you learned. A consistent bedtime can help you get enough rest.
Choose a goal you can check. You could plan to have one piece of fruit with lunch or spend 30 minutes playing outdoors. Specific, small goals are easier to follow and can become habits.
Care for your feelings too. Enjoy time with people you love, share how you feel, and make time for activities you enjoy. Physical and mental well-being both matter.
Find activity you enjoy
Physical fitness helps you work and play without tiring too quickly. Activity, food, water, and rest all contribute.
Aerobic activities raise your heartbeat. Examples include swimming, running, soccer, and skipping rope. They train the heart and lungs, which supply oxygen throughout your body. Regular exercise helps the heart pump blood more effectively.
Movement also strengthens bones and muscles. Climbing, jumping, and carrying a backpack can help build muscle strength.
Balanced meals supply energy for play and growth. Water supports the body's functions. Sleep gives tired muscles time to recover and repair.
Begin with activities you like and repeat them regularly. Fitness develops over time, so you do not need to tackle everything at once. Enjoyable exercise is easier to keep doing.
Food, activity, and rest
Your eating, activity, and sleep habits all help care for your body.
Eat varied foods, including fruit, vegetables, whole grains, and protein foods such as chicken, fish, eggs, and beans. These supply vitamins and energy. Sugar may contribute to cavities. Extra energy beyond what your body uses can increase body fat. Too much saturated fat raises heart disease risk.
Your heart is a muscle. Regular activity strengthens it and supports your health. About an hour of daily movement, such as cycling, swimming, or outdoor play, helps your muscles, lungs, and heart.
Sleep allows repairs throughout the body and helps the brain store learning. Children need enough sleep each night. Keeping bedtime consistent can help.
Using tobacco or alcohol, or misusing drugs, may injure the brain, heart, liver, and lungs. Use medicines with an adult you trust, following medical advice and the instructions on their labels.
