A cold plunge tub uses the science of cold water immersion to deliver full-body recovery through powerful physiological effects. When filled with water between 3°C and 5°C, it offers a much deeper and more targeted impact than cold showers or ice packs. Immersing your body in cold water activates muscle recovery, reduces inflammation, and promotes circulation — all without chemicals or active effort.

🔧 How It Works – Step by Step:

1. Full-Body Immersion
   Step into the cold plunge tub. Your skin is instantly exposed to water around 3–5°C, activating sensory and vascular responses.

2. Rapid Heat Extraction
   Cold water absorbs body heat quickly through direct contact. This process is called conduction, and it cools your entire body evenly.

3. Vasoconstriction Response
   Blood vessels narrow (vasoconstriction), reducing swelling, inflammation, and perceived pain. After the session, blood flow rebounds, flushing out metabolic waste.

4. Chiller Integration for Precision
   With a connected cold plunge chiller, the water stays cold automatically — no ice, no daily maintenance. Just set your target temperature and relax.

5. Mental & Hormonal Reset
   The shock of cold triggers endorphin release, lowers cortisol, and sharpens focus. Many users also pair it with a sauna for contrast therapy.
