The second law of thermodynamics states that in any energy exchange, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state, which is often interpreted as the increase of entropy, or disorder, in the system. In this case, as you exert yourself, your body's processes are increasing entropy through the production of heat and sweat.
