Rule 1: Eat healthily

A healthy diet is a balanced diet. Different nutrients help our body systems.
Iron helps blood carry oxygen around the body.
Potassium helps your heart, muscles and nerves work properly. It also helps prevent high blood pressure.
Vitamin C helps strengthen your immune system.
Proteins build muscle and help us grow.
Carbohydrates provide fibre, which helps move food through the digestive system, keeping it clean and running smoothly.
Remember to drink plenty of water. Water keeps the body systems functioning properly.

Rule 2: Exercise

It is very important to do exercise regularly. Exercise makes our body stronger and it also helps our circulatory and respiratory systems. When we exercise, we breathe faster and our heart has to work harder to pump blood around the body. As a result, our heart gets stronger. The muscles that we use to breathe in and out also get stronger.

Rule 3: Sleep

It is very important that we get enough sleep.
Sleep allows our bodies to rest and grow. Sleep also helps the brain develop so that speech and memory function properly the next day.

Rule 4: Keep clean

We wash our body to remove dirt, bacteria and sweat. We should wash our hands before we eat and after going to the toilet to remove any germs. We also need to remove food and plaque from our teeth by brushing them at least twice a day.

Rule 5: Have medical check-ups

Medical check-ups monitor our health and check that our body systems are working properly. Your doctor will also make sure you have the vaccinations you need to protect you from certain diseases. It is a good idea to have regular check-ups with your dentist and optician too.
