In fact, about a decade ago, British researchers reviewed all the existing medical literature on the subject and found no evidence to substantiate increased bleeding in red-heads.
Red-haired individuals are known for their reputation of increased bleeding during surgical procedures and in women after childbirth [1].
The MC1R gene might actually make redheads look young
According to research published in Current Biology, people with the MC1R gene, aka the gene that produces red hair and fair skin, tend to look several years younger than their non-ginger counterparts.
About 1–2% of people of European origin have red hair. Especially female redheads are known to suffer higher pain sensitivity and higher incidence of some disorders, including skin cancer, Parkinson's disease and endometriosis.
In summary, redheads are more sensitive to thermal pain than women with dark hair but do not show differences in baseline electrical pain thresholds. Furthermore, redheads are more resistant to the analgesic effects of subcutaneous lidocaine.
Yes, according to science, people with ginger hair are better in bed. This is because of a specific gene connected to redheads - the MC1R gene. This gene makes the individual more sensitive to touch than people with other hair colours.
Research has shown that people with red hair perceive pain differently than others. They may be more sensitive to certain types of pain and can require higher doses of some pain-killing medications. However, studies suggest that their general pain tolerance may be higher.
Lifespan: up to 20 years in captivity, 5-10 years in the wild.
This is to be expected because red hair is associated with fair skin, which is more vulnerable to UV radiation [1]. Less expectedly, red hair is also associated with pain sensitivity, endometriosis, Parkinson's disease, decreased platelet function and, perhaps, defects in the immune system [2–11].
Redheads actually have less hair than most other people. On average they only have 90,000 strands of hair while blonds, for example, have 140,000. However, red hair is typically thicker so it still looks just as full.
A new survey reported by the Daily Mail says ladies should start worrying in their 30s: specifically, ages 30, 32, and 35 (for redheads, brunettes, and blonds, respectively).
The results showed the average IQ of blonde-haired women was 103.2, 102.7 for brown hair, 101.2 for red hair and 100.5 for black hair. However, the differences were so small as to be unlikely to represent a real difference.
Simply put, achromotrichia is the absence of pigment in the hair. But while non-redheads gradually go grey and then perhaps to fully white hair, redheads actually retain their ginger colour for a lot longer, skipping out the greying stage.
REDHEADS are significantly less likely to age badly.
According to their findings, those who carry a variation of the MC1R gene responsible for red hair, look around two years younger than they actually are.
Redheads (men and women) differ chemically from the rest of us in that they can't make melanin (the brown pigment in freckles and tans). Instead, they make pheomelanin, which is reddish. Their sweat doesn't differ in composition from anyone else's, so there is no reason for them to smell different.
Redheads tend to have pale, pink nipples. The reason is simple and goes back to the reason they are redheads. The balance of melanin they were dealt in their genetic makeup impacts more than their skin pigmentation. There are two types of melanin: pheomelanin and eumemelanin.
Ginger has been used in alternative medicine as a possibly effective aid in treating nausea and vomiting after surgery, dizziness, menstrual pain, arthritis, preventing morning sickness. Ginger has also been used for weight loss and to prevent motion sickness and seasickness.
Boost brain function: There are a lot of anti-inflammatory properties of ginger that can help your brain. For example, ginger increases serotonin and dopamine levels. This can reduce inflammation, which may cause depression.
Yes, ginger can help you lose weight. Experts note that the research shows, “… some convincing evidence to support the efficacy of ginger in obesity management.” Ginger affects how your body burns fat (thermogenesis), digests carbohydrates and uses insulin.
Ireland has the highest number of red-haired people per capita in the world with the percentage of those with red hair at around 10%. Great Britain also has a high percentage of people with red hair.
In the array of possible natural hair colors, dark hues are the most common — more than 90 percent of people worldwide have brown or black hair. That's followed by blonde hair. Red hair, occurring in just 1 to 2 percent of the population, is the least common.
Most (natural) redheads will have brown eyes, followed by hazel or green shades.
The skin of a redhead is thinner compared to others and is derived from the ectoderm. Teeth enamel is also derived from the ectoderm and thus is thinner than usual. Since the enamel coating is thin, the inner layer of tooth-dentin is more visible and offers a yellowish appearance.
Previous studies had shown that redheads inherit two versions of the MC1R gene that leads to red hair – one from their mum and one from their dad. Although almost everyone with red hair has two copies of the red-haired version of MC1R, not everyone carrying two red-haired versions is a redhead.
Here's what studies have revealed about redheads and pain: They need about 20 percent more anesthesia to be sedated. They also need more local topical anesthetics, such as lidocaine or Novocain, which is why many redheads have a fear of dentists, according to the American Dentistry Association.
