What colour are you?

What colour are you? If life was lived not in human-age terms but geological terms, you might have had a different answer each day. No, I am not crazy and will explain. The colour of your skin is largely a function of the amount of sunshine. How much are you getting? You may not realise it, but the amount varies. Depending on where you live. The amount of pollution. The cloud cover. Even the season. Planet Earth gets about 240 watts per square meter of solar power. However, this is widely distributed. The equators get the most. The poles get nothing in winter. Your skin colour adapted to this compensate for this difference.

It is believed that mankind migrated from Africa. As they made their way upward, the colour of their skin was compelled to adapt. To ensure the absorption of Vitamin D. The type of melanin in your skin helped you do this. Dark skinned have dominant eumelanin which acts as a natural sunscreen. Fair skinned people have more pheomelanin which increases the efficiency of absorption of Vitamin D. It had nothing to do with looks or intelligence.

The human body needs 2500 to 5000 units of Vitamin D each day. This can vary wildly depending on your current levels. If you source your Vitamin only from the sunshine and not food, everything comes into play. Location, weather, season, skin colour. Foolishly, we use sunscreen instead. If you did, you probably just affected your ability to absorb a critical Vitamin. One that caused mankind to adapt and evolve for. It was that critical.

The Sunshine is by far the best way to get Vitamin D. Ensure that where ever you live, your lifestyle adapts to ensure this. Unfortunately, your skin colour won’t change in this lifetime to guide you. You need to use your own intelligence. Science can help. See here.  I did mine. I need to be out in the sun for 24 hours to get the amount I need.

Note: people with fair skin can generate toxins that can lead to cancer due to long-term exposure to the sun.
