Cryotherapy Pre-Session Checklist
What to do in the 24 hours before your first chamber session
Most cryotherapy facilities give you a one-line pre-session instruction at booking — "don't eat too much beforehand" or "avoid alcohol" — and assume that's enough. It isn't.
How you prepare for a cryotherapy session affects how the session feels, what your body actually gets from it, and how quickly you recover afterward. This guide is the practical version of what an experienced chamber operator would tell you if they had the time.
It's written by KRYO KUBE, an Australian electric cryotherapy chamber manufacturer. We built the chamber experience to be as low-friction as possible — but no chamber design can substitute for showing up prepared.
Quick navigation
1. The day before
Sleep
Cryotherapy works on the autonomic nervous system, and so does sleep. Going into a session sleep-deprived doesn't mean the session won't work — but the recovery and mood benefits afterward are blunted when your nervous system is already running depleted.
Aim for 7+ hours the night before your first session. If you can't get that, postpone the session if it's flexible.
Hydration
Start hydrating the day before, not the day of. The cold stimulus shifts blood volume from your extremities to your core, and being dehydrated amplifies the cardiovascular load. Drink steadily across the day rather than chugging water just before your session.
A reasonable target: an extra 500ml beyond your normal water intake on the day before.
Alcohol
Skip alcohol for at least 24 hours before your first session. This isn't optional. Alcohol impairs blood vessel reactivity, dehydrates you, and significantly increases the risk of adverse responses to extreme cold. Reputable facilities will refuse a session if they suspect you've been drinking.
If you drink regularly, plan your first session for a morning after a fully sober night.
Caffeine
Caffeine is fine the day before. It's actually fine the morning of too, in normal amounts. We'll cover that below.
Skincare
Avoid harsh exfoliation, chemical peels, or aggressive skincare products on the skin areas that will be exposed in the chamber, for at least 48 hours before. Disrupted skin barrier function makes cold exposure feel sharper and increases minor irritation risk.
If you've had a recent professional skin treatment (microneedling, IPL, peel) within the past 72 hours, reschedule the session.
2. The morning of
Wake-up timing
Try to be awake for at least 90 minutes before your session. Cryotherapy stimulates a sharp autonomic response, and arriving still half-asleep blunts the experience and the benefits. Walking, light movement, and natural light exposure in the hour beforehand all help.
Shower considerations
If you shower the morning of, finish at least 60 minutes before your session, and dry yourself completely — including hair if it's long enough to retain moisture. Any moisture on the skin or in hair freezes essentially instantly at chamber operating temperature, which is uncomfortable at minimum and can cause minor cold injury.
If you've sweated during morning exercise or your commute, you'll need to towel off thoroughly at the facility. Most operators have hairdryers available for this exact reason.
Skincare on the morning of
Skip moisturisers, body lotions, and oils for the few hours before your session. These can refreeze on the skin and reduce the chamber's heat-transfer efficiency. The skin should be clean and dry.
Antiperspirant and deodorant are fine.
Medications
Take regular prescription medications on your normal schedule. Don't skip morning medications because of a cryotherapy session — that creates more risk than the cold does.
If you've started a new medication in the past two weeks, mention it to the operator before your first session.
3. What to bring
For a first session at a commercial facility, you'll usually need almost nothing — most facilities provide everything required.
What the facility typically provides
Dry socks (cotton or wool)
Gloves (light, dry)
A robe or wrap for entering and leaving the chamber
Hairdryer and towels
A private changing area
What you should bring
A water bottle (drink before and after, not during)
Loose, comfortable clothes for after the session
Hair tie if you have long hair (you'll want hair away from neck and face)
A book or phone if you have a buffer time before or after
What you don't need
Special cryotherapy gear (it's a marketing concept that doesn't exist as a real category)
A change of underwear (you'll typically be in what you arrived in, or in whatever the facility provides)
A heat source for afterward (your body warms naturally and quickly)
4. What to wear
Inside the chamber
The standard is as little as possible. Most facilities specify underwear or swimwear, plus the provided socks, gloves, and (sometimes) ear coverage.
The reason for minimal clothing is heat transfer efficiency. The chamber works by cooling the skin, and clothing — particularly damp clothing — interferes with this. The colder the chamber, the more important this becomes.
Specifically:
Men: underwear or short shorts
Women: underwear/bra, swimwear, or naked, depending on facility policy and comfort
Everyone: dry socks, gloves, often a head/ear band
Never: jewellery, watches, piercings, anything metal touching skin
What to wear arriving and leaving
Loose, comfortable clothes that are easy to get in and out of. You'll change at the facility, so what you arrive in is whatever you'd happily change out of and into a robe in a small private room.
In Australian winter, layered clothing is sensible — you'll feel hot immediately after the session as your body rewarms aggressively, and you'll want to be able to take a layer off without overheating.
5. Eating and hydration
Before the session
Don't go in hungry, don't go in stuffed. A light meal 60–90 minutes before is ideal. Empty stomach can leave you light-headed during the autonomic response; a heavy meal diverts blood to digestion when you want it free to respond to the cold.
Good pre-session foods: oats, eggs, fruit, light protein, anything that digests cleanly. Avoid spicy food, heavy carbs, or anything you know upsets your stomach.
Hydration
Drink water steadily for two hours before, then taper in the final 30 minutes. You don't want a full bladder during the session — there's no exit-and-re-enter, and three minutes feels longer when you need a bathroom.
Caffeine
Normal caffeine intake is fine. A coffee 60 minutes before a session is actually beneficial for some people — it sharpens alertness and works synergistically with the cold-induced norepinephrine response. Don't double your normal intake, but don't skip it either if it's part of your routine.
Immediately after
Drink water within 15 minutes of stepping out. Your body has been redistributing blood volume aggressively and your kidneys will catch up — you'll likely need a bathroom within the hour. This is normal.
6. What to skip in the 24 hours before
Hard
Alcohol (any amount)
Recreational drugs of any kind
Intense exercise within 4 hours before (cryotherapy after exercise is fine; right after exercise creates compound autonomic load)
New medications you haven't established tolerance to
Saunas or extreme heat exposure within 6 hours before
Soft
Heavy meals within 90 minutes before
High-stress meetings or events immediately before (your nervous system needs some baseline composure)
Aggressive skincare treatments
Things people think they should skip but don't need to
Regular coffee
Normal supplements
Normal exercise the day before
Sex (no, it doesn't matter)
Cold showers or cold plunges within a few hours before — but spacing them apart by 4+ hours is better than stacking
7. Mental preparation
Your nervous system response to the cold is real, but it's also partly modulated by what you expect.
People who walk in dreading the session usually find the first 30 seconds harder than people who walk in curious. People who walk in trying to "tough it out" usually find their breathing more ragged than people who walk in expecting to breathe steadily through it.
A few framings that help:
It's only three minutes. Three minutes is shorter than a song on the radio.
The intensity peaks in the first 30 seconds, then fades. Your skin adapts faster than you expect.
Your body knows what to do. Cold is an evolutionarily ancient stimulus. You don't have to do anything heroic — just stand and breathe.
You can leave at any time. The door isn't locked. Most people who plan to bail stay in. Knowing you can leave removes the panic loop.
If you're a person who responds well to breathwork, slow nasal breathing through the session — in for four counts, out for six — works well. Don't hold your breath; don't hyperventilate; just breathe steadily.
8. What to expect immediately after
The first sensation stepping out is warmth. Your body is rewarming the surface skin aggressively and the contrast with the chamber air feels good.
Within five minutes:
Skin returns to normal temperature
Mild flushing across the chest and shoulders is common
A slight tingling in fingers and toes as circulation re-equilibrates
An elevated, alert mood — sometimes pronounced enough to feel almost euphoric
Within thirty minutes:
Significant mood lift in most first-time users
Sharper mental clarity
Sometimes mild thirst or appetite shift
Within two hours:
Most acute effects taper
A subtle background sense of wellbeing that can last the rest of the day
The first session is usually the most pronounced experience because everything is novel. Subsequent sessions feel less extreme but produce more durable cumulative benefit.
9. The 24 hours afterward
Cryotherapy is not a treatment you need to recover from — but how you spend the hours afterward affects how much you get out of it.
What helps
Movement. Light walking or gentle activity in the hour afterward extends the circulation benefits
Hydration. Continue drinking water steadily; your kidneys will be active
Real food. A proper meal within two hours supports the metabolic activation the session triggered
Sleep. If you do an evening session, prioritise sleep — cryotherapy appears to improve sleep quality, and you should let it
Tracking. Note how you feel 1 hour, 4 hours, 12 hours, and 24 hours afterward. Patterns emerge over multiple sessions
What hurts
Alcohol within 4 hours afterward — undoes much of the autonomic benefit
Excessive heat exposure (sauna, hot bath) within 2 hours — the temperature contrast is uncomfortable and dilutes the cold-induced responses
Cold plunges or ice baths within 4 hours — autonomic overload, not synergy
Skipping water — you'll feel suboptimal for the next 12 hours
When to schedule the next session
For first-time users: leave at least 24 hours between your first two sessions. This lets you assess how your body responded before doubling down.
For ongoing use: 2–3 sessions per week is the most evidence-supported protocol. Daily sessions are appropriate for specific short-term goals but aren't necessary for general wellness use.
10. Red flags to mention to your operator
Tell the operator before the session, not after, if any of the following apply:
You've had any cardiovascular event in the past 6 months (heart attack, stroke, surgery, new arrhythmia diagnosis)
You're pregnant or think you might be
Your blood pressure has been running high recently (above 160/95) and you're not sure why
You have a pacemaker or any implanted electrical medical device
You've started a new medication in the past two weeks — especially blood pressure medications, blood thinners, or stimulants
You have Raynaud's syndrome or any cold-sensitivity diagnosis
You're feeling unwell — early-stage flu, fever, infection
You're significantly hung over — alcohol metabolites stay in the system longer than people think
You've had any cold injury before — frostbite, frostnip, chilblains
A good operator will sometimes refuse a session based on what you tell them. That's a sign you're at a responsible facility. Take it seriously.
How KRYO KUBE chambers are designed to reduce preparation friction
Most of the preparation requirements above exist because cryotherapy is genuinely a powerful physiological stimulus. None of them go away because of which chamber you use.
But several friction points specific to certain chamber types are absent in KRYO KUBE chambers:
No nitrogen exposure — no need to remove head from chamber, no respiratory considerations, no oxygen-displacement risk in the room
Dry cold, sealed system — no chamber-side humidity to worry about, no moisture freezing on the chamber walls dripping back on you
Consistent temperature delivery — what the chamber is set at is what the chamber delivers, every session
Standard 10A wall outlet — chamber starts up reliably without three-phase power conditioning delays
Quiet operation — you can actually breathe and think clearly during the session with noise cancelling head phones, and listen to your favourite music.
The chamber design philosophy was: remove every friction point we could engineer away, leaving only the parts that genuinely require client preparation.
A note on what you'll find at a KRYO KUBE-equipped facility
Cryotherapy operators using KRYO KUBE chambers typically charge $35–$60 per session — significantly less than the $99+ traditional facilities have to charge to recover their higher operating costs. The technology is delivering the same therapeutic temperatures; the price is lower because the chamber's underlying cost structure is lower.
If you're shopping for a facility, the question worth asking is: what chamber do you use, and what are you charging? It's a clean way to identify facilities running modern equipment versus those running expensive old 3 Phase legacy systems.
The honest summary
Showing up prepared makes the experience better. The preparation isn't extensive — sleep, hydrate, eat lightly, skip the alcohol, arrive dry. Most of it is common sense once you understand why each piece matters.
Cryotherapy isn't a delicate or fragile experience. Your body is well-equipped to handle the cold. Preparation just helps you get the most out of three minutes.
