1. What is the Sunbathing Calculator?

The Sunbathing Calculator estimates safe sun exposure time based on your skin type and current UV index. It helps prevent sunburn while allowing optimal vitamin D production.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Skin\ Type\ Factor \) — Your skin's resistance to UV radiation (in minutes)
• \( UV\ Index \) — Current ultraviolet radiation intensity

Explanation: The equation calculates how long you can stay in the sun before risking sunburn, based on UV intensity and your skin's sensitivity.

3. Importance of Safe Sun Exposure

Details: Proper sun exposure balances vitamin D production with skin cancer prevention. This calculator helps find your personal safe exposure time.

4. Using the Calculator

Tips: Enter your skin type factor (typically 5-30 minutes for most skin types) and current UV index (check weather reports). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my skin type factor?
A: Fair skin typically has 5-10 minutes, medium skin 15-20 minutes, and dark skin 25-30 minutes as a starting point.

Q2: Where can I find the current UV index?
A: Most weather apps and websites provide UV index information, or check your local weather service.

Q3: Should I reapply sunscreen during this time?
A: Yes, sunscreen should be reapplied every 2 hours regardless of this calculation, especially if swimming or sweating.

Q4: Does this account for altitude or reflection?
A: No, this is a basic calculation. At high altitudes or near water/snow, reduce exposure time by 30-50%.

Q5: Is this suitable for children?
A: Children's skin is more sensitive - use half the calculated time as a precaution.
