Safety and health benefits
Health benefits of cold plunge
Regular cold plunge improves blood circulation by constricting and dilating blood vessels, strengthens immune system by increasing white blood cells, reduces inflammation and muscle soreness post-workout, increases energy and mental clarity by releasing adrenaline and endorphins, improves sleep quality by lowering body's core temperature, and builds mental resilience through controlled stress exposure. Combined with sauna (contrast therapy) these effects are amplified. Norwegian research shows 2–3 sessions per week yield best results.
Safety tips for beginners
Start gradually: 30 seconds first time, build to 1–3 minutes over weeks. Consult doctor if you have heart, blood pressure, or circulation issues. Never submerge head underwater initially—keep head above water until body adapts. Breathe calmly and deeply, avoid hyperventilation. Always have warm sauna, shower, or dry clothes available after. Never go alone in winter—join winter swimming club for safety. Stop immediately if you lose feeling in extremities or feel discomfort.
