Loading ...People with red hair feel more pain than people with blond or dark hair. It is scientificaly proven that people with red hair need about 20% more anaesthetic during operations than other patients.
The cells that produce skin and hair pigment have a dysfunctional melanocortin 1 receptor in people with red hair.
This dysfunction triggers the release of more of the hormone that stimulates these cells, but this hormone also stimulates a brain receptor related to pain sensitivity.
This causes people with red hair to be more sensetive to pain.
Poor redheads!
