In winter we use blanket, why? how will blanket help us to feel warm?
Answers
Answer:
Your body generates heat. Every hour of every day, just by the process of living, your body is generating heat. We're all constantly losing heat to the environment. If you're generating heat faster than you can lose it (like when you're doing heavy exercise and/or you're in hot weather) then you heat up. If you lose heat faster than your body can produce it (like in cold weather) then you get cold.
What blankets (and coats, and sleeping bags) do is slow down heat transfer, which prevents your body heat from being lost to the air around you. That allows your own body heat to keep you warm.
Cold air tries to carry your body heat away. Blankets form a barrier between your body and that cold air. Since heat doesn't tranfer through the blankets very well, they keep the heat from getting out. The colder the surroundings are, the more insulation you need to keep your body heat from escaping too fast. As long as you're bundled up well enough, your own body heat can keep you warm even in very cold situations.
Now, this only works because you're generating heat. If you were to put a blanket around something that generates heat (say, a car engine, or a light bulb), those things would heat up, even in cold weather. In fact, they could heat up enough to be dangerous, so don't try that. But if you wrap a blanket around something that doesn't generate any heat (like a piano), it won't do much good. The blanket doesn't create any heat, it just keeps the heat you're already creating inside.

Answer:
Blanket helps us to maintain our body temperature,it does not allow the heat to exit from ,and also does not allow the outer cold ness to come inside the blanket.
