Cold applications reduce inflammation and relieve pain.
- Mental clarity and focus
Intensive cold improves cognitive function and increases the ability to concentrate.
- Strengthening the immune system and metabolism
Exposure to cold trains the immune system and activates the metabolism, which increases the body's resistance.
- Stress reduction and emotional well-being
Cold therapy activates the parasympathetic nervous system, which reduces stress and improves emotional balance

Combien de temps faut-il prendre un bain froid ?
The recommended duration is 2 to 15 minutes, depending on your experience with cold, your physical condition, and the purpose of the application. Beginners should start with short intervals and increase gradually.
What are the health benefits of an ice bath?
An ice bath offers a variety of health benefits: It reduces inflammation, supports muscle recovery after sport and strengthens the immune system. It also promotes blood circulation, activates the metabolism and can improve the quality of sleep. Mental strength is also trained through regular cold stimuli - consciously dealing with the cold strengthens your own resilience and self-control.
In addition, an ice bath contributes to general well-being, increases resistance to cold and has an antioxidant effect by reducing oxidative stress in the body.
Important: Staying too long or in water that is too cold can lead to circulatory problems, hypothermia or frostbite. People with pre-existing medical conditions should seek medical advice beforehand.
Who are ice baths particularly suitable for?
Ice baths are ideal for athletes, biohackers, fitness enthusiasts and anyone who wants to boost their physical and mental health. People with chronic fatigue, high stress levels or a weakened immune system also benefit from cold therapy.
Ice baths are particularly effective for sore muscles, micro-injuries or after intensive training sessions - they inhibit inflammation and alleviate the perception of pain. This accelerates regeneration and promotes long-term performance.
People with chronic pain conditions or inflammatory diseases such as rheumatism or fibromyalgia can also benefit from regular, controlled cold applications - always in consultation with medical specialists.
When is the best time for an ice bath - before or after training?
An ice bath after training is ideal for regeneration: it reduces muscle soreness, inhibits inflammation, promotes blood circulation and speeds up recovery. It has a particularly relaxing and regeneration-promoting effect after intensive sessions or competitions.
A short ice bath (approx. 1-2 minutes) before training can have an activating effect: it promotes mental focus, stimulates the metabolism, activates the cardiovascular system and increases muscle tension - ideal before a competition or if you are mentally tired.
Important: If you want to build muscle mass (hypertrophy), you should refrain from taking an ice bath immediately after strength training, as it can inhibit muscle growth in the short term. An interval of several hours or abstinence on these days is recommended.
How do you get used to the cold in an ice bath?
The body can adapt through regular, brief exposure to cold. Start with 30-60 seconds at 10-15 °C and increase gradually. Cold showers are good preparation. Important: Breathe calmly, do not tense up. Tip: Keep your hands and arms above the water to start with - this makes it easier to get started, as hands are particularly sensitive to cold. Over time, you can increase the depth of immersion.
