New Delhi, Oct 20: Many people have grown up viewing the sun as a threat to their health, associating exposure to its rays with premature wrinkles, sunspots and skin cancer. The belief has prompted many to adopt protective measures such as sunglasses, wide-brimmed hats, parasols and sun sleeves to minimise exposure to sunlight.
However, journalist Rowan Jacobsen, in his latest book *In Defense of Sunlight* (2026), argues that the widespread aversion to sunlight may have gone too far. He highlights decades of research linking moderate outdoor sunlight exposure with several positive health outcomes.

One particularly striking study, which followed nearly 30,000 Swedish women over 20 years, suggested that avoiding sunlight could be a risk factor for death comparable to smoking.
Sunlight is believed to support physical health in several ways, including by stimulating the production of vitamin D and encouraging the release of compounds such as nitric oxide, which can help lower blood pressure.
Sunlight may also offer mental health benefits. Exposure to sunlight on the skin helps the body release endorphins, which act as natural opioids, and may help protect against depression. Furthermore, appropriate exposure to sunlight during the day and darkness at night helps regulate the body's circadian rhythm, improving sleep quality and overall well-being.
However, experts continue to emphasise the importance of moderation. Excessive exposure to sunlight and ultraviolet (UV) radiation can be harmful, making sun protection, including the use of sunscreen, essential.
Jacobsen's work highlights how excessive fear of sunlight could potentially undermine rather than protect health. The key, therefore, is to strike a balance between obtaining the benefits of sunlight and avoiding overexposure.
One approach is to listen to the body's signals and seek shade when feeling overheated or overstimulated. While maintaining moderation requires awareness and adjustment, Jacobsen's central message remains simple: “Get sun. Not too much. Go outside.”
