प्रश्न
What type of clothes should we wear in summer ? Why ?
उत्तर
In summer, we should wear cotton clothes or white clothes because cotton absorbs sweat easily and exposes it to the air for evaporation. Evaporation of this sweat keeps our body cool. In addition, white colour reflects sunlight, keeping the heat away from the body.
