This assessment provides statistical probability and mathematical interpretation based on validated clinical equations. It is not a diagnostic tool.
Calculates the maximum safe time for sun exposure before skin damage (erythema) occurs, based on the current UV Index and your Fitzpatrick Skin Type. This tool helps prevent sunburn while also identifying the window needed for optimal Vitamin D synthesis.
The UV Index was first developed by Canadian scientists in 1992 and standardized by the WHO in 1994 to provide a simple, universal language for sun safety.
If you are at a high altitude or near water, reduce the recommended time by 20%. Reflection from sand or water increases UV intensity significantly.
