Our blog is a space for understanding how sunlight and UV radiation interact with the human body. We explore different aspects of light, from its role in everyday functioning to the risks associated with excessive exposure. We show how to approach light more consciously, taking into account both its significance and its limitations.
Explore with us how light fits into everyday life, discover different aspects of tanning, both in the sun and in tanning beds, and dive into scientific research that helps better understand sunlight, UV radiation, and the technologies related to it.
In June 2026, an international symposium dedicated to vitamin D and the biological effects of light took place in Homburg, Germany. Its second part, Biologic Effects of Light, was particularly interesting. During this session, scientists discussed UV radiation, dose, photoprotection,
Indoor tanning technology is evolving beyond session time alone. Discover how full-body LED systems, skin sensors, personalised programmes and red light are changing the way modern solariums manage light, comfort and individual exposure.
Every May, GrassrootsHealth Nutrient Research Institute celebrates Sunshine Month, an international educational initiative dedicated to raising awareness about the role of sunlight in human health. When the campaign began over a decade ago, the primary focus was vitamin D and
Ultraviolet (UV) radiation contributes to extrinsic skin aging called photoaging. Research over the past several decades has revealed that a higher intake of several specific nutrients corresponds with less UV induced skin damage, less photoaging, and less incidence of skin
It has been almost a year since the first article was published on Sun for Life. This past year has been a time of building the project. The beginning of spring feels like a natural moment to pause, reflect on
Sanatoria of the 19th and 20th centuries were places where, for the first time in modern history, light began to be treated as an element of therapy. In the era before antibiotics, it was sunlight, fresh air, and carefully designed
Can light change our chemistry, and with it, our entire life? In the sixth episode of the Sunny Podcast, we welcome Gilles Marin, a teacher of the Taoist tradition and founder of the Chi Nei Tsang Institute. We talk about
Hospitals are often associated with technology and sterility, but what if the most powerful medicine is still nature itself? More than 150 years ago, Florence Nightingale demonstrated that darkness could be more deadly than wounds and that direct sunlight was
In recent decades, the narrative surrounding ultraviolet (UV) exposure has been dominated by fear, primarily in the context of skin cancer. While the risks associated with excessive exposure are real and well documented, a growing body of scientific evidence shows
Is a lack of sunlight merely a seasonal discomfort, or rather a measurable public health issue? Suicide statistics have long revealed a paradox: the highest rates occur not in winter, but in spring.
The Industrial Revolution was the first moment in history to cut people off from natural light. Life shifted into cities, factories, and enclosed spaces. This article explores how the loss of sunlight affected public health and became the starting point
What supports women’s health during pregnancy and long after? In this episode of the Sunny Podcast, I talk with Jen Aliano from GrassrootsHealth about vitamin D, sunlight, and key nutrients that play an essential role in the health of mothers
