+    ### 📚 UV Index Reference Guide
+    
+    | UV Index | Risk Level | Time to Burn* | Action Required |
+    |----------|------------|---------------|----------------|
+    | 0-2 | 🟢 Low | 60+ min | Basic protection |
+    | 3-5 | 🟡 Moderate | 30-45 min | SPF 30+, seek shade |
+    | 6-7 | 🟠 High | 15-20 min | SPF 30+, protective clothing |
+    | 8-10 | 🔴 Very High | 10-15 min | SPF 50+, minimize exposure |
+    | 11+ | 🟣 Extreme | <10 min | SPF 50+, avoid sun 10am-4pm |
+    
+    *For fair skin types. Darker skin types have longer burn times but still need protection.
+    
+    **💡 Pro Tips:**
+    - Apply sunscreen 15 minutes before sun exposure
+    - Use 1 ounce (shot glass amount) for full body coverage  
+    - Reapply immediately after swimming, sweating, or towel drying
+    - UV rays penetrate clouds - protect even on overcast days
+    - Water, sand, and snow reflect UV rays, increasing exposure
