They should always tell their surgeon, anesthesiologist and dentist that they will most likely need more anesthetic or local anesthetic, and that they might be more sensitive to opioids, she says. In addition, mutations in the MC1R gene can increase redheads tolerance to alcohol. This gene may help scientists develop better anesthetics and pain-relieving drugs. If the patient is indeed a natural redhead, she carefully monitors the patients reaction while administering anesthesia to ensure they are properly anesthetized. All rights reserved.

But future research may be able to answer questions about how anesthesia affects the brain and higher functions. Source: Barry JD. Because the study was conducted on mice and cells in a lab dish, more research is needed to see if the same mechanism occurs in people. The same mutation that makes their hair red is also what causes them to be more sensitive to temperature changes even slight ones.

They found that redheads are more sensitive to thermal pain and are less sensitive to electric shock pain. A team at the University of Louisville discovered in 2005 that redheads are 'significantly' more sensitive when it comes to tolerating cold and heat pain, and they are also able to perceive cold. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1362956/ However, I've never seen anything beyond anecdotes regarding alcohol sensitivities. 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.
