Is the hot water bottle good for your health?
Winter is the time for hot water bottles to show their talents, but if they are only used as simple heating equipment, they are a bit overqualified. In fact, it has many unexpected medical and health care uses.
1, promoting wound healing: Aunt Zhang accidentally cut her finger while cutting vegetables three days ago. The wound hasn't healed because of the cold weather. She put warm water in a hot water bottle and put it on her hand for hot compress. At first, she only felt warm and comfortable. After several days of continuous application, the wound healed completely. The reason is that heating can stimulate tissue regeneration, relieve pain and strengthen tissue nutrition. When warm is applied to body surface wounds, a large number of serous exudates increase, which is helpful to remove pathological products. Heat can dilate blood vessels, enhance blood vessel permeability, facilitate excretion of tissue metabolites and absorption of nutrients, inhibit the development of inflammation and promote its healing. 2. Relieve the pain: Grandma Wang, 65 years old, suffered from knee pain due to the sudden drop in temperature a few days ago. When she was confused about the pain, she accidentally put a thermos bottle on her knee, and the pain quickly eased. In fact, hot compress can not only relieve joint pain, but also have obvious analgesic effect on low back pain, sciatica and dysmenorrhea (all of which belong to cold syndrome) by placing a hot water bottle in the local pain area for 20 minutes every time, 1 ~ 2 times a day; For subcutaneous hematoma caused by sprain and contusion, hot compress with hot water bottle can promote the absorption of subcutaneous congestion 24 hours after injury.
3, apply back to relieve cough: Mr. Ma coughs when it is slightly cold in winter. After that, under the guidance of a doctor, fill the hot water bottle with hot water, wrap it with a thin towel and apply it on the back to drive away the cold, which can quickly relieve cough. Hot compress on the back can dilate the blood vessels in the upper respiratory tract, trachea, lungs and other parts, accelerate blood circulation, enhance the metabolism and phagocytosis of white blood cells, and have a cough relieving effect. This method is especially effective for coughing at the beginning of a cold. 4, hypnosis: I can't sleep, the doctor told him that when sleeping, put the hot water bottle on the back of the neck, you will feel soft and comfortable, first the hands are hot, and slowly the feet feel warm, which can play a hypnotic role. This method is also suitable for treating cervical spondylosis and scapulohumeral periarthritis. 5. In addition, in the early stage of mastitis, put the hot water bottle on the local pain twice a day for 20 minutes, which can promote blood circulation and remove blood stasis; If the intravenous infusion is not smooth, you can use a hot water bag to make it smooth; Long-term intramuscular injection of penicillin and injection into the buttocks are prone to local hardening, pain and redness. Hot compress with hot water bottle can promote the absorption of liquid medicine and prevent or eliminate induration.
Use electric hot water bottle to guard against three major injuries in cryogenic burns.
If the electric hot water bottle is used improperly, it will easily lead to cryogenic burns. Skin exposed to low-temperature heat for a long time will gradually develop into deep dermis and subcutaneous tissue burns. The wound pain of low-temperature burn is not obvious, but the skin appears redness, blisters, peeling or whitening, and the area is not large. However, serious wounds can even lead to deep tissue necrosis. If it is not handled properly, it will fester seriously and will not heal for a long time.
In order to avoid this kind of injury, the heating temperature can be properly controlled when using the electric hot water bottle. After heating, an envelope or towel can be wrapped outside the electric hot water bottle, so that the electric hot water bottle does not directly contact the user's skin.
dermatitis
If the electric hot water bottle is used for too long, it is easy to induce dermatitis. This is because long-term use of electric hot water bottles will cause excessive water loss in the skin, which will become dry and itchy, leading to skin allergies and dermatitis. Especially the elderly or people with dry skin should pay special attention. Therefore, the use of electric hot water bottles should also pay attention to hydration.
explosion
Since the explosion of electric hot water bottles was reported by the media, many people have a lingering fear about it, and it is inevitable that they will be a little scared when using electric hot water bottles. Electric hot water bottles do have certain explosion hazards, but as long as they are used properly, it can be avoided by giving priority to reputable and large-scale merchants when purchasing. At the same time, remember to buy an electric hot water bottle with a heating wire, and never buy an electrode hot water bottle. The electrolyte solution in the electrode thermos bottle is in a charged working state, and once it leaks, it is in danger of electric shock; In addition, because the electrode is in direct contact with the liquid, the efficiency of converting electric energy into heat energy is high, and there is no temperature control device, so the hot water bottle expands greatly after being electrified and is prone to explosion. In contrast, the heating element of the electric heating wire hot water bottle is not in direct contact with the liquid, and the coil is separated from the liquid through the insulator, thus ensuring safety.
In addition, it is actually very easy to distinguish between electric hot water bottles with electrodes and electric hot water bottles with electric heating wires. Just squeeze the heating element in the hot water bottle. If the heating element is small, it is of the electrode type. If you can obviously touch a plastic coil device with a diameter of seven or eight centimeters, it is an electric heating wire hot water bottle. It should be noted that the hot water bottle should be gently shaken from time to time when charging, so as to ensure that the temperature of the water in the bag is very uniform. What must not be done is to use a hot water bottle when charging. In addition, when you sleep at night, you can't get close to the hot water bottle to prevent it from being crushed when you turn over, so that the hot water in the hot water bottle flows out and burns yourself. Therefore, as long as we use the electric hot water bottle correctly and be careful of the three kinds of injuries mentioned above, the electric hot water bottle is still a magic weapon for us to keep warm in winter.
Clever use of hot water bottles also has different effects: 1, applying back to relieve cough.
Fill a hot water bottle with hot water, wrap it with a thin towel or cloth and apply it to your back. It can dilate blood vessels and accelerate blood circulation in respiratory tract, trachea and lungs. This is mainly because the bladder meridian in the back circulation is mainly superficial, and the invasion of exogenous pathogens leads to aversion to cold and fever and nasal congestion; However, the Du meridian governs the yang of the whole body, and once it is invaded, the yang will weaken and the resistance will become lower; The lung points on the back have the function of treating lung qi failure. Therefore, often applying hot water bags to the back can not only make the bladder meridian and Du meridian work normally, but also make the lung acupoints stand guard actively, which is good for relieving cough, treating colds and improving resistance.
Step 2 relieve pain
24 hours after injury, when the swelling begins to improve gradually, hot compress local pain with hot water bag for about 20 minutes each time, 1-2 times a day, which can effectively promote blood circulation, accelerate the absorption of hyperemia exudate, play the roles of warming meridians, dispelling cold, promoting blood circulation and dredging collaterals, and relieve local swelling and pain.
3, the application of neck hypnosis
The neck has rosis, which is mainly used for insomnia and dizziness. Put the hot water bottle on your back neck before going to bed, and you will feel gentle and comfortable. First your hands will get hot, and then your feet will feel warm, which can play a hypnotic role. In addition, applying a hot water bottle to the neck can also affect Dazhui point, so it also has a good effect on treating cervical spondylosis.
In addition, there are six meridians such as spleen, liver, kidney, stomach, gallbladder and bladder, and there are more than 60 acupoints on the feet. Hot compress on the foot can also dredge the meridians, activate the acupoints, and finally achieve the effect of warming up. The water temperature in the hot water bottle should not be too high, generally 60℃-70℃ is appropriate. Be sure to check the tightness of the plug before use, and it is best to wrap it with a towel before use.
Matters needing attention in using hot water bottle
Hot water bottles are not suitable for everyone. For patients with diabetes and peripheral sensory nerve retardation and infants, it is best not to use hot water bottles for heating. Because of the weak blood circulation of diabetic limbs, accompanied by peripheral neuropathy, the adjustment and sensitivity to temperature are weakened, and it is easy to burn or scald when using hot water bottles. At the same time, remind elderly friends with diabetes that if you need to use hot water bottles to keep warm, it is best to wrap them with thick cotton cloth to avoid direct contact. In addition, it is best to control the water temperature at about 40℃ when soaking feet, so that the temperature will not be too high.
Tips: You need to pay attention to some matters when using hot water bottles to avoid being affected by warmth. You should also pay attention to controlling the water temperature and checking the hot water bottle to avoid water leakage and burns, which are prone to some accidents. I hope you can understand the use of some hot water bottles as soon as possible.
