Be wary of heart disease in hot weather, how to protect and nourish your heart

Recently, in the hot weather, cardiovascular patients have become the "mainstream" of outpatient and emergency visits in various hospitals. So, how to protect your "fragile" heart and survive this hot summer safely? Medical research shows that environmental temperature is closely related to the physiological activities of the human body. The most comfortable ambient temperature for the human body is between 20°C and 28°C. When the ambient temperature is higher than 28°C, people will feel uncomfortable; any higher temperature will easily lead to irritability, heatstroke, and mental disorder; the human body will become unstable when the temperature is above 30°C. Sweat glands will be partially activated to discharge body heat. At 35°C, the body's sweat glands will all be put into work. Temperatures higher than 35°C, accompanied by frequent heat wave shocks, can also cause a series of diseases, especially the heart, cerebrovascular and respiratory systems. The incidence of disease has increased and mortality has increased significantly. High temperatures above 37°C will cause certain damage to human body proteins. If the human body temperature reaches above 40°C, the vital center will be directly threatened. Cardiology experts said that in summer, especially when the weather continues to be hot and muggy, the human body's metabolism and blood circulation are significantly accelerated, the subcutaneous blood vessels dilate, the blood flow increases 3-5 times than usual, the heart load increases significantly, and the heart burden increases. Because the human body sweats more, the body A large amount of water evaporates with sweat, causing the blood to become thicker, which can easily lead to cardiovascular and cerebrovascular ischemia or even embolism. In addition, hot weather can easily cause people to have "emotional heat stroke", causing them to feel upset, irritable, angry and other emotions. This is because hot weather can affect the emotional regulation center of the human body's hypothalamus, thus negatively affecting people's psychology and emotions. Patients who suffer from "emotional heat stroke" are prone to angina pectoris, arrhythmia, cerebral infarction, myocardial infarction and other diseases, and even sudden death. In order to prevent "emotional heat stroke", special attention should be paid to meditation and health preservation, to avoid irritability and anger when encountering problems, and to stay calm. So how should patients with cardiovascular disease cope in such hot weather? Don't worry, nurse Xiaosheng is here to give you some advice... 1. To avoid air-conditioning killers, pay attention to adjusting the indoor temperature. The indoor temperature should be 25 to 27°C, not lower than 20°C; wipe off the sweat before entering the air-conditioned room from the outside; keep the indoor air fresh, and open the windows regularly for ventilation in air-conditioned rooms. It is best to keep the temperature constant throughout the day. Open the window in the room 2 to 3 times for ventilation, and do not leave the air conditioner on all night when sleeping. 2. Pay attention to replenishing water. You sweat a lot in summer, and your blood tends to become sticky, which increases the pressure on the heart and is detrimental to patients with coronary heart disease. Therefore, you should drink more water. The amount of water consumed by adults in summer is generally more than 2500ml. You can refer to the urine output (1500ml) to judge. Green tea is the first choice to drink warmly. Green tea has strong antioxidant and free radical effects, and has good anti-cancer and anti-atherosclerosis effects. Drinking some mung bean soup, lotus seed soup, lily soup and other beverages can replenish water and relieve summer heat, killing two birds with one stone. Try to avoid drinking ice water. Drinking a large amount of cold drinks in a short period of time can induce angina pectoris and acute myocardial infarction. 3. Diet combination In summer, people will lose their appetite and their digestive function will deteriorate. At this time, patients with coronary heart disease should pay attention to a light diet, eat more fresh vegetables and fruits, and eat some lean meat and fish appropriately. Eat as little or no fatty and greasy food as possible. 4. Pay attention to rest and get more rest. If you don’t get enough sleep, it will also affect the development of the cardiovascular system. If you fall asleep late at night, you should not get up too early in the morning. In addition, those who take a half-hour nap a day are 30% less likely to die from coronary heart disease than those who don't sleep. The reason is related to the drop in blood pressure and slowed heart rate during nap. It is best for patients with coronary heart disease to drink some boiled water half an hour before going to bed or after waking up in the middle of the night or getting up in the morning. In addition, patients with coronary heart disease should maintain smooth bowel movements and develop the habit of defecating regularly once a day. 5. Reduce outdoor activities. When doing outdoor activities, patients with coronary heart disease should take precautions to prevent heatstroke and cool down, wear a sun hat and prepare enough water. When exercising, avoid exercising under the scorching sun and shorten the exercise time. If the weather is hot and humid, outdoor exercise should be reduced or even stopped. Appropriate exercise should be done in the evening. Although it is cooler in the morning, 6-11 am is the peak time for acute myocardial infarction, stroke, and sudden death, so excessive activities should not be arranged in the morning. 6. Stop smoking and limit drinking. Patients with coronary heart disease must quit smoking. The harm caused by smoking is very great. You can drink some wine in moderation. For example, wine should not exceed 50ml per day. 7. Peace of mind. The weather in summer is hot, with low air pressure and high humidity. People in this season are easily irritable and restless. In addition to paying attention to daily habits in summer, patients with coronary heart disease should also try to maintain a calm mind. Only psychological balance can lead to physiological balance. , ensuring normal function of various organs and smooth blood flow. 8. Take medicines as directed by your doctor and seek medical advice promptly. The type or dosage of medicines used by patients with coronary heart disease will be different in summer, so it is recommended to make adjustments under the guidance of a doctor. Summer is the season for travel again, and patients with coronary heart disease should carry anti-angina drugs with them when going out in case of emergency. At the same time, you also need to understand some common sense about coronary heart disease so that you can seek medical treatment in a timely manner once your condition changes.
