Long-term late-night rest after twelve o’clock has a certain relationship with high blood pressure Hypertension is a cardiovascular syndrome characterized by persistent elevation of blood pressure in the arteries of the body circulation, and it is currently believed that its etiology is the result of the joint action of certain genetic factors and environmental factors. Staying up late is a risk factor for hypertension. Staying up late can lead to hyperactivity of the sympathetic nervous system, which can excite the cardiac β-receptors, accelerate the heart rate, enhance myocardial contractility, increase cardiac output, leading to increased blood pressure; sympathetic neurotransmitters act on blood vessels, which can constrict arteries, promote vascular remodeling, and increase the resistance of peripheral vasculature, which is the structural basis for the maintenance and exacerbation of hypertension. Hypertensive patients should rationalize their work and rest, sleep before 10:00 p.m., with obvious symptoms such as dizziness, headache, panic, etc. It is recommended to go to the hospital in time.
