Today, the heavy snow has blocked the roads and the temperature is extremely cold, bringing a lot of inconvenience to everyone's health and travel. Especially for some elderly people with cardiovascular and cerebrovascular diseases, under the stimulation of atmospheric pressure fluctuations and cold air, it is easy to induce or aggravate their conditions. In this regard, I would like to inform everyone that the biggest cause of cardiovascular and cerebrovascular diseases is the cold weather. Due to the large temperature difference between indoors and outdoors, the human body's blood vessels suddenly contract or dilate, making it easy for cardiovascular diseases to occur or recur. Below are a few things to be vigilant about:
1. Heart disease is more likely to occur in the early morning hours.
"When the weather changes, my heart feels uncomfortable, especially in the middle of the night." Recently, with the drop in temperatures in our province, many citizens with a history of heart disease have felt discomfort. In this regard, the early morning is a high incidence period for heart attacks. This is because at this time, the patient's vagus nerve excitability increases, blood flow slows down, and heart rate decreases, leading to sudden onset of heart disease. Especially when there is a sharp drop in temperature, the large temperature difference between indoors and outdoors makes it hard even for healthy people to adapt. For patients with a history of heart disease, it is easier for them to have an attack during this time. Additionally, patients with a history of heart disease should avoid catching a cold, as it can lead to lung infections, worsening heart function insufficiency, and ultimately causing a heart attack.
2. Dizziness and nausea should raise awareness of cardiovascular and cerebrovascular diseases.
Around 8 o'clock in the morning, heart attacks and strokes are also more likely to occur, because at this time the body's blood viscosity is high. If the movement is too intense or forceful, it can easily cause blood vessel rupture or insufficient blood supply to the heart and brain. Especially for the elderly, they should not get up too quickly after waking up in the morning, and the actions of dressing and getting out of bed should be gentle. Hypertensive, hyperlipidemic, hyperglycemic, and obese individuals should pay special attention to symptoms such as chest tightness, chest pain, dizziness, and nausea during the winter. Once these symptoms appear, they should immediately go to a regular hospital for treatment to prevent cardiovascular and cerebrovascular diseases. It is also important to not get up immediately when getting up at night, as sudden changes in posture can cause orthostatic hypotension, cerebral ischemia, dizziness, fainting, and lead to cardiovascular and cerebrovascular diseases. At the same time, whether patients have diseases or not, they should pay attention to their posture at night, and the normal posture is lying on the right side.
3. Cold weather should avoid walking against the wind.
Patients with a history of cardiovascular and cerebrovascular diseases, hypertension, diabetes, hyperlipidemia, myocardial damage, and other chronic diseases, once encountering cold weather, the risk of sudden myocardial infarction will increase. For the general population, they should actively keep warm, and in the particularly cold mornings, they should not walk against the wind or do morning exercises to avoid the stimulation of cold on the body's blood vessels. For patients with a history of hypertension, diabetes, cardiovascular and cerebrovascular diseases, they should try to reduce morning exercises as much as possible, preferably doing morning exercises when the sun is shining. When going out for activities, attention should be paid to keeping hands and head warm, and strenuous exercise should be avoided. In terms of diet, attention should be paid to eating less spicy and greasy foods, taking supplements in moderation, maintaining a peaceful mindset, and avoiding large emotional fluctuations. Once persistent chest tightness, angina pectoris, fever, arrhythmia, shock, heart failure, dizziness, headache, facial numbness, drooling, and other symptoms occur, they should immediately go to a regular hospital for treatment.
