01 · Four ways to plunge
Pick the access mode that fits your level.
R1SE runs cold across both Kelham Urban Spa and Brook Place. Guided experiences for newcomers; unguided access for members who know the routine.
Guided Fire & Ice
Scheduled sessions, both locations
Best for first-timers and members who want a facilitated experience.
A spa facilitator coaches activating breathwork before you enter the water, advises on water temperature and safe duration, and stays on the floor for the duration of the session. The structure makes contrast therapy (sauna → cold → repeat) flow naturally. Recommended as your first cold-plunge experience at R1SE.
Wellness Experience
Scheduled group sessions
Best for community feel and a fully-coached session that combines cold with breathwork, sound and recovery.
Our flagship guided experience. Combines cold plunge with breathwork, sound, and recovery in a structured group session led by a facilitator. Powerful for first-time members and a great regular ritual for members deeper into the practice.
Unguided Brook Place
Open hours, Brook Place
Best for members who've learned the routine and want maximum frequency.
Once you know how to prepare, plunge, and recover, the unguided plunges at Brook Place let you stack cold into your routine without needing a scheduled session. Most members move to unguided access after 3–5 guided experiences.
Daytime Kelham
Daytime open access, Kelham
Best for members combining ice bath with sauna, HBOT, red light, or compression in a longer recovery stack.
Kelham Urban Spa during the day — unguided access to the cold plunges as part of the wider spa floor. Use alongside infrared sauna, HBOT, red light or compression for a full recovery stack session.
02 · A session, step by step
What actually happens, from arrival to afterglow.
Arrive hydrated and unhurried
Drink 250–500ml of water 30 minutes before. Avoid heavy meals within 90 minutes. Skip caffeine if you're particularly sensitive — the norepinephrine surge already delivers the alertness. Arrive a few minutes early so the cold isn't the first stressor of your day.
Breathwork prep (2–3 min)
On Guided Fire & Ice and Wellness Experience sessions a facilitator coaches activating breathwork — typically 2–3 minutes of box breathing or Wim Hof-style breath — before you enter the water. On unguided sessions, do this yourself: a few rounds of slow nasal breathing to prime your nervous system.
Enter calmly
Step in slowly. The cold shock response — rapid breathing, involuntary gasp, racing heart — lasts 60–120 seconds. Don't fight it. Focus on long slow nasal exhales. Within 2 minutes your body settles and the dopamine and norepinephrine surge takes over.
Stay 1–3 minutes
Two to three minutes is plenty for most members; 30–60 seconds is enough if you're new. More is not necessarily better — the adaptive signal saturates quickly and longer sessions add risk without much extra benefit. Trust the protocol.
Exit slowly
Move slowly and mindfully on exit. Don't shower immediately — let the parasympathetic rebound unfold. Towel off, sit warmly dressed for 5–10 minutes. Light movement helps circulation return.
Capture the post-cold window
The 30–60 minutes after exit is when the dopamine elevation peaks. Many members find this window is when they do their best focused work, hardest conversations, or most creative thinking. Plan for it.
03 · Protocols
Match the protocol to your goal.
Søberg Minimum
4–5× per week
The minimum-effective-dose protocol (Søberg 2021, Cell Reports Medicine). Sustains brown adipose tissue activation, supports metabolic adaptation, and delivers the mood and immunity benefits. The realistic floor for serious practice.
Daily Reset
Daily
Short, frequent cold exposure focused on the dopamine and mood signal. Easier to sustain than longer sessions. Pair with morning breathwork for the strongest cognitive after-effect.
Recovery Protocol
Within 24h of training
The Bleakley 11/11/11 post-exercise protocol — 11–15°C for 11–15 minutes. Best for endurance recovery and DOMS reduction. Avoid within 4h of strength training if hypertrophy is your goal.
Wim Hof
2–3× per week
The Kox 2014 protocol — structured breathwork before cold exposure. Modulates inflammatory response (PNAS evidence). Powerful but technical — book Guided Fire & Ice for the first attempts.
