As spring arrives and time warms up, Sun exposure could have a huge impact on global health.
Dr. Roger Seheult, intensive care doctor, pulmonologist and clinical professor associated with the University of California and medical schools at the University of Loma Linda, shared the advantages of sun exposure in an interview with Fox News Digital.
Seheult, who recently appeared on Dr. Andrew Huberman “Huberman Lab” podcast to discuss Improve the immune systemnoted that sunlight stimulates our ability to regulate sleep, circadian rhythm and mood.

“So many people have a seasonal emotional disorder, and it is a manifestation of the lack of sun during the winter,” he said.

Sun light healing properties
From the 1920s, health professionals took advantage of the exposure to light to promote healing.
Hospitals have used sun tones, where patients could be transported during periods to absorb sunlight and fresh airAccording to Seheult.

But with the development of penicillin and other progress in modern medicine, doctors relied less on holistic methods, he said.
Ultraviolet light B (UV-B) from the sun produced vitamin D In the body by causing a chemical reaction in the skin, noted Seheult.

Vitamin D is an anti-inflammatory and a known antioxidant that supports immune healthMuscle and brain function, according to Mayo Clinic.
The sun also produces infrared light, which has proven to relieve pain and inflammation.
According to Seheult, only 15 to 20 minutes of sun exposure can help stimulate the immune system and potentially purge chronic diseases.
Balance risks and advantages
Warnings from sunlight health professionals leading to skin cancer may have caused a decrease in exposure, the doctor suggested.
“Admittedly, if we go out for too long in the sun for a certain time without protection, we can get these types of skin damage,” he said.
“There are advantages to go out in the sun, if it is done in moderation and if it is intelligently done.”
But the doctor said that some recent studies have shown that the more time outside the sun, the less people should die of all causes, including cancer.
Dr. Richard Weller, professor of dermatology at the University of Edinburgh, published an article in the Journal of Investigative Dermatology in August 2024, discussing this data and the need to rethink the influence of the sun.
Why the end of daylight time can negatively affect your health
“UVRs are a carcinogenic of the skin, but no study links sun exposure to increased mortality all causes of causes,” Weller wrote in the study summary.
Walking in green spaces can offer an even brighter exposure, because the trees, leaves and plants are “very reflected in infrared light”. (istock)
“Increasing evidence shows that sunlight has health benefits through independent vitamin D routes, such as photomobilization of nitric oxide from skin reserves with a reduction in cardiovascular morbidity, “ He wrote.
“Sun light has important systemic health benefits as well as risks.”

Seheult has accepted, encouraging people to “rethink the idea that the sun is a deadly laser and that there are in fact advantages to go out in the sun, if it is done in moderation and if it is done intelligently”.
People who are with clear or sun -sensitive skin can wear clothes, hats and other protective equipment while benefiting from the advantages.
“The infrared light, because it is a light with low wavelength and low energy, is capable of penetrating not only through your skin and deeply in your body, but it is also able to penetrate very easily through clothes,” said Seheult.
Vitamin D of sunlight acts as an anti-inflammatory and antioxidant, helping to support immune health, muscles and the brain. (istock)
“If they always go out, they will get a little infrared light, even in this context, and not be likely to be done (burned). So you don’t need to have bare skin for sun exposure. “”
Sun light is also always present on cloudy and rainy days and in urban areas, noted Seheult.
Why higher UV index numbers are more dangerous during sun exposure
“The amount of light inside a building (is) generally no more than 100 lux,” he said. “When you go out on a brilliant and sunny day, it’s 100,000 lux. It’s 1,000 times brighter.”
Although this exhibition is reduced on cloudy days or in winter, it will not be “almost as low” as the interior lighting, added Sehuelt.
“Children spend so much time inside,” said Seheult. “Any kind of movement that we make to go out will be very beneficial.” (istock)
To harvest the advantages of risk -free infrared light, Seheult recommended to go out And covering about 30 minutes, even in the morning or evening while the sun sets.
“These are moments when there is an abundance of infrared light, much more than you would in your home,” he said.
“All you need is about 15 to 20 minutes of exposure to infrared light … and we see effects that last days.”
For those who work in an office and spend their hours of clarity inside, Seheult suggested taking short breaks and going out in the light or a green space.

“All you need is about 15 to 20 minutes of exposure to infrared light at the mitochondria, and we see effects that last days,” he said.
Mixture of holistic and modern methods
Seheult shared his hope for a balance between modern medicine – including progress such as oxygen of medical quality and antibiotics – and holistic health trends.
“There are certainly modern inventions and things that are very beneficial for the human body,” he said. “What I would like to do is integrate both.”

“There is a disadvantage to entirely depending on the things that need and require supply chains, especially in pandemics,” he said.
“Sun light and fresh air … are not things that depend on supply chains. We have sunlight accessible most of the year.”
