• Your body produces heat.
• Generation and removal of heat must be balanced to keep the body temperature equal.
• Heat transfer is enabed by conduction, convection and radiation.
• If the body temperature equals outside temperature, convection and radiative cooling is reduced
• your body temperature rises till equilibrium is achieved

All valid points. But regarding the measurements, neither LTT or GN testing methodology are realy scientific. Those are youtubers with limited understanding of experimental design and analysis. I have never seen them do simple significance tests or try to explain the variability in the data. But I havent watched all the videos so 乁⁠(⁠ ⁠•⁠_⁠•⁠ ⁠)⁠ㄏ
