This is especially important when redheads have surgery. Dr. Edwin Liem studied the effects of inhaled anesthesia on women aged 19 to 40. He watched for unconscious arm or leg movements in response to electric shocks and found that women with red hair needed more of the drug to stop these reflex movements compared to those with dark or blond hair. “In a nutshell, redheads are likely to experience more pain from a given stimulus and therefore require more anesthesia to alleviate that pain,” he says.
