Your First Cold Plunge: What to Expect (and How to Not Hate It)

1. Before you arrive

What to bring, and what not to bother with

Bring a swimsuit. That’s genuinely it. Towels, water, electrolytes and tea are all provided, so you don’t need a bag full of things.

Eat something a couple of hours beforehand rather than right before, and don’t arrive dehydrated — you’ll sweat more in the sauna than you expect. Arrive about five minutes early, which is enough to change and get your bearings without standing around.

Your session is a personalised, semi-private appointment time. You are not sharing the space with a queue of strangers, and you don’t need to hurry.

2. Start with the heat

Ten to fifteen minutes, no heroics

You begin in the cedar sauna at 198°F. That number sounds alarming written down; in practice it’s a dry heat, so it’s far more tolerable than the same figure would be in a steam room.

Sit on a lower bench if you’re unsure — heat stratifies, so the bottom bench is meaningfully cooler than the top. Stay ten to fifteen minutes, until you’re properly sweating and your shoulders have dropped. There is no benefit to gritting it out longer, and going in overheated makes the plunge harder, not easier.

3. The first thirty seconds of cold

The gasp is normal — and it passes

This is the part everyone is asking about. You step into the 50°F plunge and your body does something involuntary: a sharp inhale, a tightening chest, an immediate and quite loud opinion that this was a mistake.

That reaction is called the cold shock response, it happens to everyone including people who have done this for years, and it fades within roughly thirty seconds. Knowing that in advance is most of the battle.

The one thing that helps more than anything else: slow your exhale. Get in gradually rather than dropping, keep your shoulders down, and make your out-breath longer than your in-breath. When your breathing settles, everything else settles with it. If you fight it and hold your breath, the thirty seconds feel like three minutes.

4. How long to stay in

Shorter than you think

One to three minutes is a real, complete plunge. First time, aim for one. If your breathing is calm and you want to stay longer, stay longer — but there is no prize for it, and the benefits do not scale with suffering.

Get out if you start shivering hard, if your breathing won’t settle, or if you simply want to. Then go back to the sauna and warm up properly, and do the whole loop again. Two or three rotations over an hour is a normal session.

There’s a second plunge at 40°F when you want a harder version. Ignore it entirely on your first visit. It will still be there in a month.

5. The mistakes worth skipping

Four things first-timers do

Holding your breath. The most common one, and the one that makes it genuinely unpleasant. Breathe out slowly instead.

Jumping in fast to get it over with. It doesn’t shorten the shock, it sharpens it. Step in steadily.

Trying to beat someone. Whoever you came with is not your competition, and the person who stays in longest is not getting more out of it.

Rushing out the door afterwards. Give it ten minutes. The last part is the best part.
