Unit 3

A Healthy Body

Our body is a wonderful machine. It is made up of many parts. Each part has a special job to do. All body parts work together so that the body functions properly. It is very important that we take care of our bodies.

✨ To stay healthy:

Eat a balanced diet for the proper growth of the body.
Exercise daily to keep all the parts of the body in good working order.
Rest to get the energy that you have used up back.
Wash and keep yourself clean so that you do not contract a disease or become ill.

🥗 Healthy eating:

You need food to stay alive and healthy. Growing children need a lot of proteins. Proteins are found in meat, milk, eggs, fish, and beans. Fresh fruits and vegetables are also very beneficial.

You should eat food at regular intervals.
You should not stay hungry for a long time.

Exercising & Keeping Clean

🚴 Exercising:

Regular exercise keeps your body strong and fit. Being physically active can improve your mental health, assist in weight management, lower your risk of disease, strengthen your bones and muscles, and enhance your ability to do everyday activities. Cycling, walking, and swimming are the best exercises to do.

🧼 Keeping clean:

You must keep your body clean. Washing and bathing keep your body free from dirt. It also stops you from getting skin diseases.

Household trash should be kept in a covered bin, and drains around your house should also always be covered.

How do you become ill?

You become ill when you catch a disease from someone or something.

Many diseases are caused by tiny living things. We call them germs. Bacteria and viruses are germs. When germs attack the body, we become ill.

Sometimes, larger animals such as worms live inside our bodies. They also make us ill.

🦠 Bacteria:

Bacteria are so small that we cannot see them. They can only be seen through a microscope. Bacteria cause diseases such as cholera, typhoid, sore throat, etc.

👾 Viruses:

Viruses are very small. They are much smaller than bacteria. They live inside the cells of our bodies. They are responsible for diseases such as the common cold, influenza, measles, chickenpox, etc.

Unit 3

How Germs Enter & Protection

🤧 How germs enter our bodies:

Germs enter our bodies in many ways.

When people cough or sneeze, germs from their bodies are pushed out into the air. When we breathe in the same air, germs enter our bodies. They attack the cells of the body and make us ill.

We can catch diseases if we touch people who have these diseases, or if we use the things that they have used, such as their cups, towels, combs, etc.

🛡️ Protecting the body against diseases:

If we know how germs spread, we can protect ourselves from them. The important things to remember to protect your family and yourself from diseases are:

Always wash your hands with soap and water before touching food.
Wash fruits and vegetables before eating them.
Always wash your hands after using the toilet.
Keep food covered to protect it from flies.
Do not let your pet lick your face or eat from your plate.
If you have a disease that can spread, stay away from people until you are better.
Cover your mouth with a handkerchief when you cough or sneeze.
