In the mornings, I always get high blood pressure readings, while my readings are normal in the evening. What could cause high blood pressure Readings in the morning?
Serum cortisol—which activates the autonomic nervous system and can cause high blood pressure readings—peaks in the early morning hours.
Researchers speculate that the higher incidence of sudden cardiac death in the early hours of Saturday and Monday mornings may be due to excessive cortisol levels at that time. So ask your doctor to check your levels with a 24-hour salivary cortisol test (samples are saved every four hours for 24 hours) if you are experiencing morning high blood pressure readings.
