Do you Have High Blood Pressure?
Hypertension is commonly linked to sleep apnea. For the same reasons you experience headaches due to frequent pauses during sleep, you can get high blood pressure. As your brain wakes from sleep as it realizes that its not receiving adequate oxygen levels in the blood it causes a spike in blood pressure as it restricts your blood vessels to kick starts your system into working again. When this happens repeatedly throughout the night to combat every apnea event, your body gets used to having to restrict its blood vessels and high blood pressure begins to persist even during the day when you are breathing normally.
