This has given rise to the New Sonnenfreund : the biohacker. These are the tech executives wearing UV monitors on their wrists, timing their sun exposure to the minute. They use apps that tell them exactly when to get 15 minutes of midday sun (for vitamin D) and when to run for shade (to avoid UVA aging). Perhaps the purest Kinder der Sonne left are the children of the global migration crisis. In a cruel irony, many refugees from sun-scorched zones (Syria, Afghanistan) arriving in Germany suffer from severe vitamin D deficiency because they are suddenly trapped indoors, their skin covered, in a land of grey skies.
Groups like the Freilichtpark (Open Air Parks) sprang up around Lake Constance and in the Lüneburg Heath. They called themselves Sonnenfreunde . Their creed was simple: UV radiation was a disinfectant. Sunlight cured rickets, tuberculosis, and even moral decay. This wasn't just sunbathing; it was a spiritual baptism by solar fire. The concept of Kinder der Sonne has a more problematic heritage. While the Sonnenfreunde were generally apolitical hedonists, the "Children of the Sun" ideology was weaponized by the eugenics movement of the early 20th century, culminating in its adoption by the Nazi regime.

In the pantheon of human cultural movements, few forces have been as simultaneously life-giving and life-threatening as the sun. From the Aztecs offering hearts to the solar deity to Victorian-era physicians prescribing “heliotherapy” for tuberculosis, our relationship with our nearest star has always been a blend of worship and science.

The love of the sun persists. But today, being a Kind der Sonne means respecting its power. We are still children of the star—but we have finally grown up enough to wear sunscreen. Sonnenfreunde and Kinder der Sonne are linguistic fossils. They trace a path from utopian nudism through fascist aesthetics to holiday hedonism and finally to medical caution. To love the sun today is to negotiate a treaty: you may have its warmth and light, but you must pay your respects with high-SPF protection and regular skin checks. The sun is no longer our friend; it is our beautiful, dangerous parent. Perhaps the purest Kinder der Sonne left are
The Nazis adored the solar aesthetic. Leni Riefenstahl’s films are filled with Aryan youths—blonde, muscular, bronzed—emerging from the mist as Kinder der Sonne . The regime promoted massive "light and air" baths, believing that sunlight would strengthen the Volkskörper (national body) and weed out the weak.
To them, clothing was a prison. Brick walls were an abomination. The true path to physical and moral purity was —specifically, sunlight.
Yet the psychological drive remains. Vitamin D deficiency (the "winter blues") is a serious health issue in northern latitudes. We need the sun to live, but too much kills us.
