I always assumed that this was somewhat natural, but it may just be my upbringing. I grew up in a warm country without air conditioning, so open windows were the only way. Then moved to a cold country and noticed the sensation. I put 1-1 together.
In my case my face, specifically my forehead, feels warm. Not to the touch, but more to the nerves. I think it may be different for different people.
