our body temp is 36.6Centigrade, if room temp is 35 then also we feel hot why. instead of cooling effect?

Answer 1

Respiration produces energy. That energy continuously sinks to the surrounding environment. To maintain a constant temperature a healthy body would need a surrounding temperature of 20 to 25 degrees.

Any temperature higher than that would reduce the amount of heat removal (a function of the delta-T). Any temperature less than that would increase the amount of heat lost to the environment.

Of course metabolism (e.i. the amount of heat produced by respiration), circulation, and body fat (an excellent bio-insulator) would change the effect, thus the reason that obese people commonly sweat when others do not.

Answer 2

Our body is constantly heated from the inside so we need to loose that heat. And 35 centigrade is just too high to loose it quickly enough except if we sweat much because that helps cooling.

Answer 3

Our internal temperature is higher. We need to lose heat to the outside environment to help us cool down. At 35C outside, we do not lose heat fast enough, so we feel it is hot.

On the other hand, we are used to temperature that is cooler than 35C, so compare to what we use to, we know it is hot.
