The human body loses heat in a number of ways including conduction and convection. Conduction is heat transferred between two areas of matter and convection occurs within fluids and gases like air. These two combine when we lose our heat to the air around us. The faster the air is moving the faster it takes our heat away from us. This results in your skin feeling colder than it would in the still air as the heat is rapidly drawn from your body. This is known as the wind chill factor and it will always be colder than the still air temperature.
