If you have a fever, you should apply cold or hot water

In general, this situation should be compressed with hot water, which can quickly evaporate the water and take away the heat, although cold water makes the patient feel cool, but it does not have much effect on the heat dissipation in the body. Of course, if it is particularly severe, you will need to go to the hospital for an infusion**.

There are two common methods of cold compresses: "dry and wet".

Dry cold compress. In an ice pack made of rubber (or substitutes such as rubber gloves), fill half a bag of crushed ice (or ice water or cold water), tie the bag tightly, and separate it between the ice pack and ** with a towel or cloth cover. The interval between cold compresses is generally 1-2 hours, each application is 20 minutes, and it can be effective many times a day.

Wet cold compress. Soak two small towels or gauze in a basin of cold water (ice cubes if there is ice, or freshly beaten well water if there is no ice), take turns to wring it out until it is semi-dry and apply it to the affected area. 4 5 minutes to change the compress, 20 to 30 minutes each time, several times a day.

If the injured hand or foot is injured, you can also soak the injured hand or foot in cold water for no more than 15 minutes at a time.

There are also two common methods of hot compresses: "dry and wet".

The first is the dry heat compress method. Here's how to apply a hot compress with a hot water bottle: fill 60 70 hot water with 2 3 of the capacity of the hot water bottle, expel the gas, and tighten the mouth of the bag (be careful not to leak).

Put the hot water bottle into a cloth cover or wrap it in a cloth and apply it to the affected area, usually 20 to 30 minutes each time, 3 to 4 times a day. If you don't have a hot water bottle, you can also use a metal kettle (be careful to wrap it in a towel) or put hot salt or rice or sand in a cloth bag instead.

The second is the moist heat compress method. Soak two small towels or gauze in a hot water basin in advance, take them out in turn and wring them until they are semi-dry, test whether the temperature is appropriate with the palm side of your wrist (it must not be applied to the affected area when it is not hot), and then cover it with a cotton pad to prevent heat from dissipating, change it about every 5 minutes, a total of 20 30 minutes. It can be applied 3 to 4 times a day.

The specific method to use still needs to be considered in combination with the condition and the actual situation.

In fact, ice and heat can be, mainly depending on the personal situation at the time, if the temperature is not very high, the hands and feet can be cold, sometimes you can use cold towels with parents, and if the temperature is very high, the fever level of people is not the same, it is best to use hot water under the armpits, so that the cooling effect will be better, and it is safer.

1. The specific situation is analyzed as follows:

1. Use a hot towel when the body temperature rises:

2) This is generally in the early stage of fever, such as when measuring body temperature, the first measurement is 38, and after a while, it becomes 39, which is in the "period of rising body temperature". At this time, use a hot towel.

2) Because when a person's body temperature rises, the body surface needs heat, and if you use a cold towel to compete for heat, it will only make the body temperature rise faster. Therefore, when the body temperature of fever rises, you must use a warm towel, in addition to putting a towel on the head, you can also wipe the belly sockets, armpits, leg sockets and other areas where large blood vessels are distributed. In this way, even if the body temperature will rise, it will not rise too quickly.

2.Cold towels can be used during periods of stabilization, dropping, or later stages of body temperature:

1) This is usually when the fever lasts for a certain period of time, when the body temperature is in a stable period. For example, if the fever persists at 39 for a short period of time, this indicates that the central medium of the fever has been released or has been temporarily over. At this time, you can apply a cold towel or ice pack to your head, or use a cold towel to wipe the armpits, neck, leg sockets and other areas where large blood vessels are distributed.

2) This can help to cool down the fever and also prevent the body temperature from rising again. In addition, it is the late stage of fever, that is, the period of body temperature drop, at this time the body slowly dissipates heat, you can use a cold towel, this period is characterized by the predominance of the heat dissipation process, resulting in the source of the fever is gradually decreasing, at this time with Xianling cold towel, can help heat dissipation, so that the fever fades a little faster.

2. Problems to pay attention to when you have a fever.

1. Mild fever. Don't rush, drink plenty of hot water and get some fresh air. The body's own immune function will solve the problem. Don't be tired at this time, with a certain amount of rest and physical adjustment, you will soon return to normal.

2. Seek medical treatment in a timely manner. The body temperature is over 38. At this time, we should see a doctor in time and let the doctor judge how to **, or take medicine, or injections, and strive to ** as soon as possible**.

3. Bed rest, drink more water, eat a light diet, keep the skin clean and dry, wear cotton underwear, see a doctor in time, take medicine obediently, monitor the change of body temperature every day until normal, maintain emotional stability, and be optimistic and positive.

Cold or hot water for fever? This is a question that has caused many people to suffer. Most people may choose to apply hot water to their forehead, believing that hot water can dilate blood vessels, promote blood circulation, and speed up the body's metabolism. But there are also some people who believe that cold water can relieve headaches.

Actually, the correct answer is: it depends. If your body temperature is too high, it is recommended to apply cold water to your forehead, which will cool your body temperature down. If you're just feeling a little uncomfortable, but your temperature isn't elevated, then applying warm water to your forehead may be more appropriate.

Everyone's constitution is different, so it is recommended to test before use. Touch your forehead with your hands, and if you feel very hot, you should use cold water to reduce the fever; If you feel only slightly uncomfortable, warm water can be used to relieve it.

During the period of teasing and recuperating the fever, you should also drink more water, rest well, adjust your diet, etc., and pay more attention to your body. It is also important to pay attention to the dosage and method of use when choosing a fever reducer.

When dealing with fever, we need to make the right choice according to our physical condition and actual situation. I hope everyone can stay healthy and prevent diseases.

A warm compress with a hot towel is required, not hot water.

Extended information: Choose the timing when using the physical cooling method. When to use physical methods to cool down, it is important to first understand the process of heating.

The process of heating is divided into:

The period of rising body temperature is characterized by greater heat production than heat dissipation. The child felt chills, no sweating, and **pale.

The duration of hyperthermia is characterized by the balance of heat production and heat dissipation at a high level, and the body temperature is maintained at a high state. Facial flushing, burning, dry lips, rapid breathing and pulse, and decreased urine output are present.

The depyretic phase is characterized by increased heat dissipation and normal heat production, and the return of body temperature to a normal regulatory level. This phase is characterized by profuse sweating and a decrease in temperature.
