The heart has an internal 'biological clock' that follows a fixed day-night rhythm, with a faster heart rate during the day and a slower heart rate at night. To protect the heart, it is important to know when it is most 'fragile.'
During sleep, the heart rate slows down. After a night of metabolism, blood may become thicker and flow more slowly, increasing the risk of vascular embolism. Upon waking, the sympathetic nerves become extremely active, leading to increased heart rate, elevated blood pressure, and emotional excitement. High-risk individuals with hypertension and dyslipidemia may trigger cardiovascular events if they hurry to start activities.
Advice: Do not rush to get up in the morning. Lie flat for a while to avoid sudden movements. Drink a glass of warm water after waking up, and choose a light, low-salt breakfast.
For people with high blood pressure, it is best to take antihypertensive medication on time after waking up to prevent blood pressure fluctuations.
During this period, blood pressure is usually higher, and the sympathetic nerves are excited, making people feel excited and agitated. At the same time, the muscles are active. These factors combined may cause vascular plaques to become unstable, increasing the risk of angina pectoris and myocardial infarction.
Advice: Avoid overeating at lunch, take a walk after meals, and try to nap for half an hour. When stressed or feeling low, try deep breathing to increase the oxygen content in the blood, keep the brain calm, and relax tense nerves.
After the morning's work, the body and brain may feel tired. By 4 PM, blood pressure begins to rise, which may trigger angina pectoris or myocardial infarction.
Advice: Take breaks during work to move around, and avoid overeating at dinner.
Before bed, avoid prolonged use of mobile phones. Instead, choose to read books or listen to light music to fully relax the body and mind for sleep.
