physical coolingPhysical cooling refers to the method of reducing the temperature of objects by physical heat absorption or dissipation. It can be used to cool patients with high fever. For example, cooling the head can prevent cerebral edema, reduce brain cell metabolism, and improve the tolerance of brain cells to oxygen deficiency. The methods included the following:
- Rubbing bath method: such as warm water rubbing bath, alcohol rubbing bath, Chinese medicine liquid rubbing bath. Warm water of 30 - 37 degrees Celsius was generally chosen for the warm bath, because cold water was highly irritating and would shrink pores, which was not conducive to heat discharge, and may aggravate the condition. Alcohol bath was not common because of the allergy of some people. If it was used, it was the same as wiping with a towel. It was not recommended to use the bath method for physical cooling in infants and patients with blood diseases.
- Ice compress cooling method: like ice pack cooling, ice cap cooling, etc., can wrap the ice with a towel to cool the armpit, neck and other large blood vessels of the patient with fever. Pay attention to avoid direct contact with the ice to prevent frostbite.
- Venous cooling.
- Enemas.
- Medical ice blanket cooling method, etc.
In the process of physical cooling, there may be local frostbite, diarrhea, cardiac arrest, general reactions, subcuticular bleeding, local pressure sores, alcohol allergy, chemical cooling bag fluid extravasation and skin damage, and other complications. It needs to be treated according to the specific symptoms. In addition, if physical cooling fails to reduce the body temperature to normal in a short period of time, it is recommended to go to the hospital in time to avoid delaying the illness.

5 methods of physical coolingHere are five physical cooling methods:
1. Wiping bath method:
- Warm Water Wipe Bath: Use warm water of about 32 - 34 ° C to wipe the patient's skin all over the body. The wiping time can be slightly longer on the armpits, groin and other parts with rich blood vessels. It is best not to wipe the chest, abdomen and other parts sensitive to cold stimulation.
- Alcohol scrub (Due to alcohol allergy in some people, use with caution): The wiping area is similar to a warm water scrub.
2. Ice compress cooling method:
- Ice bag cooling: wrap the ice with a towel and place it on the armpits, neck, and other large blood vessels of the feverish patient to cool down. Pay attention to avoid direct contact with the ice to prevent frostbite.
- Ice cap cooling: It can cool the head. For example, wearing an ice cap on the head can prevent cerebral edema, reduce brain cell metabolism, and improve the tolerance of brain cells to oxygen deficiency.
3. Room temperature adjustment: Maintain the room temperature at around 25°C. At the same time, maintain appropriate ventilation in the room to help the patient dissipate heat and cool down.

Mobile phone cooling functionThere were many ways to cool down the phone:
- ** In terms of hardware **:
- Some mobile phones used water-cooling technology to cool down, which was to design a water-cooled heat dissipation pipe on the CPU heat sink, which was fully integrated with the graphene heat sink parallel to the main board to conduct the CPU heat to the outer casing.
- You can use professional phone cooling back clips, metal cooling supports, and other accessories to help the phone dissipate heat with the help of thermal and thermal principles. For example, the Nishen water cooler could be directly attached to the phone or fixed to the phone through a clip. It could cool down 45 degrees in 46 seconds, and the temperature could be adjusted freely. It was suitable for Apple and Android phones.
- ** Software **:
- Some phones had their own cooling function, such as the Vivo phone, which could wake up the small V. The voice input could also shorten the automatic lock screen time to 30 seconds and click a button to cool down.
- There were special cooling applications for mobile phones, such as Coolify, which used unique technology to reduce the heat generated by the system and help keep the phone temperature in the normal range. However, the effect may vary according to individual usage and device model.
- He could reduce the heat of the phone through software optimization, such as turning on low-battery mode or automatically adjusting screen brightness to reduce the power consumption of core components such as CPU and CPU, and turning off unnecessary background applications to avoid excessive resource consumption.
- ** Usage Habits **:
- You can perform one-click power-saving optimization, that is, click on the settings-battery-one-click power-saving, detect the phone status and manually select the optimization item according to the prompt; or directly turn on the power-saving mode or super power-saving mode to reduce power consumption and heat, but it may affect the user experience.
- During daily use, don't play with your phone while charging, clean up unused background applications in time, don't play music and videos at a high volume for a long time, and try to avoid surfing the Internet in places with poor signal.
- ** Regarding environmental conditioning **: Move the phone to a cool and well-vented environment, such as indoors, in a cool place, or use cooling equipment such as a small fan. Do not place it in direct sunlight or in a confined space. The phone itself also had an automatic temperature control function. When it detected that the internal temperature was too high, it would automatically reduce the frequency and screen brightness to protect the phone hardware.

Physical cooling and fever reductionThere were many ways to lower the temperature physically. The first method was to replenish fluids and drink warm water. This was a more effective method. The second method was wet compress. A wet towel could be placed on the forehead, wrists, and calves, and other parts could be covered with clothes. The third method was the rubbing bath method. For example, the warm water rubbing bath at 38 - 40 ° C had an obvious cooling effect. It could also use alcohol rubbing bath and Chinese medicine rubbing bath. The rubbing bath site could choose the distribution area of the human body's large blood vessels, such as the head, armpits, neck, etc. The fourth was ice compress cooling method, including ice bag cooling, ice cap cooling, such as wrapping ice cubes with towels to cool down the armpits, neck and other large blood vessels of patients with fever. Pay attention to avoid direct contact with the skin to avoid frostbite; You can also use physical cooling headband cold compress (put the headband into the freezer of the refrigerator to freeze before use). The fifth was to adjust the indoor temperature. It was recommended that the room temperature should not exceed 20 ° C, and at the same time, maintain moderate ventilation in the room. Sixth, reduce the patient's clothing and do not lower the patient's temperature by covering his sweat. Seventh, for children, when they have a low fever, they can take a warm bath of about 34 - 36 ° C (2 - 3 ° C lower than the child's body temperature) for about 15 minutes. During this period, close the doors and windows to avoid direct wind or breeze. Eight, you can give the child more hot water, wash his feet with warm water, rub his hands and feet hot, put an ice water pillow under his head and neck, use a towel to apply cold compress on his head, paste a fever paste on his forehead, and so on. However, physical cooling is not recommended for infants and patients with blood diseases. If physical cooling cannot bring the body temperature down to normal in a short period of time, it is recommended to go to the hospital in time to avoid delaying the illness. In the process of physical cooling, there may be local frostbite, diarrhea, cardiac arrest, general reactions, subcuticular bleeding, local pressure sores, alcohol allergy, chemical cooling bag fluid extravasation and skin damage, etc., which should be treated according to the specific symptoms.
