Deliberately alternating heat (sauna) and cold (plunge) within one session. It boosts circulation, reduces inflammation, speeds muscle recovery, elevates mood, supports immune balance, and promotes better sleep and stress resilience.

How it works
• Heat: vasodilation—blood vessels widen, circulation increases.
• Cold: vasoconstriction—blood is redirected to vital organs.
The alternation trains blood vessels, flushes toxins, reduces inflammation and boosts circulation.

Key benefits
– Enhances blood and lymph flow
– Speeds muscle recovery, reduces soreness
– Raises heart-rate variability (HRV) and vagal tone
– Elevates mood via endorphins and noradrenaline
– Supports immune and nervous-system balance
– Promotes better sleep and stress resilience

For whom? Athletes, biohackers, the stressed, those with poor circulation—anyone seeking deep recovery and mental clarity.
