Therapy reduces body heat loss

The proposed mechanism asks whether a therapy for middle-aged skin could reduce body heat loss in sunlight by converting extra absorbed light into heat. Therapy components may absorb more solar energy, converting it to heat that flows into the body while sweat release and evaporation, sweat turning to vapour and carrying heat away, remain preserved. Researchers would independently vary radiation and formulation absorption while holding water-vapour permeability comparable. Direct calorimetry of the coating-skin system, a heat-exchange measurement, would test whether extra absorbed energy each second matches a radiation-dependent heat-loss deficit. A match would support a photothermal contribution. Much less absorbed energy would weaken it as the main explanation.
