Frigid weather is the time when the hot water bottle comes into play, but using the hot water bottle as a simple heating device is a bit overkill. In fact, it also has many unexpected health care uses.

1. Promote wound healing

    I poured warm water into the hot water bag and put it on my hand. At first, I just felt warm and comfortable. After applying it for a few days, the wound was completely healed.

    The reason is that heat can stimulate tissue regeneration, relieve pain and strengthen tissue nutrition. When heat acts on wounds on the body surface, a large number of serous exudates increase, which can help remove pathological products. Heat can dilate blood vessels and enhance vascular permeability; which is conducive to the discharge of tissue metabolites and the absorption of nutrients, inhibits the development of inflammation and promotes its healing.

2. Pain relief

    For knee joint pain, put a hot water bottle on the knee and the pain will be relieved quickly. In fact, hot compress can not only relieve joint pain, but also significantly relieve pain for lumbago, sciatica, dysmenorrhea (all of which are cold syndromes). Placing a hot water bottle on the local pain area for 20 minutes each time, 1-2 times a day. Subcutaneous hematoma caused by contusion, 24 hours after injury, apply hot compress with hot water bag to promote the absorption of subcutaneous congestion.

3. Apply back to relieve cough

    In winter, if you have a cold and cough, fill a hot water bottle with hot water, wrap it with a thin towel and apply it on the back to drive off the cold. Which can quickly stop the cough. Applying hot compress to the back can dilate blood vessels and accelerate blood circulation in the upper respiratory tract, trachea, lung, etc., to enhance metabolism and phagocytic ability of white blood cells, and to relieve cough. This method is especially effective for coughs that appear in the early stages of colds.

4. Hypnosis

    Put the hot water bottle on the back of the neck while sleeping, it will feel mild and comfortable. The hands will get warm first, and then the feet will also feel warm; which can play a hypnotic effect. This method is also suitable for the treatment of cervical spondylosis and frozen shoulder.

    In addition, at the beginning of mastitis, put a hot water bottle on the local pain area, twice a day. For 20 minutes each time, it can promote blood circulation and remove blood stasis; if the intravenous infusion is not smooth, apply a hot compress to the hot water bottle to make it smooth. Long-term intramuscular injection of penicillin and Injections and intramuscular injections are prone to induration and pain, redness, and swelling. Applying a hot water bag to the affected area can promote the absorption of the medicinal liquid and prevent or eliminate induration.

    The protruding part on the hot water belt can play a smaller contact area than the human body, so as to reduce the heat release speed of the hot water bag.
