Why does one start sweating at 25 degrees (Celsius)/77(F) even though the body temperature is much higher?
In:
Because the difference in temperature is much lower, and hotter temperature areas tend to have lower winds
When it’s really cold out, you lose a lot of heat, because heat likes to balance out and move to cold places. The bigger the difference between your body heat and the temperature outside, the faster the heat transfer.
When the heat outside is closer to your body temperature, that transfer of energy is much slower
You also have to consider wind. Wind blows air across the surface of your skin. As the air hits your skin, it heats up, thus drawing heat energy from your body. The higher the wind, the higher the number of particles bouncing off your skin, thus the quicker the heat loss. If you’re in a hot place, it tends to have less wind, so you can’t lose any body heat through this method.
