How To Take Sun And Handle Exposure To Sun?
What are optimal procedures for handling intentional and non-intentional sun radiation?
Essentially: What factor/protection to use in different circumstances?
For me the main positive points are:
- Building protection*
- Misc health benefits
- Long term skin damage (aging)
- Negative effects from creams etc.
â€‹(Personally I do not have much acute problems, except for local sunburn)
Intuitively for me, the positive effects should be logarithmic with intensity (less than proportional), and negative effects should be more like proportional (Then low exposure over long time should be optimal). But from I see written about this, it seems to be more about dayly dose than intensity, and that both effects are proportional with a daily ceiling - Talk like "With factor x you can stay x times longer in the sun", talk about Minimum Effective dose, maximum limit per day (But that is perhaps more for short term problems?)
How does this change if you take supplements to limit damage from the sun?
(Are the positive effects also decreased?)
Also, how should you adjust net exposure from day to day?
(*)In my case, I only have exposure in short periods every year. There will be periods without any protection from sunscreen, so for me it makes sense to build natural protection, for example by using a low factor cream. Also high factor creams must have some negative tradeoffs with regards to durability and negative affects from the cream itself. Both these points make less sense if daily dose is more important than intensity.
