Heat therapy ( Thermotherapy ) & What are the clinical uses of heat ?
The heat therapy is also called thermotherapy , It is the use of the heat in therapy , such as for the pain relief and the health , It can be taken in the form of a hot cloth , hot water bottle , ultrasound , heating pad , the hydrocollator packs , the whirlpool baths , the cordless FIR heat therapy wraps and others .
The heat therapy can be beneficial to those with the arthritis and stiff muscles and the injuries to the deep tissue of the skin , The heat may be an effective self-care treatment for the conditions such as rheumatoid arthritis , The heat therapy is most commonly used for the rehabilitation purposes .
Therapeutic effects of the heat are increasing the extensibility of collagen tissues , decreasing the joint stiffness , reducing the pain , relieving the muscle spasms , reducing the inflammation , the edema .
The heat therapy aids in the post acute phase of healing and increasing the blood flow , increased blood flow to the affected area provides the proteins , the nutrients & oxygen for better healing .
The moist heat therapy is more effective at the warming tissues than the dry heat , because the water transfers the heat more quickly than the air , Moist heat can be used on the abscesses to help drain abscess faster .
Thermal Medicine or the manipulation of body or the tissue temperature for the treatment of the disease , It can be traced back to the earliest practice of medicine , The heat therapy is useful for the muscle spasms , myalgia , fibromyalgia , contracture & bursitis .
Ultrasounds are not absorbed in the homogenous muscle , The heat therapy using hyperthermia that has been used to treat the cancer in combination with ionizing radiation .
The heat therapy is contraindicated in case of the acute injury and bleeding disorders ( because of vasodilation ) , the tissues with a severe lack of sensitivity , scars and in the tissues with inadequate vascular supply .
Thermotherapy consists of application of heat or cold to change the cutaneous , the intra-articular and the core temperature of the soft tissue with the intention of improving the symptoms of certain conditions .
Infrared radiation is a convenient system to heat the parts of our body , The radiation can heat the area directly where the blood capillaries & the neuron terminals are .
The heat has to heat the external layer of the skin and the heat is transferred to the deeper layer by the conduction , Since the heat conduction needs a temperature gradient to proceed that can be safely used (around 42 °C) and it is a lower temperature where warming is needed .
Infrared is the part of the electromagnetic radiation spectrum comprised between 0.78 μm and 1 mm wavelength , IR radiation is more important than the visible radiation for heating our body because we absorb most of it , compared to a strong reflection of visible light .
The heat therapy can be used for the treatment of headaches and migraines , A lot of people who suffer from the chronic headaches also suffer from the tight muscles in their neck and upper back .
To achieve the heat therapy for the headaches , many use microwaveable pads that can often overheat , potentially leading to the injury and lose their heat after a few minutes .
Some new products use the heated water , running through the pads to maintain a constant temperature , allowing the headache sufferers to use hands-free heat therapy in the treatment of their headache pain .
