The four words that the heart fears most during the dog days of summer are actually

As we enter the dog days of summer, the first thing that comes to mind is that cardiovascular and cerebrovascular patients should pay attention to cooling down and preventing heatstroke. However, few people know that cardiovascular and cerebrovascular patients are more afraid of these 4 things.

cold

The most suitable ambient temperature for the human body is 22-23℃. If the air-conditioning temperature is too low, the instantaneous temperature difference when entering indoors from outdoors can easily cause strong contraction or spasm of blood vessels. For heart patients, the strong contraction of blood vessels can cause the plaques formed in the coronary arteries to be pulled and ruptured, causing blood clots, blocking blood vessels, and thus causing myocardial infarction.

In addition, long-term use of air conditioning can easily cause cold wind and wind invasion, which can lay the root cause of rheumatic heart disease.

The right approach

When using air conditioning, the indoor temperature should be between 25 and 27 degrees Celsius, not lower than 20 degrees Celsius; open windows more often to keep the indoor air fresh. It is best to keep the windows open and ventilated 2 to 3 times a day. The air conditioner should not be turned on for a long time. When you come back from outside and sweat a lot and enter the air-conditioned room, you should take off your wet clothes immediately and wipe off the sweat as soon as possible.

thirsty

For people with cardiovascular and cerebrovascular diseases, it is very necessary to consume an appropriate amount of water every day. Especially in summer, a large amount of water in the body will evaporate. If you do not replenish water in time, cardiovascular and cerebrovascular events are very likely to occur.

However, even for patients with heart disease, there are differences in how much they drink:

When the coronary artery is not receiving enough blood, you need to increase your water intake appropriately every day to prevent excessive blood viscosity from leading to myocardial infarction. However, when heart failure occurs, you should not drink too much water. Because drinking too much water will increase the burden on the heart and worsen the condition.

The right approach

The daily water intake should be no less than 2000~2500 ml. You should drink a glass of water before going to bed at night and after getting up in the morning. You can also drink some water when you wake up in the middle of the night to reduce blood viscosity and prevent thrombosis. After sweating a lot, you should replenish water by gargling with water in small amounts several times to moisten your mouth and throat, then drink a small amount, rest for a while, and then drink a small amount again to replenish slowly.

Oil

Hot weather can cause people to lose appetite, so many people tend to have a "heavy taste" for food. However, experts suggest that summer diet should be light. Eating too much oil and salt will increase blood lipids and blood pressure, which is not good for cardiovascular and cerebrovascular health.

The right approach

The daily diet should mainly consist of fresh vegetables, fruits, soy products, etc., and appropriately increase the intake of foods rich in potassium and magnesium, such as celery, cucumber, garlic, mung beans and bananas. You should also eat lean meat and fish regularly to ensure protein intake; pay special attention to food hygiene, eat less food from food stalls and drink less cold drinks to avoid diarrhea, which can lead to electrolyte imbalance in the body and induce heart discomfort.

sugar

Hypoglycemia is one of the main risk factors for cardiovascular prognosis in diabetes, and will increase the mortality rate of patients with myocardial infarction. Hypoglycemia is more likely to occur in the summer, inducing angina pectoris and ischemic cerebrovascular disease.

The weather is hot and humid in summer, people generally have a decreased appetite and their carbohydrate intake decreases. In addition, with more outdoor activities, the utilization of blood sugar increases. At the same time, the daytime is longer in the summer, and it is easy to lack sleep in hot weather, which causes the body to dissipate heat, the body's metabolism to be vigorous, and the relative consumption of blood sugar also increases. Therefore, when measuring blood sugar, diabetic patients often find that blood sugar is lower in summer than in other seasons.

The right approach

Generally speaking, blood sugar levels in the summer are best controlled at around 6 mmol/L when fasting and between 8 and 10 mmol/L after meals. The incidence of hypoglycemia increases in the summer, and some patients need to adjust their glucose-lowering medications, but how to adjust glucose-lowering medications must be based on blood sugar monitoring, and the doctor must adjust the medication plan.
