Winter swimming, which means taking short baths in cold water. People who practice winter swimming have peculiar names – in Poland, they are called "morses," in Finland "seals," and in the USA "polar bears." Winter swimming has a long tradition. The first mentions of cold baths date back to antiquity. Winter swimming can generally be defined as immersion or a short bath in cold water. Water with a temperature below 5°C is considered as such. Winter swimming can be practiced in a lake, river, sea, or any other body of water from autumn to spring. It is done individually, although group winter swimming is quite popular. Most enthusiasts of this form of activity come from Nordic countries and Eastern Europe.

Preparation for winter swimming

The first and most important thing we should do when starting our adventure with winter swimming is to visit a doctor to rule out any contraindications to this type of activity. Then we should start training in the summer, swimming in rivers or lakes, gradually getting our body used to lower temperatures. Another very important step is to regularly take cold showers. First, take a bath at a comfortable temperature, then turn the coldest water on and pour it over the body, from the feet towards the heart. It is important to maintain steady breathing and stay calm. Such a shower should last about 3 minutes at the beginning, but over time we can extend it.

Equipment and preparation for winter swimming

Cold water baths are taken in appropriate clothing. A winter swimmer wears a swimsuit and protects the parts of the body most sensitive to low temperatures – gloves on the hands, and a swimming cap and hat on the head. Special shoes for winter swimming in water are required. The bath is preceded by at least a 15-minute warm-up. Entry into the water should be decisive, and submersion gradual. Beginners should stay in the cold water for several dozen seconds. Experienced winter swimmers can allow themselves a bath lasting several minutes, on average 3-5 minutes. When going deeper underwater, remember to tense muscles and hold your breath.

Is ice swimming safe?

If we follow the rules, ice bathing is a safe form of physical activity. Above all, we must have knowledge and be aware of the risks we are taking. Staying too long in icy water can lead to hypothermia. This is a condition in which our body temperature drops below 35 degrees Celsius. The first symptom is muscle shivering, which can be followed by loss of consciousness, which in turn can result in drowning. Therefore, ice bathing alone is not recommended.

Another danger that can occur is thermal shock. At the moment we enter icy water, the muscles supporting breathing contract. This can lead to hyperventilation, which we will be unable to control, and as a result to choking and death. Ice bathing is very dangerous for people with heart failure because cold water causes centralization of circulation, which in turn results in excessive strain on the heart.
