Should I cool my forehead if I have a fever?

　　fever If so, you should cool your forehead

　　Reality: Even if you use an ice pack to cool your forehead, it has no cooling effect.

　　Many people suffer from cold After you have a fever, you will use a cold towel or other things to apply cold compress to your forehead. In fact, this approach is wrong. This is because if you want to reduce fever, you must lower the temperature of the blood, but there are no relatively thick blood vessels on the forehead, so it cannot effectively reduce fever and temperature.

　　It should be noted that the key to reducing fever is to "lower the temperature of places with thick blood vessels." So which place will be more effective? We can focus our attention on the sides of the neck, armpits and other places with thick blood vessels. Ice application in these places will have a better cooling effect than the forehead.
