Don't think that the so-called brain burning is unscientific or just on TV. It is a terrible thing for a child to have a fever. Even adults don't want to do anything when they have a fever, let alone a child with low immunity. There is a child beside me who had a fever when she was a child, and her mother didn't pay much attention to it, thinking that it would be better to sweat. Unexpectedly, in the end, her intelligence will decrease. For us ordinary people, a cold can really cause fever or cooling. In fact, this is just a defense mechanism of the body. If the body temperature changes, it can improve immunity and give your brain an early warning.
For the average person, the fever caused by a cold is harmless, but if your body temperature has reached 40 degrees Celsius, it may bring great harm to your body.
If a child has a fever above 40 degrees Celsius, brain cells will be damaged to a certain extent. Everyone must pay attention to nerve cells. If there is damage, there is no way to regenerate, which means that the child's brain is burnt out.
