Are we more sensitive to temperature on either side of our body?

Question

I noticed I seemed to be colder on my right side than my left for no apparent reason like a cold draft or something.

Answer 1

Our cold sensory bodies, called bodies of Krause,  are concentrated on the upper arms and heat sensors, called Ruffinian bodies,  on our higher backs (in the area of the upper scapula). It is quite possible that your right or left side can have more of these sensory bodies.

Answer 2

I don't know. I suppose it's possible that a person's circulation could be more efficient on one side of the body than the other.

Years ago I got allergy shots. I noticed that when I got my shots on my left arm I felt more pain than when I got them on my right arm. My allergist told me that it's normal for a person to be more sensitive to pain on one side than the other. So perhaps that's also true with perception of temperature.

Still, next time you see your doctor you might want to mention this.

Answer 3

The sensitivity to temperature depends on how nerve endings are distributed to either side of our body. But having equal amounts of nerve ending would be normal.

We have more sensors for the cold than warmth.
