Introduction: Why the UV Basics Matter
The UV index gives a simple 0–11+ read on sun intensity. Values from 3 upward call for protection. With SunCare, you get live UV, contextual guidance, and smart timers so you can enjoy the sun safely—without guesswork.
Read UV at a Glance
- 0–2 Low – sunglasses optional; protection by preference.
- 3–5 Moderate – SPF recommended; find shade at midday.
- 6–7 High – SPF, hat, sunglasses; take shade breaks.
- 8–10 Very High – seek shade; reapply diligently.
- 11+ Extreme – minimize exposure; cover up.
Smarter SPF Timing
Your reapply window depends on SPF strength, current UV, activity (sweat, swim, towel), and how much skin is exposed. SunCare adapts reminders to your context so you top up before protection lapses.
FAQs
What happens at UV 3 and above?
UV 3+ is the threshold where unprotected skin can begin to burn. Use SPF, shade, and sunglasses—SunCare highlights this level so you know when to act.
How long does protection last?
It varies with SPF, UV, and activity. A common baseline is about two hours at moderate UV with SPF 30, but heavy activity shortens that window. SunCare’s timer adapts as conditions change.
Is higher SPF always better?
Higher SPF blocks a bit more UV but no sunscreen is permanent. Consistent reapplication and coverage are what keep you protected.
