The true Sonnenfreund is no longer the naked man on a beach in Sylt. It is the toddler in a Berlin Kita (daycare), lathered in SPF 50+, wearing a floppy hat and a long-sleeved rash guard, playing in a sandbox that is half-shaded by a UV-blocking sail.

To them, clothing was a prison. Brick walls were an abomination. The true path to physical and moral purity was —specifically, sunlight.

This was the era of the Sonnenstudio (tanning salon). Germany became a European capital of indoor tanning. To be a Sonnenfreund was to be active, sexy, and modern. The phrase "Schönes Wetter, schöne Leute" (Good weather, good people) became a mantra. The Kinder der Sonne were simply the lucky ones living on the Mediterranean coast, blessed by latitude. Today, to call someone a Sonnenfreund carries a knowing, ironic wink. We know better now.

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.

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.

Germany, like Australia, has seen a steady rise in skin cancer rates. The Sonnenfreund of the 1980s is now the dermatologist’s best customer. The government has banned tanning beds for minors, and the WHO classifies UV tanning devices as Group 1 carcinogens.

In this context, being a Kind der Sonne was not just about a tan. It was a racial marker. Those who could not tan (the very pale or sickly) or who refused to participate (those hiding in factories or ghettos) were deemed degenerate. The sun, once a symbol of universal health, became a tool of exclusion. After WWII, the terms shed their Nazi baggage and returned to hedonism. The 1960s and 70s saw the rise of the Sonnenfreund as a lifestyle brand. With affordable package holidays to Mallorca and the Canary Islands, the pale Northern European skin became a mark of poverty (the factory worker), while the bronze tan signaled leisure and wealth.

Nowhere is this dichotomy more visible than in the German cultural concepts of the (Sun Friends) and the Kinder der Sonne (Children of the Sun). At first glance, these terms evoke images of beach holidays and tanning salons. But a deeper look reveals a complex history—one that swings from utopian health reform to dangerous pseudoscience, and finally, to the modern existential crisis of ozone holes and skin cancer. The Naked Pioneers: The First Sonnenfreunde The modern story of the Sonnenfreunde begins not in the 1970s tanning boom, but in the Lebensreform (Life Reform) movement of 19th-century Germany and Switzerland. These were radical nudists, organic farmers, and gymnasts who believed that industrial society had made humanity sick.

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.

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.

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.

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.
