Environmental Insights

🏢

Indoors & Windows

Standard glass blocks over 95% of UVB rays, the primary cause of sunburn. Your exposure indoors, even in a sunny room, is significantly lower than outside.

☁️

Cloud Cover

Thick, heavy clouds can block most UV radiation. However, thin or broken clouds can scatter UV rays, sometimes increasing your total exposure compared to a clear day.

🏞️

Reflection & Altitude

Surfaces like snow, water, and sand can reflect UV rays, increasing your exposure. UV intensity also increases by about 10-12% for every 1000 meters in altitude.

Monitoring Tools
