Sunlight exposure can have ‘massive’ health benefits, doctor says

As spring arrives and the weather warms, exposure to sunlight could have an immense impact on overall health. Dr. Roger Seheult, a critical care physician, pulmonologist, and associate clinical professor at the University of California and Loma Linda University schools of medicine, shared the benefits of sunlight exposure in an interview with Fox News Digital.

Seheult, who recently appeared on Dr. Andrew Huberman’s podcast Huberman Lab to discuss enhancing the immune system, noted that the light from the sun boosts our ability to regulate sleep, circadian rhythm, and mood.

Sunlight has been used for healing purposes dating back to the 1920s. Hospitals would transport patients to sundecks for periods of time to take in the sunlight and fresh air, according to Seheult. However, with advancements in modern medicine, doctors began to rely less on these holistic methods.

The sun’s ultraviolet B (UV-B) light produces vitamin D in the body, which is an anti-inflammatory and antioxidant that supports immune health, muscle, and brain function. In addition, sunlight produces infrared light, which has been shown to relieve pain and inflammation.

Just 15 to 20 minutes of sunlight exposure can help boost the immune system and potentially ward off chronic disease. However, concerns about sunlight leading to skin cancer may have caused decreased exposure. Seheult emphasized the importance of moderation and smart sun exposure to reap the benefits without risking skin damage.

Recent studies have found that spending more time outside in sunlight can actually reduce the risk of dying from all causes, including cancer. Dr. Richard Weller, a professor of dermatology at the University of Edinburgh, discussed the need to rethink the influence of the sun on overall health in a study published in the Journal of Investigative Dermatology.

Seheult encourages people to rethink the idea that the sun is harmful and to find a balance between modern medicine and holistic health trends. He recommends incorporating both approaches for optimal health benefits.

To benefit from infrared light without the risk of sunburn, Seheult suggests going outside and covering up for about 30 minutes, even during the morning or evening when the sun is setting. Taking short breaks to step outside into the light or a green space can also be beneficial for those who work indoors all day.

Incorporating sunlight and fresh air into daily routines can have significant health benefits that are not dependent on supply chains. Seheult emphasizes the importance of finding a balance between modern medicine and natural methods to promote overall well-being.

Overall, taking advantage of sunlight exposure in moderation can have a positive impact on immune health, mood, and overall well-being. So, as the weather warms up, don’t forget to step outside and soak in some beneficial sunlight.
