How Long to Ice Bath, How Often and When to Do It

How long should your first ice bath be?

The answer fits in one cautious number: 1 to 2 minutes. Lower yourself into the water gradually, then sit on the water cushion with your back straight and knees bent, the water up to your shoulders depending on your height. Breathe calmly and keep your head above the water for the whole session. Someone attentive stays next to you from start to finish. If you feel dizzy, have chest pain, go numb or start shivering uncontrollably, get out right away, even if the first minute is not up yet. A good first session is short, with someone by your side.

Why so much caution? According to the RNLI, the UK's sea rescue charity, cold water shock can occur in water at 59°F or below: it takes your breath away, with uncontrolled gasping, and makes the heart beat faster. The temperatures often quoted for an ice bath sit around 50 to 59°F. That is a concrete reason to get in slowly, to start with less cold water and a short session, and never to be alone.

Adding time week by week

Once your first few sessions go by without discomfort, you can lengthen them very gradually. The simplest method is to change only one thing at a time: a little more time, or slightly colder water, never both on the same day. At each session, write down the water temperature you measured and the minutes you spent in the water, then compare your notes from one week to the next. This log describes your own practice: there is no level to reach, no duration to hit and no result to expect.

Some sessions will be shorter than the one before, and that is not a failure: how the cold feels varies from day to day. When in doubt, go back to 1 to 2 minutes. The exit rule stays the same whatever duration you have already reached: at the first sign of discomfort, you get out, and the person with you stays until the very end.

How often should you take an ice bath?

No frequency is recommended here as better than another. Some people like a session at a set time, others prefer a cold plunge now and then, when they feel like it and their calendar allows. The rhythm is a matter of your routine and your comfort, not an imposed schedule, and it can change with the seasons or from one week to the next. The useful yardstick is practical: a frequency that always leaves you someone available next to the tub, time to warm up afterward and time to look after the water without rushing.

Frequency has a hands-on side too. The supplier's text advises changing the water every 10 to 15 days, and the tub must be dry before you fold it. Between sessions, the lid stays closed, which also keeps leaves and dust out of the water. If you add ice, do it just before your bath. For any health question about how often to plunge, a doctor is the one to answer.

What time of day, before or after a workout?

Morning, evening, before or after a workout: it is a question of personal scheduling, and no effect is promised or compared from one time to another. The right criteria are concrete. Can someone stay beside you for the whole session? Do you have time to dry off and dress warmly right afterward? Is the tub set on level ground that can bear its load, somewhere you can drain it without flooding the room? If the answer to any of these is no, pick another time slot.

After training, many people fit the ice bath into their routine as one more step, like a shower. Many people say they like the feeling of freshness, but choosing the hour remains a matter of your calendar. In summer, the water warms up over the day: a closed lid, a shaded spot for the tub and ice added just before your bath help keep it cold.

Warming up after an ice bath

Getting out deserves as much attention as getting in. Before you even step in, set a towel and dry clothes within reach, next to the tub rather than inside the house. Climb out slowly, without sudden moves, putting your feet down on dry ground, then dry off completely. Pull on several warm layers, a beanie and socks, and move gently: walk a few steps, swing your arms, stay active without effort or hurry. The person with you stays there while you get dressed.

As for the tub, close the lid as soon as you are out: when it is not in use, it stays covered, and it is drained whenever nobody can watch it. To empty it, use the side drain hose with its valve or the bottom plug, outdoors, in a shower or over a floor drain. Never tip it over when it is full: the support tubes could slip.

Who should ask a doctor first, and the safety rules

Before a first ice bath, see a doctor if you have heart disease, high blood pressure, a heart rhythm disorder, a circulatory disorder (including Raynaud's syndrome), diabetes or epilepsy, if you are pregnant or if you are under medical treatment. This guide gives no medical advice: it describes a practice and its rules. Questions about duration, frequency or temperature that concern your health belong with a doctor, not with a shop. The rules below apply to every session, the first as much as the hundredth.

Set the tub on level ground that can bear the load: full, it holds about 730 lb of water, plus the person; on a balcony or an upper floor, ask your building manager, landlord or HOA what load is allowed. If you want a tub for this routine, Ice Bath Tub sells a single round, foldable, insulated tub with a lid, as a complete kit (what's in the box: the tub and its 6 tubes, lid, dust cover, pump, cushion, drain, patches and carry bag), shipped free from stock in your region.

• Never alone: someone present and attentive nearby.
• No alcohol, drugs or medication that makes you drowsy before or during the bath.
• Get in gradually, breathe calmly, start with 1 to 2 minutes and keep your head above the water.
• Get out immediately if you feel dizzy, have chest pain, go numb or shiver uncontrollably.
• Not for children: lid closed when not in use, tub drained when nobody is watching it, never a child nearby without an adult.
