There, taking a dip in icy water is part of the cultural legacy handed down from older generations to the younger Gen Z.

The obvious reason for the historical tradition of swimming in cold water is that in countries with the climate of Sweden or Finland, one can hardly find a natural water source with a relatively warm water, even in the summer.

It is claimed that this hobby brings great health benefits, such as lifting up the mood and boosting the metabolism and immune system. Thus, dipping in cold water can be considered as a great tonic for the body and mind

This is confirmed by medical experts‘ opinion. According to the British Heart Foundation, swimming in cold water can improve blood pressure and blood fat levels when practiced regularly by people in good general health.

The heart speeds up its rate when a person moves in the water. And the colder it is, the harder it should work.

Just getting into icy water can generate "cold shock" causing a rapid heart rate, higher blood pressure and shortness of breath.

Therefore, if a person has a heart condition, there are risks that he/she should consider and consult his/her general practitioner before practicing swimming in cold water. It is advisable for beginners to acclimatize gradually to lower water temperatures, so that the body can get used to over time.

Apart from its health benefits, cold water swimming can also be a fantastic social hobby as there are many clubs and support groups around the world to practice it.
