Hot compress bag is one of the methods of hyperthermia. Hot compress bag, hot towel, wax therapy and infrared ray all belong to shallow hyperthermia. Hyperthermia is a kind of physical therapy, which uses heat source to raise the temperature of the affected part, dilate blood vessels and accelerate metabolism. Improving blood circulation can achieve the effect of relieving chronic inflammation, and improving metabolic rate can accelerate recovery. In addition, based on warming, nerves can be warmed to achieve the effect of relieving pain (refer to the "pain gate theory" of gray matter around aqueduct in midbrain) and relieve muscle spasm. Low back pain in pregnant women is very common. However, due to the potential safety problems of drugs, electrotherapy, magnetic therapy and deep ultrasound, the most acceptable scheme is still hyperthermia, among which hot compress bag is the most common.

[1] Contraindications of hot compress bag Although hyperthermia can effectively treat chronic waist and neck pain, degenerative arthritis, muscle fatigue or spasm, patients with acute inflammation (swelling and pain in the site), dermatitis, wound in the affected area and severe diabetes have lost the ability to distinguish between cold and heat, and can't read the instructions (such as severe Alzheimer's disease) or those with mobility difficulties (such as paralysis). The types of hot compress bags can be classified according to their filling materials. Hot compress bags are usually made of rubber, and they are filled with hot water when used. Because of its low price, this hot water bottle is the most common heat source. Recently, there are many lovely hot water bottles on the market, which are very popular. Unfortunately, burns caused by knocking over or leaking hot water are also common, so it is not recommended for the elderly or children to use it alone without a strong adult. Gel: The contents of this hot compress bag are usually propylene glycol. Because it has no contact toxicity and will not harden at low temperature, it will also be used in cold therapy. Dangers include burns caused by leaks. It has been reported in the past that users' hot compress bags burst when heated.

Herbal-filled hot compress bags are high-end products, so they are not often sold in retail stores. The filling material is usually plant seeds or herbs. The principle is that there are many tiny holes on the surface of this plant material, and the indoor environment will regain moisture slightly, so the effect of wet fumigation and hot compress can be achieved by heating water in a microwave oven. Some products also use vanilla to make it have a faint fragrance. There are also products using traditional Chinese medicine, but the effect of hot moxibustion has not yet been determined. If the product is kept in the refrigerator, it can also be used in cold therapy. Refer to hot compress health care tips for the elderly. Hongkong, China * * [2011-kloc-0/1-26]. Hot skin?
