Side effects of cryotherapy are very mild, in fact in a vast majority of cases, effects never go beyond the benefits we seek with the treatment.
Liquid nitrogen in manages to carry out the cryotherapy treatment, either to reduce an inflammation, relieve pain, activate metabolism or any other purpose, once a session is finished our body does not usually suffer any variation.
If the treatment is not managed properly, either with non-homologue cabins or with home cryotherapy systems, the risks increase and side effects become worst, and blisters, bleeding and infections may appear.
In practically all treatments there is no side effect, since temperature is controlled, preventing burns and other harmful effects.
