Mr. Lu is 60 years old this year and has just retired. He has always been a good health care worker. He also pays great attention to health care. He goes to the park every morning to exercise. However, Mr. Lu has had chest tightness, belching and other angina symptoms in the park in the morning. Strangely enough, the onset was limited to this period of time. Mr. Lu saw a lot of doctors and ate several anti-angina pectoris medicines. It was not very effective. Later, an expert suggested that he drink half a glass of water before going to bed. After urinating, I drink a small half cup after urinating. Since then, something magical has happened. Mr. Lu never had angina again.
Why does drinking water have such a "magic" effect? In fact, drinking water does not treat angina, but it can remove the cause of angina. When coronary artery stenosis, blood flow does not meet the needs of myocardial metabolism, causing myocardial ischemia and hypoxia, Angina pectoris is also produced. Some patients do not attack at ordinary times. Under conditions of labor, emotional excitement, full meals, cold, and rainy weather, coronary blood supply, oxygen deficiency, will produce angina symptoms. Water shortage is also one of them. One cause. The lack of water in the body can lead to blood concentration, increased circulation resistance, relatively reduced coronary blood flow, and increased myocardial hypoxia and induced angina. When a person enters a deep sleep state, sweating can cause the body to lose part of its moisture. Reduced; In addition, elderly kidneys have poor concentration function, and they need to bring out more water to excrete metabolites in the body. If you don’t pay attention to water, blood concentration will occur in the early hours of the morning, and angina pectoris will occur more easily in the morning. In this case, Timely, appropriate amount of water will help correct body fluid balance and relieve angina.
It should be noted that drinking water before going to bed can reduce blood viscosity and reduce the occurrence of angina pectoris. However, for patients with heart failure, drinking a lot of water at a time can easily increase the burden on the heart and even induce heart failure. It is recommended that people with heart disease control drinking water. Quantity and speed, To drink warm water, cold water may cause vasospasm and induce angina. Therefore, it is recommended that everybody (especially heart patients) wake up every night before going to bed and wake up in the morning and drink half a cup of warm water at a constant speed, with nocturia. Should also be appropriate amount of water. Usually we must always add water, do not wait until the tongue is dry before drinking water, which can avoid drinking too much water at one time, and in the premise of not increasing the burden of the heart to prevent angina.
