Question

Body temp - 38 deg cel

AC room temp - 18 deg cel

diffrence - 20 deg cel

During summers in above circumstances you wear just a shirt but in winters why do you wear jacket in the room though the diffrence of temp is same?

Answer 1

if its so easy just answer it your self

Answer 2

Well, I often end up wearing a jacket in the office in the summer because I am acclimatized to the warm weather and the darn AC is so comparatively cold.  But maybe that's just me.

Here are some ideas:  Surely the humidity is different.  On a cold winter day, warming up all that cold air brings the relative humidity way down inside (that's why we get dry noses and static in the winter).  That low humidity makes our bodies cool off quicker, so the same temperature "feels" cooler.  

Another effect may be infrared heat.  Even though the air temp in the winter may be the same, you may have very little infrared heat coming in through the windows--you may actually be radiating your body heat out the windows or toward cold walls.  In the summer the opposite: hot walls or windows radiate a lot towards us, making it seem warmer even though the air temp is the same.  

Heat transfer occurs through evaporation (phase change), conduction, convection, and radiation, so you have to consider all of these in a possible answer to that question.
