WHY SUN EXPOSURE?

• Sunlight is essential for Vitamin D, mood, sleep, and overall well-being, but overexposure puts your skin at risk. Sun Exposure helps you find the right balance — enough sun for health and glow, without crossing into damage.
• Track sun exposure with or without an Apple Watch. Automatic all-day sun tracking with Apple Watch requires watchOS 10 or later. Sun Sessions work on iPhone for on-demand tracking anytime.
• Privacy first - no personal data leaves your device unless you choose to share it.

Disclaimer: Consult your doctor to determine the right amount of sun exposure for you. Always use sunscreen, hats, and shade as needed.
