Safe Sun Exposure Promotes Longevity

Does sunlight help or harm longevity?

Both. Moderate sun exposure improves vitamin D and cardiovascular health, but excess exposure raises cancer risk.

Explanation

Sunlight stimulates vitamin D synthesis, critical for bone, immune, and cardiovascular health. Low vitamin D levels are linked with higher risks of mortality and chronic disease. Outdoor sun exposure also synchronizes circadian rhythms, improving sleep and metabolic regulation.

However, excessive UV exposure damages DNA and raises risk of skin cancers, particularly melanoma. Balancing safe exposure with protection against overexposure is essential for long-term health.

Practical Emphasis: Aim for 10–20 minutes of midday sun on exposed skin most days, depending on skin type and location. Use sunscreen for prolonged exposure.

Takeaway (Action Tip)

Practice moderate sun exposure for vitamin D while protecting against skin damage.
