Hydrotherapy can promote human metabolism
The effect of water therapy on the system of human body is the result of temperature, mechanical and chemical stimulation.
The skin is rich in blood vessels and nerve endings. Thus the expansion or contraction of the skin blood vessels can have a great impact on the distribution of blood, such as skin capillary expansion can accommodate the whole body of blood 1/3. The skin has a lot of spinal nerves and vegetative nerve endings, the stimulation of peripheral can affect the functions of central nervous system and visceral organs, and achieve the aim of anti-inflammatory, antipyretic, analgesia, sedation, hypnosis, excitation, sweating, diuresis and reducing muscle ligament tension, relieving spasm, promoting metabolism and improving the regulation function of nervous systems.
Whole body cold bath, initial capillary contraction, heart beats accelerate, blood pressure rises, but soon again appears blood vessel dilate, cardiac pacing slows down, blood pressure reduces, immediately relieved the burden of heart. Therefore, it is believed that the cold can improve the myocardial ability, slow the cardiac pacing and improve the myocardial nutrition.
