Open swimming is a natural antidote to stress and mood. Research has also shown that certain pain conditions and swelling can be combated with cold exposure with lifeguard certification near me.
Open swimmers often describe the euphoric feeling that follows them after swimming in the cold. The feeling may be so addictive that open swimming becomes a long-term hobby.
One explanation is that open swimming works as an effective stress killer. A research report published at the beginning of 2019 by the University of Oulu states that open swimming constricts peripheral blood circulation and thus temporarily raises blood pressure. Noradrenaline secretion increases, which explains the feeling of victory brought by open swimming and the feeling of being "really alive".
As open swimming becomes more regular, the secretion of noradrenaline decreases as the body gets used to cold exposure. With this, the body's cold resistance and pain tolerance also increase.
In the study, regular open swimming increased the amount of dopamine and endorphin in the swimmers' blood, which is connected to the reduction of depression and stress. In other words, the stress tolerance of open swimmers improves.
The health effects were only observed when open swimming was regular and the person swam several times a week.
" Regular and sufficiently frequent cold exposure is key when you want to improve cold tolerance and possible health benefits.
And can a cold shower and walking around in the snow produce the same benefits?
- Cold showers and especially circling in snow haven't been studied as much as open swimming. In all cold exposures, changes occur in the body, but the effects on the changes can vary, says Sirkka Rissanen , specialist researcher at the Institute of Occupational Health .
- It can be said that regular and sufficiently frequent cold exposure is key when you want to improve cold tolerance and possible health benefits. Skiing in the snow is perhaps less often done regularly, and its disadvantage can be the structure of the snow - in hard snow, the skin can break with American Lifeguard Association Va.
Cold can help, for example, with joint pain
According to American lifeguard , a cold shower can harden the body to the cold.
- There is also a so-called mist shower available on the market, where the cold water comes as a fine mist and the cooling function is based on the evaporation of water from the skin.
The cooling of the tissues and cortisol together prevent the sensation of pain. For example, many people with joint pain and rheumatism get help with regular open swimming.
In 2016, Dissertation research on extreme cold therapy, published in 2016, showed that exercise or going through joint range of motion in a patient with severe rheumatoid arthritis, which was started immediately after the cold treatment, went more painlessly.
In Studies conducted at the Rheumatism Foundation's hospital, a comparison group consisting of open swimmers was involved. Extreme cold therapy and open swimming produced similar effects. A 20-second open swim corresponds to about two minutes in cold therapy.
