As a biologist with a focus on human genetics and physiology, I can provide some insights into the question of whether redheads feel the cold more than people with other hair colors.
Red hair is a trait determined by a variant in the MC1R gene, which is associated with the production of a specific type of melanin called pheomelanin. This type of melanin is less effective at blocking harmful ultraviolet (UV) radiation from the sun, which is why redheads often have fair skin that is more susceptible to sunburn. However, the ability to feel cold is not directly related to the type of melanin produced by the body.
The sensation of cold is primarily a function of the body's thermoregulation system, which involves the skin, blood vessels, and the nervous system. When the body is exposed to cold temperatures, blood vessels near the skin's surface constrict to reduce heat loss. The nervous system also sends signals to generate heat through muscle activity, such as shivering. These processes are not influenced by the type of melanin present in the skin.
There is no scientific evidence to suggest that redheads have a different thermoregulation system that would make them more sensitive to cold. However, it is true that people with lighter skin may have less melanin overall, which can result in less natural protection from the sun's rays. This can lead to a higher risk of sunburn and potentially increase the risk of skin cancer, but it does not affect the perception of cold.
In conclusion, the color of a person's hair or skin does not determine their sensitivity to cold. The sensation of cold is a complex physiological process that is not influenced by the MC1R gene or the type of melanin produced.

Researchers think that the ginger gene, known as MC1R, may cause the temperature-detecting gene to become over-activated, making redheads more sensitive to the cold. ... That redheads are subject to sunburn and skin cancer must be linked to the difference in pain sensitivity."
