About

Sunwell began with a question raised inside Sweden’s automotive industry, where a sun simulator revealed measurable effects on human wellbeing. That question led to 25 years of research across engineering and human biology. Supported by leading experts and the Argynnis Group, we deliver safe, controlled sunlight to spaces built for recovery and healthier living.

How Vitamin D Supports Your Body & Health

Scientifically calibrated and clinically supported, S1 activates the body’s natural vitamin D production. It supports biological recovery and essential physiological functions through controlled light exposure.
