心脑血管疾病高发季，出现这四个症状要重视

Core Viewpoint - The transition from summer to autumn increases the risk of cardiovascular diseases due to temperature fluctuations, requiring preventive measures and timely medical attention for symptoms [1]. Group 1: Increased Risks - The change in weather leads to significant temperature differences, which can elevate the risks of hypertension, heart attacks, and strokes [1]. - Blood viscosity changes during this season can increase the risk of thrombosis, especially if hydration is not maintained after outdoor activities [4]. - Respiratory infections are more common during seasonal transitions, which can exacerbate existing cardiovascular conditions, particularly in the elderly or those with weakened immune systems [5]. Group 2: Preventive Measures - Maintaining a healthy diet is crucial, emphasizing low salt and fat intake while avoiding high-oil and high-salt foods. It is recommended to consume fiber-rich foods and quality proteins while controlling fruit and sugar intake [6][7]. - Dressing in layers, known as the "onion method," is advised to adapt to varying temperatures throughout the day, particularly for the head, neck, and hands [8]. - Regular and moderate exercise is encouraged, with recommendations to avoid early morning workouts in colder temperatures, opting for late morning or early evening instead [9][10]. - Creating a comfortable sleep environment is important, with suggestions to maintain humidity and control room temperature between 18-22°C to ensure quality sleep [11][12][13]. - Monitoring blood pressure and blood sugar levels is essential, especially during significant weather changes, to adjust treatment plans as necessary [14][15]. - Maintaining a regular sleep schedule supports biological rhythms and cardiovascular health, with short naps recommended to stabilize blood pressure and heart rate [16][17]. Group 3: Symptoms Requiring Medical Attention - Symptoms such as significantly elevated blood pressure, persistent chest pain, nighttime breathing difficulties, and sudden physical impairments should prompt immediate medical consultation [18].
