What is the cause of the child's unexplained fever?

Children's unexplained fever may seem inexplicable, but it is actually caused by many reasons. Most of the reasons are that children are growing. During this period, the brain center is unable to regulate body temperature effectively. At the same time, they are invaded by bacteria and viruses, which leads to body temperature imbalance and increases body temperature. Therefore, parents need to learn to judge what causes their children's fever and learn some measures to reduce their children's fever.

Guide to dealing with baby's fever: The temperature regulation center in the brain of infants and young children is less mature, so their control over body temperature is weaker. In addition, the body has poor resistance to viruses and bacteria, and its defense line is weak. Therefore, it is easy for the virus to invade the body's temperature center and cause a high fever without any prior signs. The most suitable temperature range for various functions and activities in the human body is approximately 36℃ ~ 37℃, so on average. Normal body temperature is considered to be around 36.5℃. Some non-disease factors can cause fever. When the ambient temperature is too high, the body temperature cannot dissipate, so it rises. This is called heat stroke.

During and after strenuous exercise, your body temperature will temporarily rise.

Brain injury or tumors can disrupt the function of the body's temperature regulation center, so the rise and fall of body temperature can vary greatly.

The effects of certain special drugs: such as atropin and anesthetics. Fever caused by disease is due to the release of toxins by various viruses or bacteria when they invade the human body. These toxins will change the temperature regulation center in the brain, causing it to mistakenly believe that 37°C should be 39°C or higher, just like the air conditioner setting has been misadjusted, thus causing the fever. There are many diseases caused by viruses or bacteria, such as colds, tonsillitis, tracheitis, pneumonia, gastroenteritis, encephalitis, etc., so when the above diseases occur, they will be accompanied by fever.

In addition, cancer or tumors may release certain toxins that cause the body's temperature regulation center to change its settings, thus causing inexplicable fever.
