The best time to be in the sun depends on your goals. Are you aiming for optimal vitamin D absorption, minimizing skin cancer risk, or capturing the perfect photograph?
For Vitamin D and Minimizing Skin Cancer Risk:
According to several studies, including one published in PubMed (https://pubmed.ncbi.nlm.nih.gov/18348449/), midday (around noon) is ideal for maximizing vitamin D production while minimizing the risk of cutaneous malignant melanoma (CMM). At noon, the sun's UVB rays, crucial for vitamin D synthesis, are most intense. However, always remember to practice sun safety with sunscreen and limit exposure duration. Other sources (https://www.healthline.com/nutrition/vitamin-d-from-sun) confirm midday, especially in summer, as the optimal time.
For Photography:
Photographers often cite the "golden hour," the hour after sunrise and the hour before sunset, as the best time for outdoor photography (https://bellawangphotography.com/best-time-to-do-photos/, https://candaceweir.com/besttimeofdayforphotos/, https://www.samanthashannonphotography.com/what-is-the-best-time-of-day-for-outdoor-photos/). During this time, the light is softer, warmer, and casts longer shadows, creating a more aesthetically pleasing and flattering effect. However, this is less about the sun itself and more about the quality of light it produces at these times. Avoid direct overhead sun, as this can create harsh shadows and "raccoon eyes" (https://www.ldavidlikesphotography.com/blog/best-time-of-day-for-outside-pictures).
Considerations:
- Latitude: The intensity and angle of the sun vary with latitude and season. The optimal time might shift slightly depending on your location.
- UV Index: Always check the UV index forecast before sun exposure. Higher UV index means a greater risk of sunburn and skin damage.
- Personal Sensitivity: Individual skin sensitivity varies. Some people burn more easily than others.
