I do not think that we need to protect our body from nature, instead we should live with it. But yes, it is not possible every time, the changing weather conditions does not allow us to be the same every now and then. Hence, we have to go accordingly. When its extremely hot, we have no other choice than to sit in AC or cooler because obviously the heat is too much and we need some amount of comfort as well. But if the season is rainy, we should enjoy it :) Because elders say that the rain drops helps to heal any pimples or acne that we get during summers. Similarly winter has its own significance. There is no need to protect our body much from weather , because what has to happen will happen inspite of the utmost care.
Stay happy and stay healthy .
A positive attitude will lead to positive results.
