Winters in most places have very low humidity. For that, the moisture of our body is lost easily and skin becomes dry quickly.
Why is echo not heard in our living rooms? To hear echo, the minimum distance between the source and the reflector must be 17m. When this distance is more than 17m, the reflected sound can be distinguished from the original. As the length of our rooms is less than 17m, we don't hear echo.
