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.
Sunlight is not merely an environmental factor or a simple “stimulus,” but a precise biological signal that regulates circadian rhythms, hormonal activity, metabolism, and regeneration.
Oxidative stress does not arise suddenly or as the result of a single factor. It is a process linked to the everyday functioning of cells, mitochondrial activity, and the balance between physiological load and recovery. In this article, we take
For millennia, the Sun has shaped the rhythm of life and health. In traditional medicine, it functioned as a natural “clock of life,” regulating activity, rest, and bodily balance. Today, science confirms that without light, neither our circadian rhythm nor
In the latest episode of the Sunny Podcast, I speak with Dr. Anita Wasik – a scientist, herbalist and therapist who sees health as part of a larger ecosystem: the sun, soil, plants, and the human body.
Recently on the Sun for Life blog, we explored the history of light in medicine and the Asclepieia, places where light, nature and the rhythm of the day supported healing. Today, I invite you to one of them: Lissos on
Long before science emerged, the sun taught people how to live in harmony with nature and became one of the first tools for supporting health. In this part of the “Sunlight in Medicine” series, we return to the Bronze Age
For millennia, sunlight supported healing and health. Today, science confirms what earlier generations knew: without light, neither our bodies nor our minds can function properly. We return to the forgotten history of Light in human health.
The TARGET-D study, presented at the 2025 AHA Scientific Sessions, brings promising data for patients who have experienced a heart attack. Targeted optimisation of vitamin D levels may help reduce the risk of a recurrent heart attack. Here, we explain
What happens when the body starts sending signals that can no longer be ignored? In the third episode of the Sunny Podcasts, I speak with a couple who, after seventeen years in Scotland, decided to begin their life again from
Stress has become an inseparable part of modern life, affecting both the body and the mind. An increasing number of studies – including the GrassrootsHealth article – show that the key to mental resilience may be something as simple as…
How long do we want to live, and how long can we truly stay healthy? More and more scientists today agree that it’s not the length of life (lifespan), but its quality (healthspan), that should be our goal. How we
We spoke about distance, masks, and vaccines, yet hardly about light.
Now, with hindsight and new understanding, we realize it may have been one of our most overlooked allies in maintaining immunity.
