In humans, the MC1R is found in a variety of tissues, with a particularly high concentration in the skin. However, they found that the pain tolerance was increased when the mice carried a MC1R variant. Redheads have a higher tolerance for spicy foods. But this experiment used thermal pain (heat and cold) instead of electrical currents. Overall, theyre tougher than pretty much all other hair colors. While this may be due to the red hair, it has other implications. They may be less sensitive to electric shock, needle pricks and stinging pain on the skin.

They feel more pain but are also more resistant to some types of pain, they are resistant to some conditions and are more at risk from others. A number of studies have shown redheads feel pain differently and have different body reactions. In addition, MC1R has also been reported to be involved in cancer (independent of skin coloration), developmental processes, susceptibility to infections and pain, and even arthritis. As a result, after exposure to UV rays, PTEN is destroyed at a higher rate, and growth of pigment producing cells (called melanocytes) is accelerated as it is in cancer, the researchers said.

MC1R stands for melanocortin receptor and is a key regulator of intracellular signaling, with a plethora of potential applications. Anesthesia stages. The same MC1R mutation that turns their hair red also releases a hormone in the brain that has the ability to mimic endorphins.
