Answer:
"Cold" in this case, is defined as a difference between the body temperature and the room/ambient temperature.
If the body temperature is higher than the room temperature, then the "sensors" in our skin will sense that the ambient temperature is lower than ours, then we feel "cold"
The room temperature is: 36.1°C.
The higher body temperature is the one of Shyam, 36.4°C
The difference is really small:
36.4°C - 36.1°C = 0.3°C
But still, he will feel the room a little cold for him
