Uncontrolled hypertension can lead to dangerous diseases such as stroke, coronary heart disease, myocardial infarction and kidney failure, while poor control, resulting in large fluctuations in blood pressure, can also produce the above-mentioned hazards. Studies have shown that due to the abnormal auto-regulation function of hypertensive patients, a significant drop and rise in blood pressure can make the patient unable to bear it, causing symptoms such as insufficient blood supply to the brain, lack of oxygen and dizziness. In addition, modern medicine has also confirmed that: waking up early in the morning is the peak time period for hypertensive patients to have various cardiovascular and cerebrovascular accidents, if the blood pressure is not well controlled during this time, resulting in high blood pressure volatility, it will greatly increase the risk of stroke, etc., and in serious cases, even death. Therefore, it is crucial to lower blood pressure smoothly so that it is slowly lowered and kept under stable control throughout the day and 24 hours a day.
