Regeneration Turbo.
Cristiano Ronaldo does it. LeBron James too. And even Novak Djokovic, Mbappé, and Manuel Neuer regularly take ice baths after training. Why? Because it works. Ever since Sebastian Kneipp proved medically 200 years ago that regular ice baths promote health, the trend has made a strong comeback. Whether for mental health or quick recovery – social media is full of squealing and groaning athletes bravely diving into the ice.

HOW DOES COOLING WORK?
Cooling is a proven method to enhance recovery after intense physical activity. It triggers physiological responses in the body that help reduce inflammation, relieve pain, and speed up the healing process.
Reduction of Inflammation and Swelling
Cold therapy causes blood vessels to constrict (vasoconstriction), which reduces blood flow to the affected areas. This leads to a decrease in inflammation and swelling, which are often caused by microtraumas in muscles and tissues after intense exertion. Once the cooling effect subsides, the blood vessels dilate again (vasodilation), improving circulation and supporting the healing process.
Relief from Muscle Soreness
Cold therapy can help alleviate delayed-onset muscle soreness (DOMS), which typically occurs 24 to 48 hours after...
This is where our Kalter Bruder® Relax gel makes a difference. Specially formulated for a long-lasting cooling effect, its unique recipe harnesses the fresh gel of the aloe vera plant and arnica, both known for their anti-inflammatory and soothing properties. Key ingredients like menthol and camphor enhance the cooling effect, helping to relieve pain and reduce swelling.
Kalter Bruder® offers a practical and efficient way to harness the benefits of cold therapy for targeted sports recovery. Thanks to its cooling effect, the gel provides gentle and consistent deep cooling, helping to relieve muscle discomfort without damaging the skin or restricting mobility.
