Ice bathing for beginners: getting into cold water safely

Why so many people get into cold water in winter

Ice bathing is no longer a hobby for a handful of daredevils. On the shores of Swiss lakes and rivers, groups meet in winter to go into the water together, and more and more saunas offer direct access to a lake or river in addition to the plunge pool. Many describe the feeling afterwards as clear, awake and content — a short, intense moment that clears the head.

At the same time, cold water is not a playground. The body reacts strongly to cold, and getting the first few times wrong can put you in danger. This guide shows you how to start safely, step by step.

What happens in your body

The cold shock in the first seconds

As you go under, the blood vessels in your skin contract suddenly, your pulse and blood pressure rise, and almost everyone gasps for air reflexively. This so-called cold shock is strongest in the first minute. This is exactly where most accidents happen: anyone who breathes in uncontrollably, swallows water or panics quickly loses control.

The good news: the reflex eases noticeably after about a minute, and with a little practice you learn to keep breathing calmly.

Why short beats long

After the shock, your body cools down first in the hands and feet. Fingers stiffen and coordination drops. In really cold water this happens faster than many people think. For beginners, time in the water is therefore counted in minutes, not quarter hours. One to three minutes is plenty at the start.

Before your first time in the water

Never alone

The most important rule of all: never go into cold water alone. Someone with you on the shore or in the water can help if something goes wrong — and they often notice before you do that it is time to get out. Many towns have groups that meet regularly; beginners are usually welcome.

The right spot

To start, choose a spot with a gently sloping entry, firm ground and no current. Lakes are easier than rivers for beginners. In rivers in winter: only bathe close to the bank, don’t swim downstream and check the exit beforehand. Walking on ice or diving under an ice sheet is off limits.

The kit you actually need

• A warm hat — it stays on your head, even in the water
• Neoprene socks or water shoes against cold stones and sharp edges
• A large towel or a hooded bathrobe
• Warm clothes in layers that you can put on quickly
• A thermos of warm tea
• A mat so you don’t stand barefoot on the cold ground

Lay everything out so you don’t have to search after your dip. With cold fingers, every zip becomes a challenge.

Your first ice bath, step by step

1. Arrive and settle. Take a few minutes, breathe calmly and deeply. No sprinting to the water.
2. Go in slowly. Step by step, no jumping. Diving headfirst into cold water is dangerous.
3. Watch your breathing. When the water reaches your stomach, the breathing reflex kicks in. Breathe out long and deliberately, for example through slightly parted lips.
4. Keep it short. The first time, 30 seconds to a minute is enough. Over time you can extend to one to three minutes.
5. Get out in time. Get out while you still feel good. If you wait until it hurts, you have stayed in too long.
6. Warm up straight away. Dry off, put on warm clothes, move around, drink warm tea.

Warming up without mistakes

After the dip, your body keeps cooling for a while — many only start shivering properly a few minutes after getting out. That is normal. Get dressed quickly and move gently, for example on a walk. Many find a hot shower straight afterwards unpleasant because it puts extra strain on the circulation. Better to warm up slowly and from the inside.

Ice bathing with a sauna: the easier way in

The most pleasant way to start is where there is a sauna. You warm up before the cold dip, cool off briefly and then go back into the heat. Many saunas in Switzerland sit right on a lake or river or have an ice bath.

• In the section Saunas with ice baths you will find venues with a particularly cold plunge pool or direct access to the water.
• Under Ice bathing with a sauna you can see bathing spots with a sauna within walking distance.

A typical routine: ten minutes in the sauna, briefly into the cold water, then rest. Read more in the article on the classic three-round sauna ritual.

Where to go ice bathing in Switzerland

The Ice bathing overview shows bathing spots on lakes and rivers that are accessible in winter, plus saunas with ice baths. Lake shores with gentle access are best for beginners. Under Ice bathing in lakes and Ice bathing in rivers, the spots are sorted by body of water, each with notes on access and safety.

Where available, we show the current water temperature live, measured by the stations of the Federal Office for the Environment and the City of Zurich. That way you know how cold it will be before you set off.

Frequently asked questions

How cold does the water have to be for an ice bath?

There is no fixed limit. In everyday usage, single-digit temperatures usually count as ice bathing and anything above that as winter swimming. For your body, water below 15 degrees already makes a big difference — that is more than enough to start with.

How often should I go ice bathing?

Listen to your body. Many go once or twice a week during the cold season. If you start in autumn and carry on as temperatures drop, you get used to the cold gradually.

Can I drink alcohol after an ice bath?

Better not. Alcohol widens the blood vessels and creates a false sense of warmth while your body keeps cooling down. Warm tea is the better choice.

What do I do if I feel dizzy?

Get out of the water immediately, sit down, put on warm clothes and tell the person with you. If the symptoms persist, call the emergency number 144.

Conclusion

Ice bathing is intense, but it is not a test of courage. If you prepare well, never go alone and only stay in the water briefly, you can get to know the cold step by step. Start small, ideally with a sauna nearby — and enjoy the moment when you stand on the shore, wrapped up warm.
