Nice article, but it seems to me that what you're referring to as "sensor adaptation", at least in the context of the water experiment, might just as well be explained by the localized temperature change in the body tissue. Due to the change in body tissue temperature, the sensors detect less of a difference between their surrounding tissue and the water. Simply think of the temperature sensors as not being a measure of absolute temperature, but rather an indicator of relative temperature difference.
Oh I get it
When i did this experiment i realized that mine hands changed. my left hand was in the cold water and right hand was in the hot. When i put both hands in the warm temperature, the temperature of my hand changed from hot to cold and cold to hot. can someone please explain?.
