Far-infrared textile health care products, if the inherent magnetic field is too weak, will not play a therapeutic role; If the effect is too strong, it will cause harm to the body, especially to the cardiovascular and cerebrovascular diseases and the reproductive system. For heart patients with pacemakers, wearing far infrared underwear is more likely to have adverse consequences.

When using far-infrared physiotherapy in hospital physiotherapy department, there are strict requirements on the treatment object, treatment time and distance. Generally, each treatment time is 15 ~ 30 minutes, and the radiator is 30 ~ 60 cm away from the skin surface. Patients with arterial obstructive disease and bleeding tendency, patients suspected of malignant tumor or fresh scar tissue at the heating site, and patients with cardiovascular insufficiency are prohibited.

Extended data:

Far infrared rays have strong penetrating power and radiation power, and have obvious temperature control effect and vibration effect, which are easily absorbed by objects and converted into internal energy of objects. After being absorbed by human body, far infrared rays can make water molecules in the body vibrate, activate water molecules and enhance their intermolecular binding force, thus activating biological macromolecules such as protein and making biological cells at the highest vibration level.

Due to the vibration of biological cells, far-infrared heat energy can be transmitted to the deeper layer of human skin, and the temperature below the deep layer rises, and the generated warmth is emitted from the inside out. The intensity of this effect can dilate capillaries, promote blood circulation, strengthen metabolism among tissues, increase the regeneration ability of tissues, improve the immune ability of the body, and adjust the abnormal excitement of the spirit, thus playing a role in medical care.

Far infrared heating technology has obvious advantages. This technology has been widely used in the process of heating, melting, drying, molding, consumption and curing of many products or materials, such as coatings, plastics, food, medicine, wood, leather, textiles, tea and tobacco. With the increasing variety and quantity of far-infrared products, its application field is also expanding, and far-infrared heating technology has attracted people's attention and been widely used.
