Alternating heat and cold flushes the body, calms the nervous system and turns one night's sleep into two. Here's the protocol.

Contrast therapy — alternating hot and cold exposure — is one of the oldest and most effective recovery tools, and it's making a comeback in elite combat sports for a reason.
The pump that flushes you Heat dilates your blood vessels; cold constricts them. Alternate the two and you create a vascular "pump" that moves blood and lymph, helping clear the metabolic waste that builds up after a hard session.
A simple protocol - 3–4 minutes hot (sauna or hot shower) — get genuinely warm. - 30–60 seconds cold (cold shower or plunge) — uncomfortable but controlled. - Repeat 3–4 rounds, always finishing on cold to leave the nervous system calm and alert.
More than muscles The bigger benefit is on the nervous system. Contrast exposure trains your stress response — you practice staying composed while uncomfortable, the exact skill you need in the championship rounds.
Recovery isn't passive. It's a session you do on purpose.
Done a few times a week, contrast therapy can turn a battered body around overnight.
