High blood pressure CAN cause insomnia.
More Info: Those suffering from insomnia are five times more likely to suffer from high blood pressure concluded a study conducted by Penn State College of Medicine.
Insomnia Causes Hypertension
Speaking of his findings at Sleep 2008, the annual meeting of the associated professional sleep societies, lead researcher Alexandros Vgontzas recounted his methods and results. Interviewing more than 1,700 people, Vgontzas grouped them according to sleep duration and efficiency and discovered that those that slept fewer than five hours per night were five times more likely to suffer from hypertension. Sleeping five to six hours raised the likelihood of hypertension three times, concluding that there is a definite link between insomnia and hypertension. [“Sleep” 2010]
Sleep Temporarily Lowers Blood Pressure
Though not directly related to high blood pressure, there is a connection between sleep problems and heart health. When you sleep, your blood pressure dips nearly 10%. According to research, this drop in blood pressure appears to play a role in cardiovascular health. If you suffer from a sleep disorder, and your blood pressure does not dip as it should, you have an increased risk of heart attack, stroke, irregular heartbeat, and angina.
