The heat spreads from the thermal mat to the person's body, producing a temperature increase, which causes a relaxing and therapeutic effect. It consists of the application of heat in certain areas during short sessions of time.


In order for heat to pass from one body to another, it is necessary to use the following mechanisms: conduction, convention and radiation. Some of the methods are:
- Solid conductive media
- Hot sand
- Hot wraps
- Thermophores
- Chemical bags
- Electric pads or mats
- Semi-solid and liquid conductive media
- Wet compresses.
- Kerosene and kerosene wax.
- Mud therapy.
- Hot hydrotherapy.
- Convective media
- Dry air and humid air.
- Dry air and humid air.
