Here’s another article which confirms what we already know: That lack of deep sleep can cause high blood pressure. We’ve known for years that sleep fragmentation can increase your adrenaline response at night during sleep, preventing the normal lowering of your blood pressure during sleep. Not having this “dipping” phenomenon is tied to having hypertension during the day.
If you look at this study in light of statistics from the CDC, the implications are frightening: Almost 1/3 of Americans have high blood pressure, and about 70% of these people are on medications, but less than 50% are being adequately controlled. Another 25% have pre-hypertension. Over 70% of people over 65 have hypertension. Take into consideration how sleep deprived we are as a society, and that 90% of people with obstructive sleep apnea are not diagnosed, this should be wake-up call for everyone.
