During the session
We will speak about effects consequent to this type of exposure (extreme cold) lasting only 3 minutes and not about effects caused by long exposure.
The average temperature of the skin is around 30°C. During the 3 minutes of a session at -80°C, it decreases quickly in a significant way to reach 15°C. Skin is the first organ in contact and thus stimulated by the cold.
In consequence :
the metabolism uses different mechanisms (nervous, vascular, endocrine) to conserve the core body temperature of 37°C and thus protect the vital organs
Effects due to the Thermal Shock
Suppression of the nerve fibres
There are several types of sub-dermal nerve fibres. Those which interest us are "A delta fibres" and “C fibres"
“A delta fibres“ pass on mechanical and thermal information. They are responsible for the first sensations caused by a specific painful phenomenon: " Ouch ! That pricks !"
“C fibres” pass on pain, such as a burn. The pain is not felt immediately, and the feeling is more diffuse and longer lasting
Vasoconstriction of small sub-dermal blood vessels and shive
The exchanges between the nuclei and the extremities are limited, because blood is no longer circulating as freely in the peripheries (skin, hands, feet, ears) which is directly in contact with the cold
The blood volume is redistributed towards the central organs and the muscles
The shivering is caused by muscular contractions without any movement, all the energy that is produced is translated into heat
Thanks to the increased muscular perfusion: cells have a better supply in oxygen and other elements necessary for their contraction. The produced heat (the hotter blood flowing out of the muscles) can be driven towards the vital organs
Cryotherapy in the form of cure (several sessions) allows a better vascularization of the skeletal muscles
A decrease of the production of muscular proteins and micro-lesions (action anti-inflammatory)
Unaccustomed and vigorous exercise causes damage in the skeletal muscular tissue
Some damage has been observed : micro lesions of the muscular fibre, inflammation of connective tissues, a prolonged reduction in muscular strength and in the amplitude of movement, and an increase in the appearance of muscular proteins in the blood (Prostaglandins and Creatine Kinases) those affect the ends of the afferent nerves in the muscles and increases the perception of the pain
Sympathetic stimulation and neuro-endocrine reactions
The sympathetic nervous system transmits the information from the skin to the brain
Once stimulated, this will enable the secretion of noradrenaline: "the wellbeing hormone». The increase the plasma level infers a general wellbeing, decreases the depressive syndrome and sleeping disorders
Decrease in inflammatory reactions
Recommanded for chronic pathologies such as multiple sclerosis, polyarthritis, fibromyalgia....
Or skin problems, such as the eczema
Increase in the basic consumption of calories
During the shivering, the metabolism burns calories stocked in the fat cells largely in order to produce some heat and stay at a good temperature
With regular sessions and as a supplement to a healthy lifestyle it can help you lose weight
Smoothing of the skin
The cold tightens the cutaneous pores, the skin is clearer and the ageing process is slowed down
Increase of the blood oxygenation and the elimination of waste (lactate)
