It could be that they are just very rare (which can make them a sought-after prize), it could be that red hair just grabs your attention and serves as an advantage, or it could be that red is an indicator of youth and fertility. The MC!R gene that can cause red hair codes for a receptor that is related to a family of receptors involved in perceiving pain, which may explain why mutations in MC1R would increase pain perception. This could be a valuable finding for medical personnel caring for patients. Why is Stairway to Heaven the Forbidden Riff? https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1362956/ However, I've never seen anything beyond anecdotes regarding alcohol sensitivities.

This is not tolerance, but resistance . if you are walking down the street, there is nothing that you can see in somebody that will tell you how much anesthesia they need, except red hair, says Daniel Sessler, who studied redheads resistance to anesthesia, finding that found that redheads require19 percent more inhaled, general anesthesia than their dark-haired counterparts. This could explain the redhead vs. non-redhead difference in pain tolerance. But because their bodies dont produce melanin, which can help protect the skin against damaging ultraviolet rays, it also means that gingers are at greater risk for developing melanoma. MC1R is a receptor for the pain-relieving hormones, proopiomelanocortin (POMC) and beta-endorphin. These neuroadaptations compensate for the physical, mental, and behavioral effects of alcohol. Redheads are innately resistant to pain medication, which means that they need more right from the start to have any effect, without ever having had any before. The pigment found in redhair that makes it red is called pheomelanin. In contrast, researchers in another 2005 study found that people with MC1R mutations have a higherpain sensitivity.

The MC1R gene determines how much melanin is produced. The value of the Name: field is not valid. Yea it hurt but seriously a papercut on my amputated finger is excruciating and having kids, meh. But, in redheads, the mutation to MC1R leads to the production of a red pheomelanin, the pigment that gives the specific hair color. Many other websites picked up a similar story, quoting a study published in a magazine by the Oxford Hair Foundation.

Research has shown that redheads have a greater tolerance for alcohol and are more sensitive to pain than people with other hair colors. Do redheads have a higher tolerance for alcohol? The same mechanism that causes this red-tinged pigment also stimulates some hormones, including those called endorphins. However, theres no scientific consensus about redheads enhanced pain threshold. However, they found that the pain tolerance was increased when the mice carried a MC1R variant.
