Swimming in the ice

In summer you dream of a refreshing dive, but there are those who look for it even in winter. Indeed more than refreshing... we should say “freezing.” Ice swimmers, which differs from the “simple” winter swimming by the water temperature in which it is practiced: it must not be higher than 5 degrees centigrade. Therefore, the races of this peculiar sport are held in ice-covered basins, with outside temperatures below zero.

Lea Kusano, from Bern, who is part of the International Ice Swimming Association, tells us how this passion came about. And don’t think it’s just for special athletes; it can be commonly practiced and also bring benefits to your immune system.

When did you discover ice swimming?

“I started swimming in winter about nine years ago and intensified this hobby over the years. My swimming activities became more and more regular and the more I trained, the more I was able to swim in colder water and increase my stay, until I got into ice swimming.”

 

Why did you choose to practice it?

“At the time, I had read a report on silence that had been done with an ice freediver. I was fascinated by the idea of being in total control and total relaxation at the same time and the idea of silence surrounding this moment. I knew immediately that I had to try it. This feeling remains even after all these years, and although I long for summer every year, I have moments when I wish I could enter into this moment of total clarity, concentration, silence and a kind of positive solitude. I have been practising apnea for a few months now and sooner or later I will intensify this activity. I think that with a little exercise I will have the same sensations.” 

 

Is it just a challenge to the cold or is it also a healthy sport?

“Being in the cold has many positive effects on the body and mind, such as a better immune response. In addition, certain hormones are activated, such as adrenaline, endorphins and corticoids, which are anti-inflammatory. Personally, my body and mind are immediately calmed by the cold, so it is a great stress relief with an immediate impact.”

 

Contraindications?

“I believe that in principle everyone is able to swim in cold water, but one must be careful. Those with severe asthma, heart problems or cardiovascular risks should contact their doctor first. Also, never go alone and, very importantly, do not do it in open water the first few times, easily the cold shock will make you hyperventilate. As for the challenge, for me it is not about the challenge. It’s more about immersing yourself in the sensations I described above.”

 

Does it require special clothing or equipment?

“Yes and no. Swimming itself can be done in a normal swimming costume. I often use neoprene gloves and shoes to protect myself, you can order them in many online shops. But it is important to be well prepared for after swimming, to have a hat and gloves and very warm clothes. It is important to warm up quickly.”

 

When was your first competition and what did you experience?

“It was in 2023, at the IISA World Championships in Samoëns and it was absolutely fantastic to meet all these people from all over the world. The swimming itself was very different from what I am used to experiencing. There is no time to adapt to the cold, you just have to get in and swim immediately. The most surprising experience was that I felt nothing as I entered the icy water. No sensational cold, no interruption of my breathing rhythm: the power of adrenaline!”

 

Where is ice swimming practised in Switzerland? And specifically in Italian-speaking Switzerland?

“Wherever there is water. I think it is very nice to swim in the valleys of Ticino when there are no tourists. Personally, I have swum several times in the lake around Lugano. There are several swimming groups in all the major resorts around Lake Zurich, Lake Zug, the Rhine and Aare rivers and Lake Geneva. Ice swimming and winter swimming swimmers are very open people, so contact them when you see them live or on Instagram. And of course you can always get in touch with the International Ice Swimming Association Switzerland.”

 

Will there be Swiss athletes at the upcoming World Championships in Molveno? Who in general are the best athletes in the sport? 

“Yes, and more than one. As far as the rankings are concerned, there are two types. The overall winners and the age-group winners. Age groups go up to over 100 years old. At the European Championships my age group was quite large, and for my abilities there was no chance of a medal, I just have to wait until I get a bit older.”

 

Some advice for those who want to approach this sport, how to start? What are the mistakes to avoid?

“The first step is obviously to adapt to the cold water. My advice is not to stop swimming at the end of the summer. Continue and adapt slowly as the temperatures drop. And remember to have warm clothes after your swim.  If you really enjoy swimming and not just taking a dip - which by the way is great and also cool - the biggest mistake is not exercising. Go swimming in the pool and do weight training.”

 

Three reasons for ice swimming?

“The reasons for practicing ice swimming lie only in yourself. If you find them, do it.”
