Restless Legs: When the Night Becomes a Burden

Tingling, twitching, and the urge to move – especially at night. Millions of people suffer from Restless Legs Syndrome (RLS), and peaceful sleep often seems out of reach. Many have tried medications, often with unpleasant side effects, and are now looking for a gentler, more natural solution.


Targeted cooling is a proven method to ease symptoms: it slows nerve signals, relaxes the muscles, and interrupts the sensation of restlessness. The result? Less discomfort – and more restful nights.


The good news: Cooling can bring real relief – naturally and without medication. That’s exactly where Kalter Bruder® comes in.
