Back to our original question. Can a CPAP machine cause headaches? As it turns out, there is no solid proof that verified CPAP therapy as the cause of headaches. However, there is a connection. Or, at least, an indirect connection. Head discomfort is a common symptom of sleep apnea. This is the result of a reduction of oxygen flowing to the brain of a sleeper with sleep apnea.
The head discomfort comes in several different formats. It is usually a tension headache located in the forehead region or around the neck and back of the head. This happens when muscles tense up during a night of restless tossing and turning. The head pain may be in the form of a migraine. This is usually a throbbing pain that can be felt on both sides of the head or all over your head.
Another form of head discomfort is something called cluster headaches. These are characterized by intense pain behind or around one or both eyes for a substantial timeframe. Can a CPAP machine cause headaches? Well, actually, no they don’t. That is because one of the main reasons why you would use a CPAP machine is to sleep better which means the machine is reducing your odds of developing a headache.
