Let Us Begin!

Every morning, you put on your school uniform before leaving for school. On a cold winter day, you wear a sweater or a jacket. On a hot summer day, you wear light cotton clothes.

Have you ever wondered why we wear different clothes at different times? Let us find out!

Why Do We Wear Clothes?

We wear clothes for many important reasons:

1. Protection from weather: Clothes protect us from heat, cold, rain, and wind.

2. Protection from dirt and insects: Clothes keep our body safe from dust, germs, and insect bites.

3. Modesty: Clothes cover our body and help us look neat and decent.

4. Identity: Some clothes show what work a person does, like a doctor's white coat or a policeman's uniform.

Think about it: What would happen if you wore a thick woollen sweater on a hot summer day in Chennai?

Clothes for Different Seasons

Summer (hot)Light, thin, cotton clothesCotton kurta, half-sleeve shirt, frock, shorts
Winter (cold)Thick, warm, woollen clothesSweater, jacket, shawl, muffler, gloves, cap
Rainy seasonWaterproof clothesRaincoat, gumboots, umbrella

In summer, we wear cotton clothes because cotton absorbs sweat and keeps us cool. In winter, we wear woollen clothes because wool traps warm air and keeps us warm.

School: School uniform (shirt, trousers or skirt, tie, shoes)

Festivals and parties: Special clothes like saree, lehenga, kurta-pyjama, sherwani
