Be on guard against heart disease when it is hot. How to protect and nourish your heart?

Recently, in the hot summer, cardiovascular patients have become the "mainstream" of hospital outpatient and emergency departments. So, how to protect the "fragile" heart and spend this hot summer safely? Medical research shows that environmental temperature is closely related to human physiological activities. The most comfortable ambient temperature for human body is between 20℃ and 28℃. When the ambient temperature is higher than 28℃, people will feel uncomfortable. No matter how high the temperature is, it will easily lead to irritability, heatstroke and mental disorders; Above 30℃, the human body will partially start sweat glands to discharge body heat, and at 35℃, all sweat glands will be put into work; The temperature is higher than 35℃, accompanied by frequent heat waves, which can also cause a series of diseases, especially the incidence of cardiovascular and cerebrovascular diseases and respiratory diseases, and the mortality rate is obviously increased. High temperature above 37℃ is harmful to human protein. If the temperature of human body reaches above 40℃, the life center will be directly threatened. Cardiology experts say that in summer, especially when the weather continues to be sultry, human metabolism and blood circulation are obviously accelerated, subcutaneous blood vessels are dilated, blood flow is 3-5 times higher than usual, and heart load is obviously increased. Because the human body sweats a lot, the water in the body evaporates with the sweat, which leads to blood viscosity, which is easy to form cardiovascular and cerebrovascular ischemia and even embolism. In addition, hot weather is easy to make people suffer from "emotional heatstroke", resulting in upset, impatience, anger and other emotions. This is because hot weather will affect the emotional regulation center of human hypothalamus and have a negative impact on people's psychology and emotions. "Emotional heatstroke" patients are prone to angina pectoris, arrhythmia, cerebral infarction, myocardial infarction and other diseases, and even sudden death. In order to prevent "emotional heatstroke", we should pay special attention to meditation and health preservation, and avoid being impatient and angry when things happen. So how should patients with cardiovascular diseases cope with such high temperature weather? Don't worry, Nurse Xiao Sheng will give you some advice ... 1. Avoid the air conditioner killer and pay attention to adjusting the indoor temperature. Indoor temperature should be 25 ~ 27℃, not less than 20℃; Dry the sweat before entering the air-conditioned room from the outside; Keep the indoor air fresh. Air-conditioned rooms should be ventilated regularly. It is best to keep the room ventilated 2 ~ 3 times a day. You shouldn't leave the air conditioner on all night when you sleep at night. 2. Pay attention to hydrating, sweating more in summer, which is easy to make blood sticky. Increasing heart pressure is not good for patients with coronary heart disease. Drink plenty of water. In summer, the amount of drinking water for adults is generally more than 2500ml, which can be judged by referring to the amount of urine (1500ml). Green tea is the first choice for warm drinking. Green tea has strong anti-oxygen free radical effect and good anti-cancer and anti-atherosclerosis effects. Drinking mung bean soup, lotus seed soup, lily soup and other drinks can replenish water and relieve summer heat, killing two birds with one stone. Try to avoid drinking ice water. Drinking a lot of cold drinks in a short time can induce angina pectoris and acute myocardial infarction. 3. In summer, people will lose appetite and have poor digestive function. At this time, for patients with coronary heart disease, we should pay attention to a light diet, eat more fresh vegetables and fruits, and eat some lean meat and fish appropriately. For high-fat, greasy food, try to eat less or not. 4. Pay attention to rest and have more rest. If you lack sleep, it will also affect the development of the cardiovascular system. If you go to bed late at night, you shouldn't get up too early in the morning. In addition, the death rate of coronary heart disease in people who take a nap for half an hour every day is 30% lower than that in people who don't sleep, which is related to the decrease of blood pressure and the slowdown of heart rate during nap. After waking up half an hour before going to bed or in the middle of the night and getting up in the morning, patients with coronary heart disease had better drink some boiled water in moderation. In addition, patients with coronary heart disease should keep their stools unobstructed and develop the habit of defecating regularly once a day. 5. Reduce outdoor activities When outdoor activities are carried out, patients with coronary heart disease should do a good job of heatstroke prevention and cooling, wear a sun hat and prepare enough water. When exercising, don't exercise in the hot sun to shorten the exercise time. If the weather is hot and humid, outdoor sports should be reduced or even stopped. Moderate exercise should be chosen at night. Although it is cool in the morning, 6- 1 1 in the morning is the peak time of acute myocardial infarction, stroke and sudden death, so it is not appropriate to arrange too many activities in the morning. 6. Quit smoking and limit alcohol. Patients with coronary heart disease must quit smoking. Smoking does great harm. Wine can be drunk properly, for example, wine should not exceed 50ml per day. 7. Peace of mind in summer, the weather is hot and dry, the air pressure is low, and the humidity is high. People are easily agitated in this season. In summer, patients with coronary heart disease should not only pay attention to their daily habits, but also try to keep their mentality calm. Only psychological balance can achieve physiological balance, ensure the normal function of various organs and smooth blood flow. 8. Take medicine according to the doctor's advice and see a doctor in time. In summer, the types or doses of drugs used by patients with coronary heart disease will be different, so it is suggested to make adjustments under the guidance of doctors. Summer is the season for traveling, and patients with coronary heart disease should carry anti-angina drugs with them when they go out for emergency treatment. At the same time, we should also know some common sense of coronary heart disease, so as to facilitate timely medical treatment once the condition changes.
