High temperature in summer is easy to induce cardiovascular and cerebrovascular diseases.

Temperature change is the "enemy" of cardiovascular and cerebrovascular diseases. Every summer, especially in July and August, is the peak period of the incidence and death of cerebrovascular diseases. Hot and sultry weather will not only shorten sleep time and reduce sleep quality, but also make people feel irritable and raise blood pressure. Studies have shown that when the temperature exceeds 35℃, the incidence of cardiovascular and cerebrovascular diseases will increase by 1 7.3% for every increase of1.

Why does temperature have such a great influence on the cardiovascular system?

First, the blood is sticky and the oxygen supply is reduced.

The high incidence of cardiovascular diseases in summer stems from the influence of high temperature on cardiovascular system. In summer, hot temperatures will lead to increased sweating, which will increase blood viscosity and block blood circulation. On the other hand, hot weather will accelerate human metabolism and increase the demand for oxygen, which will lead to a decrease in blood supply from the heart to the brain, thus causing ischemia and hypoxia. In addition, hot weather makes people feel irritable, which leads to cardiovascular emergencies such as myocardial infarction and stroke. Therefore, in the hot summer, we must pay attention to the cardiovascular situation and learn to cool the cardiovascular system, which is an effective way to prevent the onset of cardiovascular diseases.

Second, qi deficiency, gas consumption and body fluid injury.

From the perspective of Chinese medicine, the same is true. The hot climate will make people weak in vital qi, consume qi and damage body fluids, resulting in "qi and blood meridians are blocked", which will lead to myocardial ischemia, arrhythmia, elevated blood pressure, and even cardiovascular and cerebrovascular accidents due to intracranial hemorrhage or myocardial infarction. Therefore, in summer, patients with cardiovascular and cerebrovascular diseases should remind themselves to pay attention to physical changes, and they can also use some traditional Chinese medicine lifestyle to spend the summer heat safely.

How to protect cardiovascular health in summer?

First, eat more fruits and vegetables in a light diet.

In summer, the human body sweats more and loses more water. Drinking a glass of water in the morning can replenish the water evaporated from the skin at night. Diet should be light and rich in fiber. You can eat lotus seeds, lilies and mung beans, and eat more fresh fruits, vegetables and bean products. Avoid greasy, spicy and cold food, so as not to cause gastrointestinal discomfort and intestinal spasm.

Second, the indoor temperature should not change suddenly.

Use the air conditioner correctly in summer, and the temperature of the air conditioner should not be too low, just 26. The indoor and outdoor temperature difference should be controlled within 7. If the temperature difference between indoor and outdoor is too large, frequent access can make blood vessels contract and expand suddenly, resulting in vascular circulation disorder, thus increasing the burden of cardiovascular and cerebrovascular diseases. Open the window for half an hour every 2~3 hours to improve the indoor environment and reduce the indoor microbial concentration.

Third, it is not advisable to get up early to exercise.

Sultry summer and strenuous exercise can cause sympathetic nerve excitement, increased heart rate, increased blood pressure, increased oxygen consumption of cardiovascular and cerebrovascular diseases, and induce myocardial ischemia and insufficient blood supply to the brain. It is not advisable to get up early to exercise. Aerobic exercise can be done for 30 minutes at night. Elderly patients can choose jogging, walking and Tai Ji Chuan.

Fourth, be emotionally stable and take medicine on time.

Try to avoid mood swings, impatience will breed internal fire, and excessive tension, anxiety and irritability will also increase adrenaline secretion, leading to an increase in heart rate and blood pressure, which will have adverse effects. In hot summer, patients with cardiovascular and cerebrovascular diseases should take medicine on time and keep a peaceful and happy mind and mood.

In addition to the above, we should also pay attention to a light diet, eat more fresh vegetables, fruits and beans, get high-quality protein from lean meat, milk and eggs, and eat less or no foods with high fat, salt and sugar, so as to avoid raising blood lipids and affecting cardiovascular health. In summer, we should pay attention to food hygiene, reduce the frequency of eating out, especially eat less barbecue and smoked food and drink less cold drinks, so as not to cause diarrhea, disturb electrolytes and increase the burden on the heart. In addition, keep a calm mind and eliminate bad emotions such as anxiety or fear in time.

Therefore, in the hot summer, elderly friends with cardiovascular and cerebrovascular diseases should go out as little as possible, have a light and greasy diet, and work and rest regularly. Always protect your cardiovascular and cerebrovascular diseases.
