What is a temperature below normal called?

People will catch a cold and have a fever if they do not pay attention to keeping warm at this time of the year. However, fever can be divided into high fever and low fever. So what is a low fever if the body temperature is lower than normal? How many degrees is a high fever? How to determine if you have a low-grade fever? What methods should we use to improve a low-grade fever?

What is a low fever? A low fever refers to a patient whose body temperature is abnormal but below 38°C, while a patient with a high fever is above 38.5°C. Low-grade fever is mostly 37.2℃～37.5℃ (axillary temperature). Among them, long-term low-grade fever refers to a fever that lasts for more than two weeks, but does not include intermittent fever. Low fever has physiological reasons as well as factors such as other diseases or infections. It is normal to have a headache or fever at ordinary times, but once you have a fever, especially a low-grade fever, the situation is not very good.

How to judge whether you have a low fever 1. Dizziness and swelling. Healthy people have very clear minds. Even when they are very tired, as long as they force themselves to be alert, their minds will immediately become clear. But once people find themselves feeling dizzy and confused, it is most likely a sign of fever. 2. Photophobia: People with a low fever are somewhat afraid of light, do not like being under the sun, and will feel very uncomfortable. 3. Chills When you have a low fever, the white blood cells in your body have actually begun to fight back, so the temperature inside the human body is higher. Once the outside temperature drops, the heat in your body will be conducted out, so you will feel cold. This method is best used for identification in the summer. If a person shivers when a cool breeze blows, he or she probably has a low fever. 4. Improved heat tolerance When you have a low fever, your heat tolerance will increase. For example, the temperature of the water you drink is higher than usual, the temperature of the bath water is higher, and once you finish bathing, you will feel a chill from the bones to the outside, as if something is taking the heat away from your body. 5. Take body temperature. Patients with a thermometer measuring body temperature below 38°C but above 37°C mostly have a low-grade fever. If you feel uncomfortable, use a thermometer to measure your body temperature as soon as possible. Check your body temperature at an appropriate frequency based on your feelings. Generally speaking, once in the morning, noon and evening is normal.

What to do if you have a low fever 1. Replenish fluids. For a low fever, you should pay attention to replenishing fluids, such as vegetable juice, scented tea, etc., to help sweating and prevent dehydration. Water has the function of regulating temperature, which can lower body temperature and replenish water loss in the body. The best way to test whether you are drinking enough water is to see if the color of your urine is clear. 2. Warm and moist compress: If the body temperature is not too high, you can use hot compress to reduce the fever. Use a hot, wet towel to repeatedly wipe the patient's forehead and limbs to dissipate heat from the body until the fever subsides. It is more appropriate to use warm water compress to help dissipate heat. Of course, if the body temperature rises above 39°C, do not use hot compresses to reduce the fever. Instead, use cold compresses to prevent the body temperature from continuing to rise. Method: Prepare warm water, the hot water temperature should be around 30℃. Undress, wet a towel, and rub your body up and down with the warm towel. Change towels every 10-15 minutes. 3. Sponge your whole body. Use a sponge to wipe your whole body. The evaporation can also have a cooling effect. After squeezing out excess water from the sponge, wipe one area at a time, keeping the rest of the area covered with clothing. Body heat evaporates this water, helping to dissipate heat. Note: Although alcohol evaporates more easily than water, it may cause discomfort to patients with fever. Do not wipe with alcohol. Furthermore, inhaling alcohol vapor or even absorbing alcohol through the skin is not good for the patient. 4. Take a warm bath. Taking a warm bath is the most comfortable thing. It can also help relieve fever symptoms. Taking a shower with hot water can actually help cool you down, just like drinking more warm water can detoxify you and lower your temperature. Generally speaking, you can take a bath when your body temperature is around 38 degrees, but the water temperature should not be too high. 32-34 degrees Celsius is more suitable. You should also eat something before taking a bath to prevent hypoglycemia. After bathing, dry your body and put on clothes as soon as possible to avoid catching a cold, which will aggravate the condition. In addition, keep an eye on the water temperature. If the water is cold, add some hot water in time.
