Headaches caused by blowing a fan can be relieved by changing the method of blowing the fan or stopping the fan and taking medication to relieve the pain.
Prolonged fan blowing can lead to headaches caused by coldness in the head and tension in the head muscles. You should stop continuing to blow the fan straight and change the speed and size of the wind. If there is water in your hair, you should first dry the water from your hair immediately with a hair dryer.
If the headache is severe, medication can be used to relieve the symptoms of the headache. Commonly used medications include oral ibuprofen, acetaminophen, treprostinil, and ergot. Massage can also be performed to relax the head muscles.
Normally, the head should be avoided from cold, and medications should be used under the guidance of a medical professional.
