Summary
Chapter 9 of the Class 3 The World Around Us (EVS) NCERT textbook (Our Wondrous World), "Staying Healthy and Happy", teaches children simple daily habits for keeping their bodies and minds clean and healthy, including hygiene routines, outdoor play and exercise, safe play practices, and stranger safety.
- Daily Hygiene Habits — The chapter lists key hygiene habits children should follow every day, such as brushing teeth twice, washing hands with soap after using the toilet and coming home, taking a shower, trimming nails, and drinking 6 to 8 glasses of water. Children are encouraged to check whether they follow these routines and think about how to make them regular habits.
- Traditional and Eco-Friendly Cleaning — The chapter introduces the Indian tradition of datun, where twigs from neem, karanj, or babool trees are used to clean teeth, which is the origin of the modern toothbrush idea. It also shows children how to make an eco-friendly home cleaner using orange or lemon peels, white vinegar, and optional cloves or bay leaves.
- Exercise and Active Play — Exercise makes the heart work harder and better, and outdoor play like running, jumping, skipping rope, and games such as kabaddi, cricket, football, and basketball keeps the body fit. The chapter notes that the body needs three types of exercise: cardio-respiratory, muscle and bone strengthening, and flexibility.
- Playing Safely and Stranger Awareness — Children learn to identify safe places to play, such as parks and school grounds, and unsafe places like busy roads and rooftops without railings.
