2. Those who reduce waist fat;

3, dysmenorrhea, limb cold, stomach cold;

4. Long-term standing or sedentary mental workers and manual workers;

5, the body is afraid of cold, postpartum pain, abdominal chills, low back pain, stomach cold and stomachache, lumbar muscle strain, lumbar disc herniation, hyperosteogeny, arthritis, physical fitness, daily protection and health care. 1. Wet the middle heating part of the protective device series with cloth first, and then fix the protective device directly on the skin.

2. Generally 15-30 minutes, you can feel the obvious thermal sensation. According to each person's physical condition, determine the length of wearing time. If the skin feels burning after use, it is normal, please take it off temporarily, and it will never damage the skin.

It can be used without water, but it takes a long time to heat. 1, this product can be washed and used repeatedly, avoiding the use of detergent (powder), and directly brushing with clean water to avoid long foam washing. Water immersion and washing are prohibited.

2. The following patients are prohibited from using this product:

Pregnant women, patients with malignant tumors, patients with varicose veins, and carriers of metal AIDS in the body (except dental metal objects).

The product has been tested: the far infrared emissivity of the directional part is above 85%, and the negative ion concentration index can reach about 1060. By absorbing external energy and natural heat energy of human body, it continuously releases far infrared rays with the wavelength of 8- 15um, which can penetrate deep into skin and subcutaneous tissue, generate vibration absorption with intracellular qi and blood, effectively relax vascular smooth muscle, dilate capillaries, improve microcirculation and strengthen intravascular activities. Activate biomolecules in human body, improve human metabolic function, and achieve the purpose of health care and rehabilitation.

3. Tourmaline heat-sensitive materials will only heat up when they meet water (such as sweat or steam). When the human body moves, there is sweat or moisture on the surface of the human skin, and the tourmaline heat-sensitive material heats up. People are at rest when they sleep, and there is little sweat or moisture on the surface of human skin, so they will not get hot. In addition, it can't be adjusted automatically and can't be worn in summer.

Proper use of self-heating protective devices such as waist pads and knee pads can improve the use effect, but it must be noted that some people are not suitable for using tourmaline products, such as people with pacemakers, people with insulin pumps, cancer and critically ill patients, patients with severe heart disease and patients with active tuberculosis.
