Why should we wear cotton clothes in summer?
Show answer & explanation
Correct answer: C
Explanation
Correct Answer: Option 3 (Cotton clothing absorbs sweat and helps it evaporate, keeping the body cool.)
Explanation:
Our bodies sweat more in the summer. Cotton is a good water absorbent. It absorbs sweat and exposes it to the atmosphere, allowing it to evaporate easily. Latent heat is released from the body during the evaporation process, resulting in a feeling of coolness.
Additional Facts
Porous Structure: Cotton fabrics have tiny pores that help with air circulation.
Synthetic Fabrics: Fabrics like nylon or polyester do not absorb sweat, which can make the skin feel sticky and increase body temperature.
White Color: Light-colored cotton clothing is more comfortable in the summer because it reflects the sun's heat.
