Red Hair people always seem very attractive simply because they are rare to find. Only single digit population in this world has red hair. Not a surprise that their genes are responsible for this.
Why are people redheads?
MC1R, a gene is responsible for this mutation, which ciphers melanocortin-1 receptor. A pigment called melanin produces two forms which are eumelanin and pheomelanin. These two forms decide the color of a person’s hair and skin.
- Eumelanin people tend to have more of brown or black hair and dark skin which tans easily.
- Pheomelanin tend to have red or blond hair with a light-colored skin which tans poorly.
People with pheomelanin have an increased risk of skin damage caused by sun exposure since it doesn’t protect skin from Ultraviolet radiations.
Ultravoilet radiations are not the only danger that readheads face. Rather they are also prone to dangerous disease like cancer.
How can MC1R cause cancer?
Everyone in this world has mutated tumor cells but people with MC1R gene are loaded with mutated tumor cells and all mutations are not caused by Sun’s radiations.
The number which is associated with the MC1R mutation is equivalent to additional 21 years of sun exposure as compared to people having eumelanin.
These Mutations prevent collaboration of MC1R and PTEN which helps to stop any kind of cancer. When UV rays heats up our skin in sunlight, the PTEN is destroyed and it results in greater chances of cancer.
MC1R affects the brain which may affect the activity of endorphins – one of the body’s natural painkillers.
Prevention from skin Cancer
It is also important to understand that it isn’t just people with red hair who need to protect themselves from too much sun. Everyone should take care of the skin and should only come out in the sun with proper safeguards. Apply sunscreen with SPF30 or more while going in heavy sun exposure.
Cover up yourself with clothing and UV blocking sunglasses while going out helps a lot.
