Sleep apnea, the condition where interrupted breathing during sleep reduces the amount of oxygen available to your body, can negatively impact all body functions. Many people are aroused from sleep hundreds of times during the night due to disruptive breathing and are completely unaware of this in the morning. You have to be awake for 6 seconds before you realize and have memory that you were actually awake. Research presented at the 52nd annual meeting in June of the American Headache Society suggests that sleep deprivation changes protein levels in the body that are known to initiate and sustain pain. These same proteins are thought to be a critical part of the migraine headache condition. Talk to your doctor about referring you to a sleep clinic for a sleep study, if you think you may have sleep problems.
