Those with red hair have a mutation in the melanocortin 1 receptor (MC1R), which is responsible for skin pigmentation and pain perception. Treadmill vs. At any rate, redheads exhibit a number of intriguing biological features. As a result, redheads can take smaller doses of these drugs to reach the same level of pain tolerance as others. But things get even more interesting.

Direct alcohol tolerance is largely dependent on body size. MC1R is responsible for ginger-haired differences and is inherited by redheads. Current estimates put that number between one and two percent of the global population. This gene may help scientists develop better anesthetics and pain-relieving drugs. The mutation suppresses function of the melanocortin 1 receptor. If youre concerned about your tolerance for alcohol, its a good idea to take regular breaks now and then. Annals of Neurology. In fact, scientists have known for 15 years that mice and humans with the mutated MC1R gene feel pain differently than others.

Research has found that redheads have enhanced tolerance to hot and cold pain. Genetic studies have shown that a protein-coupled receptor called MC1R holds the key to this mutation.
