It's basically a way of sucking up to someone and it's almost as annoying and shallow as when girls post shit like omg stop being so perf! and then of course the required response is no that's you bb ð and it goes back and forth like that.
Temperature receptors. The sensory system involved in perceiving the changes in skin temperature begins with free nerve endings found in the dermal and epidermal layers of skin that can be functionally classified as cold and warm thermoreceptors.
Specialized sensory receptors called thermoreceptors are responsible for temperature sensitivity. These thermoreceptors are located in the dermis of the skin. A cold environment results to lesser blood flow near the surface of the skin. Thus, the body feels colder.
