MC1R, or melanocortin 1 receptor, is a protein that is involved in melanogenesis. Intraoperative awareness risk, anesthetic sensitivity, and anesthetic management for patients with natural red hair: A matched cohort study. The same MC1R mutation that turns their hair red also releases a hormone in the brain that has the ability to mimic endorphins. Understanding this mechanism provides validation of this earlier evidence and a valuable recognition for medical personnel when caring for patients whose pain sensitivities may vary.. The same mechanism that causes this red-tinged pigment also stimulates some hormones, including those called endorphins. (n.d.).

Its used as a local anesthetic to prevent pain during procedures. According to observations, redheads have a higher basal threshold of pain tolerance, or nociception, than others, and are more sensitive to opioid analgesics. At any rate, redheads exhibit a number of intriguing biological features. The existence of racial differences in alcohol sensitivity between Oriental and Caucasian populations has been well documented. But when it does finally come its excruciating. The MC1R gene also plays a vital role in pain perception. This suggested that two MC1R variants are linked to lower pain sensitivity. (Later, science proved that skin mantle a thin, acidic film on our skins surface is actually more acidic in redheads, causing perfume to more quickly evaporate when applied and potentially emitting a unique smell of its own.). Finally, a 2020 study suggests that the MC1R variants related to pain sensitivity might actually be different than the variants that cause red hair. Is it Safe to Eat a Turkey Frozen For 2-3 Years?

Research has shown that redheads have a greater tolerance for alcohol and are more sensitive to pain than people with other hair colors. For instance, one study found that people with red hair are more sensitive to thermal pain, while another showed that they are less sensitive to a wide array of painful stimuli, including electrically induced pain. This is particularly important because it means researchers can carry out studies on it on other animals, and although the findings may not carry out the same way on humans, these studies can still yield valuable clues.
