Uncle Li, a cardiovascular and cerebrovascular disease patient in his seventies, was sitting in a rocking chair at home, with a cup of tea that had been slightly cooled in his hand, and beads of sweat oozing from his forehead kept sliding down.
Although the air conditioner in his home was turned on at the right temperature, he could still feel the invisible pressure from the outside world, as if even the air had become heavy.
One: A heat wave is coming, and the health alarm is sounding
Uncle Lee is an old resident of the town, and he takes extra care of his body every summer.
But this year's scorching heat seems to be more difficult than in previous years, and the number of patients in the cardiovascular and cerebrovascular departments of the hospital has increased significantly, many of whom are old patients like Uncle Li.
One afternoon, Uncle Li suddenly felt chest tightness and shortness of breath, and his family rushed him to the hospital.
After an urgent examination, the doctor confirmed that it was due to the increased cardiovascular burden caused by the hot weather, which triggered angina.
This experience made Uncle Li and his family deeply aware that the threat of hot weather to cardiovascular and cerebrovascular patients should not be underestimated.
Doctor's in-depth analysis: the invisible killer in high temperatures
As the attending physician of Uncle Lee, I am well aware that the impact of hot weather on cardiovascular and cerebrovascular patients is multifaceted.
High temperatures can cause the body to sweat profusely, the blood becomes viscous, and the blood flow slows down, which increases the risk of thrombosis;
At the same time, high temperature will also increase the burden on the heart, increase the heart rate, and fluctuate blood pressure, which is easy to induce or aggravate cardiovascular and cerebrovascular diseases.
Therefore, self-care in hot weather is especially important for such patients.
In order to illustrate the problem more intuitively, I decided to take Uncle Li's experience as an example to reveal to you four things that cardiovascular and cerebrovascular patients should do less in hot weather.
Two: Taboos under the scorching sun: avoid excessive exercise
Uncle Li usually has the habit of exercising in the morning, but he still insists on it in the hot weather, which leads to an angina attack.
I told him that when the heat is high, the body's metabolism is faster, and the burden on the heart is already increased, and then vigorous exercise at this time is tantamount to adding insult to injury.
I advised him to switch to indoor light exercises, such as walking, tai chi, etc., and avoid the hottest time of day.
Three: the temptation of cold drinks: moderate amounts are appropriate
Uncle Li likes to drink ice-cold drinks to relieve the heat, but excessive intake of cold drinks will stimulate the vasoconstriction of the gastrointestinal tract, affect the secretion of digestive juices, and even cause gastrointestinal cramps, abdominal pain and other symptoms.
More importantly, after cold drinks enter the body, blood vessels will shrink rapidly and blood pressure will rise, which is extremely unfavorable to cardiovascular and cerebrovascular vessels.
I reminded him to drink plenty of warm water or weak tea in hot weather, and to avoid excessive consumption of cold drinks.
Four: the double-edged sword of air conditioning: rational use
Uncle Li's air conditioner is almost 24 hours a day, but staying in a low temperature environment for a long time will lead to too large temperature difference between indoor and outdoor, and the human blood vessels will frequently contract and relax, which is easy to induce cardiovascular and cerebrovascular diseases.
I advise him to keep the air conditioner at a suitable temperature (usually around 26°C), avoid blowing directly on his body, and open the windows regularly for ventilation.
Five: The powder keg of emotions: Stay at peace
Hot weather can easily make people irritable and irritable, and have great mood swings.
For cardiovascular and cerebrovascular patients, emotional agitation can lead to an increase in heart rate, increase blood pressure, and increase the risk of cardiovascular and cerebrovascular events.
I reminded Uncle Li to learn to regulate his emotions, maintain a calm mind, and relax his mind by listening to music, reading, etc.
Doctor's Message: Scientifically Escape the Heat and Protect Health
In hot weather, the health protection of cardiovascular and cerebrovascular patients is particularly important.
I appeal to patients and their families to pay close attention to the impact of hot weather on their health, avoid excessive exercise, consume cold drinks in moderation, use air conditioning rationally, and maintain a calm mind.
At the same time, it is necessary to pay close attention to the changes in the body, and seek medical attention immediately once there are uncomfortable symptoms such as chest tightness, shortness of breath, and dizziness.
Let's work together to create a safe and comfortable summer living environment for cardiovascular and cerebrovascular patients!
