Heat and Cryotherapy in Hyderabad
Heat Therapy or Thermotherapy is the application of any substance to the body that increases tissue temperature. This results in improved blood flow, tissue metabolism and connective tissue extensibility. Increased blood flow facilitates tissue healing by supplying protein, nutrients and oxygen at the site of injury.
This increase in metabolism helps the healing process by increasing both the catabolic and anabolic reactions needed to degrade and remove the metabolic by-products of tissue damage.
Skin warming has also been shown to activate the thalamus and the cerebral cortex, and some of the pain relief provided by topical heat therapy may be mediated directly by the brain.
Cold analgesia or Cryotherapy is the local or general use of low temperatures in medical therapy, or the removal of heat from a body part to relieve pain. The cold causes vasoconstriction, which results in decreased tissue blood flow, and reduces tissue metabolism, oxygen utilization, inflammation and muscle spasm. Common methods include topical cooling gels and freeze sprays. Other forms of cryotherapy include ice packs, ice massages and cold whirlpools.
Cryotherapy induces effects locally at the site of application and in the spinal cord. Topical cold treatment decreases the temperature of the skin and the underlying tissues to a depth of about 2–4cm, decreasing the activation threshold of pain receptors and the conduction velocity of pain nerve signals. This results in a local anaesthetic effect and a reduction in pain.
