Hot therapy , also called thermotherapy , is the use of heat in therapies, such as for relief of pain and health. It can take the form of hot cloth, hot water bottle, ultrasound, heating pad, hydrocollator package, whirlpool bath, hot packing FIR therapy without cable, and others. This can be beneficial for those suffering from arthritis and stiff muscles and injuries to deep skin tissue. Heat may be an effective self-care treatment for conditions such as rheumatoid arthritis.
Hot therapy is most often used for rehabilitation purposes. Therapeutic effects of heat include increasing the expansion of collagen tissue; reduce joint stiffness; reduce pain; eliminating muscle spasms; reducing inflammation, edema, and relief in the acute post-healing phase; and increase blood flow. Increased blood flow to the affected area provides protein, nutrients, and oxygen for better healing.

Moist heat therapy is believed to be more effective at heating tissue than dry heat, because water transfers heat faster than air. Clinical studies do not support popular belief that damp heat is more effective than dry heat. The humid heat produces a perception that the network is heated deeper. In fact, recent research has shown that vasodilation, the expansion of blood capillaries (blood vessels) to allow for more blood flow, is enhanced by dry thermal therapy. Blood capillary expansion is the main goal of therapeutic therapy. Hot therapy increases the effect on muscles, joints, and soft tissues. Heat is usually applied by placing a warmer in the relevant body part.
The new generation of therapeutic devices combines carbon fiber heater with lithium battery that can be recharged without cables and built into certain body wraps ( i , shoulder wrap or back wrap) for targeted hot therapy. Such devices can be used as an alternative to electrically or electrically heated pads, but have not been shown to improve clinical benefits. All devices mainly provide heat to promote vasodilation.
- Infrared radiation
Infrared radiation is a convenient system for heating parts of our body. It has the advantage over direct contact in radiation that can heat directly the area where the blood capillaries and terminal neurons are located. When heat comes from a direct source of contact, it has to heat the outer layer of skin, and heat is transferred to a deeper layer by conduction. Because heat conduction requires a temperature gradient to continue, and there is a maximum temperature that can be safely used (about 42 ° C), this means lower temperatures where heating is required.
Infrared ( IR for short) is part of the electromagnetic radiation spectrum that is between 0.78? M and 1 mm wavelength. Usually divided into three segments:
IR-A , from 0.78 to 1.4? m.
IR-B , from 1.4 to 3? m.
IR-C , from 3? m up to 1 mm.
IR radiation is more useful than visible radiation to heat our bodies, because we absorb most of it, compared to the strong reflections of visible light. Penetration of the depth of infrared radiation in our skin depends on the wavelength. IR-A is the most penetrating, and reaches several millimeters, IR-B penetrates into the dermis (about 1 mm), and IR-C is mostly absorbed in the outer layer of the epidermis (stratum corneum). For this reason, infrared lights used for therapeutic purposes produce IR-A radiation.

Mechanism of action, and indication
The heat creates higher tissue temperatures, which results in vasodilation that increases the supply of oxygen and nutrients and the elimination of carbon dioxide and metabolic waste.
Hot therapy is useful for muscle spasms, myalgia, fibromyalgia, contractures, bursitis.
Moist heat can be used in the abscess to help drain the abscess more quickly. A study from 2005 showed hot therapy to be effective in treating leishmaniasis, a tropical skin parasitic infection.
Hot therapy is also sometimes used in the treatment of cancer to increase the effects of chemotherapy or radiotherapy, but it is not enough to kill cancer cells themselves.
Hot therapy is contraindicated in cases of acute injury and bleeding disorders (due to vasodilation), tissues with lack of sensitivity, scarring and tissue with inadequate vascular supply (due to increased metabolic rate and demand for tissue with poor blood supply may fail to meet resulting ischemia ).
The use of heat therapy for deep tissues can be treated with shortwave, microwaves, and ultrasonic waves. This results in high temperatures that penetrate deeper. Shortwave generates 27MHz current, microwaves using 915 and 2456 MHz, and ultrasound is a 1MHz acoustic vibration. The way ultrasonic waves work is that they selectively superimpose incoming waves and increase energy for absorption, and a significant portion of the longitudinal compression is converted into shear waves. When they are rapidly absorbed, the interface between soft tissue and bone is selectively heated.
For headache
Hot therapy can be used for the treatment of headaches and migraines. Many people who suffer from chronic headaches also suffer from tight muscles in the neck and upper back. The constant application of heat to the upper back/back can help release tension associated with headaches. To achieve heat therapy for headaches, many use microwave pads that are often overheated, potentially injurious, and heat loss after a few minutes. Some new products use hot water, run through the pads, to maintain a constant temperature, allowing headaches patients to use hands-free heat therapy in the treatment of their headaches.
Therapeutic Benefits
Therapeutic enhances the expansion of collagen tissue. Using heat, it can relieve stiffness in the joints in different cases. Shortwave applications and microwaves can reduce muscle spasms, and selective heating with microwaves can accelerate hematoma absorption. This will, in turn, allow stiff muscles to stretch. Ultrasound is not absorbed significantly in homogeneous muscles. Hot therapy using hyperthermia has been used to treat cancer in combination with ionizing radiation.
