Red hair reduces pain: due to genetic weirdness, people with ginger hair have reduced sensitivity



Studies have found that red hair has a higher PAIN threshold than blonde or black hair, because the skin’s pigment-producing cells lack the function of certain receptors

  • Red hair has defective receptors on the skin’s pigment cells, preventing it from tanning
  • It also has a hormone knockout effect, which leads to an increase in pain threshold
  • The end result is that ginger produces more opioid signals and a higher pain threshold compared to people with other hair color and skin tone










Ginger people can tolerate more pain than brunettes and blondes, and a new study has discovered why this is the case.

Studies have found that the skin cells that determine a person’s pigmentation are called melanocytes and are critical to determining a person’s pain threshold.

Red hair has genetic mutations, which means that the key receptors of its melanocytes are defective, so it cannot turn melanin into black.

The chain reaction of this effect is a chemical imbalance, leading to a series of different hormones, and ultimately enhancing the effect of opioid receptors that block pain.

The end result is that ginger produces more opioid signals than other people with different hair color and skin tone, so the pain threshold is increased.

Researchers at Massachusetts General Hospital observed red-skinned mice in the laboratory.

The skin cells of rodents are similar to those of humans, and the causes of red hair are similar in the two species.

Dr. David Fischer led a previous study that found that due to the loss of melanocyte function, hot hair cannot produce dark pigments and tan.

Ginger is the rarest hair dye in humans. Just like everyone else, there is a receptor on melanocytes called melanocortin 1, which protrudes from the cell surface.

Like humans, ginger is the rarest hair dye for humans. Just like everyone, there is a receptor on melanocytes called melanocortin 1, which mediates the production of dark skin pigments. But from a redhead's point of view, this is flawed. This causes hormone levels to be different from other gay people and leads to higher pain thresholds (primitive species)

Graying “is caused by stress”

Scientists have finally proved what traditional knowledge has taught us for decades-excessive pressure can make hair gray.

However, researchers at Columbia University have also found that hair that has only recently turned gray can reverse this process.

Scientists say that reducing stress can prevent gray hair and hope that drugs can be developed that can further prevent harmful processes.

Studies have found that the hair around the scalp can reverse gray hair. It also found that beard and pubic hair can regain their color when they start to turn gray.

Scientists believe that the root of the blushing problem comes from changes in metabolic pathways, which form proteins in the human body.

These pathways are severely affected by the hormones that a person produces when under stress, so relieving stress can eliminate this process.

Its normal function is to control when the body begins to produce dark brown or black pigments.

However, it does not work in red hair, causing many ginger skins to be pale, never turn bronze, and easily sunburned.

But Dr. Fisher discovered that these defective receptors also altered the production of a chemical called POMC, which then degrades into various hormones.

These hormones create a balance between pain suppression and pain enhancement receptors.

In red hair, damaged melanocortin 1 receptors result in less POMC production, so their derived hormone levels are lower.

This means that the equilibrium concentration in red hair is lower than in people with other hair colors.

Therefore, this enhances the effects of other hormones (not those produced by skin pigment cells), thereby enhancing the effects of opioid receptors that relieve pain.

Therefore, the researchers concluded in a study published in Science Advances that the pain threshold of red hair is elevated.

Dr. Fisher said: “These findings describe the early evidence that underpins the mechanism of pain thresholds under different pigmentation backgrounds.”

“Understanding this mechanism can validate these early evidence and provide medical staff with valuable recognition when caring for patients with different pain sensitivities.”
