4. Our ability to handle Ultraviolet Radiation
Ultraviolet Radiation is unlike all the other types of radiation we deal with on a regular basis. We actually do run into radiation on a regular basis via things like CT Scans, MRIs, and even X-Rays. All are low forms of it but still exist. Meanwhile, the biggest radiation we deal with is, well, the sun. UV Radiation comes right from that big ball of fire that heats the Earth.
The way we handle UV radiation with Melanin. For those unaware, Melanin handles things like the darkness of our skin, hair, and even the iris of our eyes. Melanin is a natural fighter of the sun, allowing things to get darker and lighter to fight off the sun’s rays. In fact, Melanin is the reason people tan when they go outside during the summer. Melanin naturally absorbs the sun’s impact, protecting the cells from damage. It does not do everything, so sunscreen is a must!
