If a person's body is not strong enough, lacks exercise, usually sits and works all day, and his back muscles are weak and his spine is unstable, which affects the small joints, fascia and ligaments, low back pain and hyperosteogeny will occur.

The waist protector is made of tough natural leather, artificial leather or canvas, and some interlayers are longitudinally fixed with several elastic steel bars. After wearing it, the waist movement is limited, the stability is enhanced, and unintentional sprain can be prevented, so the symptoms of low back pain are obviously improved.

Extended data:

Most people need waist protection, not only in winter but also in summer. At this time, if the waist protector can't breathe and sweat, wearing it will become a torment.

Good waist protection can not only keep the waist warm, but also release far infrared and negative ions continuously. It also brings the thermoelectric stimulation effect of micro-current to human body. It can effectively improve blood circulation, relieve muscle fatigue, activate cells to promote metabolism, dredge meridians, dispel wind and dampness, relieve pain and dispel cold, and enhance the body's disease resistance. This product is safe, easy to use and durable.

Exert certain pressure on muscles to adjust the balance of exercise strength. Strengthen muscle strength and reduce swelling to some extent. During exercise, muscles are stimulated, metabolism is accelerated, and water in muscle cells is increased, resulting in the feeling of cell swelling. Proper pressure helps to make exercise easier and more powerful.

Double-layer or multi-layer materials have stronger heat insulation function than soft and comfortable waist protection. Athletes often wear less clothes in sports, but the waist radiates more heat, which is easy to catch cold, causing backache, cramps or stomach discomfort. Waist protection with thermal insulation can effectively maintain waist temperature, accelerate blood circulation, and prevent colds and some stomach discomfort.

Self-heating waist protection with magnets or activated carbon;

This waist protector has the function of spontaneous heat and magnetic therapy. The added magnet interacts with human body to emit heat, which continuously heats human body in cold season, so it is loved by many consumers. However, these activated carbon or magnets have their own life cycle, and the heating performance will be reduced after a long time.

In addition, activated carbon or self-heating is not adjusted according to the needs and comfort of the human body. Excessive heating will make people sweat, and sweat will be stored in the waist protection material, which will make the joint temperature drop rapidly and aggravate joint discomfort. Not suitable for summer and autumn.
