Currently, the term "cryotherapy" describes variegated treatments that are going with the use of very low temperature applied to the body surface. The first cryochamber in the world was set up by Yamauchi and his colleagues, in 1978. At present, there are at least several dozen cryochambers around the world. Nowadays, cryotherapy is widely practiced for the treatment of inflammatory conditions such as acute pain and swelling. Depending on the intended purpose, various clinical applications of cryotherapy differ in temperature conditions, exposure time, the humidity of the cold air, the rate of heat loss etc. Development of new methods of cryotherapy may be a subject of someone's medical high school capstone project. Generally, there are two main types of physical therapy based on lowering the body surface temperature. Local cryotherapy is applied to small body areas and represents ventilation with a mixture of cooled gases, which temperature ranges from – 34°C to -196°C. Whole-body cryotherapy involves the entire body, including the head and may be provided in the form of cryosauna or special cooling systems.
Cryotherapy uses various cryogens from cold water to carbon dioxide and liquid nitrogen. Cold water bath gives the most rapid effect, although can cause shock in a patient. Hereof, cryostimulation that employs dry cold such as vapors of nitrogen or carbon dioxide is considered as more convenient and safe. Certain thing, sceptics who know what is an article critique often point out in their critical work, that both liquid and dry cryogens are able to damage patients severely being use in the wrong way. Frankly speaking, liquid nitrogen used in therapy is not harmful at all due to its intensive evaporation during short contact with warm skin. Most important, one should elude the ingress of cryogens into the eyes because they might cause severe harm to the corneas. Usually, all dangerous substances are carefully kept in insulated containers and are safe from dramatic temperature changes.
Most often, cryotherapy is used for its analgesic impact; also, it helps reduce muscle tension, slow down metabolism and lower the effects of trauma. Currently, cryotherapy broadly proposes pain-soothing solutions for patients with locomotor disorders. The inability of effective movement influences people of all ages both psychologically and socially. Well, let us overlook diseases, which sociology paper topics sometimes mention as "most widely distributed and mind-troubling":
Certainly, whole-body cryostimulation strongly influences a variety of physiological and biochemical indicators in patient's body. Although, it is crucial to select an appropriate form and duration of cryostimulations as well as choose the right number of this procedure for each patient. Strangely enough, there are few biological research related to the effect of low temperatures on some other living things – for example, one can scarcely find a drosophila lab report format carried out with the use of cryogens.
Triggering defensive physiological mechanisms with such stressor as cold is going to be widely employed in sports medicine and physiotherapy. The widespread application of cryotherapy became a reason for its popularity; therefore one can easily meet it mentioned even in funny argumentative essay topics. To this very day, there exists no agreement or a single recommendation regarding the number of cryostimulations in a series. Generally, therapeutists use no more than ten cryostimulations per day. However, there are still not much data concerning the beneficial effect of a certain number of cryotherapeutic sessions as well as the specifics of adaptive changes in subjects. Due to this lack of knowledge, new enthusiasts and researchers are more than welcome to make their contribution to physiotherapeutic study.
