Class 2 EVS health and habits

Knowing basic cleanliness and healthy habits.

Staying Healthy and Happy — Class 3 EVS (CBSE)

From the current NCERT Our Wondrous World Grade 3 book, Unit 3: Gifts of Nature, Chapter 9. Good health is a treasure — for both our body and our mind.

1. Why this chapter matters

Being healthy is not only about the body; a happy mind matters too. Learning good habits of cleanliness, food, exercise, and rest, and spending time with family and friends, helps children stay fit and cheerful.

2. Key ideas

Cleanliness (hygiene): brush teeth twice a day, bathe daily, wash hands before eating and after using the toilet, cut nails, and wear clean clothes.
Healthy food: eat fresh, balanced meals and drink clean water.
Exercise and play: run, play games, and stay active to keep the body fit.
Rest and sleep: get enough sleep so the body can rest and grow.
A happy mind: spend time with family and friends, share, help others, and do things you enjoy.
Good health means a healthy body and a happy mind together.

3. Let's understand

To keep our body healthy, we follow simple habits every day. We brush our teeth, bathe, wash our hands before eating and after the toilet, cut our nails, and wear clean clothes. We eat fresh, healthy food and drink clean water.

Our body also needs exercise — running, playing, and moving keep us strong. And it needs rest; enough sleep helps us grow and feel fresh.

But health is not only about the body. A happy mind is just as important. Spending time with family and friends, sharing, helping others, and doing things we enjoy make us feel good inside. When the body is healthy and the mind is happy, we are truly well.

4. New words

Word	Meaning
hygiene	keeping ourselves clean to stay healthy
exercise	moving the body to keep it fit
rest	a break to let the body relax
habit	something we do regularly
healthy	fit and well in body and mind

5. Activity corner

Make a "My Healthy Day" chart. Write one thing you will do for each:

Cleanliness (a hygiene habit)
Food (a healthy choice)
Exercise (a game or activity)
Happiness (time with family or a friend)

6. Common mistakes

Mistake: Thinking health means only not being sick. Fix: Health means a healthy body and a happy mind.
Mistake: Skipping handwashing or brushing. Fix: Wash hands before eating and brush teeth twice a day.
Mistake: Thinking only food keeps us healthy. Fix: We also need cleanliness, exercise, rest, and happiness.

7. Let Us Think

Write three habits that keep our body clean. Brushing teeth, bathing daily, and washing hands (also cutting nails, wearing clean clothes).
Why do we need exercise and sleep? Exercise keeps the body fit; sleep lets the body rest and grow.
When should we wash our hands? Before eating and after using the toilet.
What keeps our mind happy? Spending time with family and friends, sharing, helping, and doing things we enjoy.
What does good health mean? A healthy body and a happy mind together.

8. Answer key

Brushing teeth, bathing, washing hands.
Exercise keeps us fit; sleep helps us rest and grow.
Before eating and after using the toilet.
Time with family and friends, sharing, and helping.
A healthy body and a happy mind.

9. Quick revision

Cleanliness: brush, bathe, wash hands, cut nails, clean clothes.
Eat fresh healthy food and drink clean water.
Exercise and play keep the body fit; sleep helps it rest.
A happy mind comes from family, friends, sharing, and helping.
Good health = healthy body + happy mind.
