Human biology has evolved mechanisms to handle solar energy, with melanin playing a role in managing sun exposure.

“our biology has all these mechanisms to handle higher energy wavelengths like we just talked about so yeah you can overdo it especially if you're in a high UV environment like Costa Rica like you need to be careful and build up a solar callus but that's why we have melanin and that's you know something that's really important at a biological level and has some really cool rabbit holes and how it's you know handling energy from from the solar Spectrum but it's energy right this is energy for our biology”
