High temperatures in summer can easily induce cardiovascular and cerebrovascular diseases
Temperature changes are the "strong enemy" of the cardiovascular and cerebrovascular diseases. Every summer, especially July and August, is a small peak period for cerebrovascular disease attacks and mortality. High temperature and muggy conditions not only shorten sleep time and reduce sleep quality, but can also make people feel irritable and increase blood pressure. Studies have shown that when the temperature exceeds 35°C, the incidence of cardiovascular and cerebrovascular diseases will increase by 17.3% for every 1°C increase.
Why does temperature have such a great impact on cardiovascular disease?
1. The blood is thick and the oxygen supply is reduced.
The high incidence of cardiovascular disease in summer is due to the impact of high temperature on cardiovascular disease. In summer, hot temperatures will cause increased sweating, which will increase the viscosity of the blood. As a result, blood circulation will be blocked. On the other hand, hot weather will speed up the body's metabolism and increase the body's demand for oxygen, which will reduce the blood supply from the heart to the brain, causing ischemia, hypoxia and other conditions. In addition, hot weather can make people feel irritable, which can lead to cardiovascular emergencies such as myocardial infarction and stroke. Therefore, in hot summer, you must pay attention to your cardiovascular condition and learn to cool down your cardiovascular system, which is an effective way to prevent the onset of cardiovascular disease.
2. Deficiency of upright qi, depletion of qi and damage to body fluids
This is also true from the perspective of traditional Chinese medicine. Hot weather will cause people to have a deficiency of righteousness, depletion of qi and damage to body fluids, resulting in "qi" "The blood meridians are clogged and blocked", leading to myocardial ischemia, arrhythmia, elevated blood pressure, and even cardiovascular and cerebrovascular accidents due to intracranial hemorrhage or myocardial infarction. Therefore, in summer, cardiovascular and cerebrovascular patients should remind themselves to pay attention to physical changes, and they can also use some health care methods of traditional Chinese medicine to survive the heat safely.
How to protect cardiovascular health in summer?
1. Eat a light diet and eat more fruits and vegetables
In summer, the human body perspires a lot and loses a lot of water. Drinking a glass of water in the morning can replenish the moisture evaporated from the skin at night. In terms of diet, it is appropriate to have a light and high-fiber diet. You can eat lotus seeds, lilies, and mung beans, and eat more fresh fruits, vegetables, and soy products. Avoid oily, spicy, and cold foods to avoid causing gastrointestinal discomfort and intestinal spasm.
2. The indoor temperature should not change suddenly
Air conditioners should be used correctly in summer. The air conditioner temperature should not be turned on too low, 26 is enough. The temperature difference between indoor and outdoor should be controlled within 7 degrees. If the temperature difference between indoor and outdoor is too large, frequent entry and exit can cause blood vessels to suddenly contract and expand, causing blood vessel circulation disorders, thus increasing the burden on cardiovascular and cerebrovascular systems. Every 2 to 3 hours when the air conditioner is turned on, windows should be opened for ventilation for half an hour to improve the indoor environment and reduce the concentration of microorganisms in the room.
3. It is not advisable to get up early to exercise
The weather in summer is sultry and strenuous exercise can cause sympathetic nerve excitement in the body, increase heart rate, blood pressure, and increase cardiovascular and cerebrovascular oxygen consumption. , inducing myocardial ischemia and insufficient blood supply to the brain. It is not advisable to get up early to exercise. 30 minutes of aerobic exercise in the evening is enough. Elderly patients can choose jogging, walking, Tai Chi, etc.
4. Keep your mind stable and take medicine on time
Try to avoid mood swings. Impatience can breed internal fire. Excessive tension, anxiety, and irritability can also increase the secretion of adrenaline and cause heart rate. , blood pressure increases, causing adverse effects. Summer is hot, and patients with cardiovascular and cerebrovascular diseases should take their medicines on time and maintain a peaceful and happy mentality and mood.
In addition to the above points, you should also pay attention to a light diet, eat more fresh vegetables, fruits and beans, get high-quality protein from lean fish or milk and eggs, and eat less or no Eat foods with high greasy, high salt and high sugar content to avoid raising blood lipids and affecting cardiovascular health. In summer, you should also pay attention to dietary hygiene and reduce the number of meals you eat out. In particular, eat less barbecued and smoked foods, and drink less cold drinks to avoid causing diarrhea, disrupting electrolytes, and increasing the burden on the heart. In addition, keep a calm mind and eliminate negative emotions such as anxiety or fear in a timely manner.
Therefore, in the hot summer, elderly friends with cardiovascular and cerebrovascular diseases should go out as little as possible, eat light and less greasy, and have a regular work and rest schedule. Always protect your cardiovascular and cerebrovascular systems.
