How does sunlight actually help us?
Vitamin D plays a lot of crucial immune functions in our body. We need it for tissue integrity, production of antimicrobials (to defend you from virus, bacteria etc.), to regulating immune responses, providing appropriate tolerance and preventing excessive inflammation.
Having adequate amount of vitamin D promotes a robust population of T-regulatory cells (T-reg), and interleukin-10 expression. This creates an environment where our immune system is ready to learn tolerance. And anything you put on top (such as immune modulation) will be more effective.
If you live above 37 degrees latitude in the northern hemisphere, or below 37 degrees in the southern hemisphere, your skin makes very little vitamin D except during summer months.
Vitamin D supplementation becomes very helpful although it’s worth noting that supplementation does not replace the vitamin D we can make from sunlight, and the quality of supplements really matter.
To date, I still have not found a supplement that ticks all the boxes for me, I just have to choose what’s ‘OK’.
The widespread use of sunscreens have also resulted in a lot of chemicals from those sunscreens in the air. Which means that people are not necessarily making optimal levels of vitamin D just because they are in the ‘right’ part of the world.
People who live in the tropics have also been found to be vitamin D deficient because people spend a majority of time indoors in today’s lifestyle.
