Annals of Neurology. 1 What this means behaviorally is that you act as though you are not intoxicated, maybe even at high levels of blood alcohol concentrations (BACs). All rights reserved. These hormones affect the balance between opioid receptors, which block pain. It is the same with pain medicine - the more you use it, the more you develop a tolerance to it, so the more pain medicine you need. While it makes redheads more susceptible to sunburn, that very sensitivity to ultraviolet rays also allows their bodies to produce more vitamin D, which is essential to bone development and good health. Theres another important difference, which we have saved for fun. MC1R is a receptor for the pain-relieving hormones, proopiomelanocortin (POMC) and beta-endorphin.

They found that the melanocytes in red-haired mice secreted lower levels of a protein called proopiomelanocortin (POMC). Well, ethanol is an established anaesthetic and alcohol more generally is considered to be an anaesthetic of sorts, so I suppose would make sense if alcohol was included in that innate resistance. This ultimately affects how the body receives pain signals from the brain, causing a heightened sensitivity to prescription opioid painkillers. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1362956/ However, I've never seen anything beyond anecdotes regarding alcohol sensitivities.

Theres another interesting bit about redheads: they produce their own vitamin D, in much higher quantities than the rest of the population. A study in mice revealed the mechanisms that may link red hair with greater pain tolerance. One volunteer carried an R151C mutation on one allele, while the other five were all carriers of the consensus allele. 1. 2007-2021 ZME Science - Not exactly rocket science. They found that mice carrying the MC1R red-hair variant had a higher pain threshold even without pigment synthesis. Blog Post Name must have at least 0 and no more than 256 characters. The mutation prevents MC1R from properly binding to a gene called PTEN, which helps protect against cellular changes that promote cancer. However, the mechanism underlying these findings remained . While blue is not common, green is the rarest color. Those with red hair have a mutation in the melanocortin 1 receptor (MC1R), which is responsible for skin pigmentation and pain perception. We all have this gene; however, sometimes the gene mutates, causing the characteristic reddish hue thats found atop gingers heads, along with pale skin and light eyes. Because of this trait, those with red hair tend to respond better to alcohol and opioid pain medications. REDHEADS are significantly less likely to age badly. They found that redheads are more sensitive to thermal pain and are less sensitive to electric shock pain.

According to observations, redheads have a higher basal threshold of pain tolerance, or nociception, than others, and are more sensitive to opioid analgesics.
