Wearing cotton clothes in summer
During summer days we sweat more than usual which keeps us cool. Because the sweat evaporates by obtaining heat from our body and changes into vapour. The heat equivalent to latent heat of vaporaisation is being absorbed from the body that makes he body cool.
It is recommended to wear cotton clothes in summer due to the fact that cotton is good absorber of water that helps to absorb the sweat and brings it in contact to the surrounding atmosphere for easy evaporation.
