Summer has arrived, and the temperature and humidity in Lingnan area are high, making the human body prone to fatigue and discomfort. In such seasons, the risk of stroke will also increase accordingly. Stroke, also known as "stroke", is a serious cerebrovascular disease with high incidence rate, high disability rate, high mortality and high recurrence rate. Why does the incidence rate of stroke increase in summer? Can't you foolishly distinguish between stroke and heatstroke? Listen to experts from the Fifth Affiliated Hospital of Sun Yat sen University (CUHK Fifth Hospital) teach you how to distinguish. Why does the incidence rate of stroke increase in summer? 1、 High temperature weather leads to a significant loss of water in the human body, which can easily cause dehydration, increase blood viscosity, slow down blood flow, and increase the risk of cerebral vascular blockage. 2、 High temperature weather can easily cause fluctuations in human blood pressure, especially for patients with hypertension, which increases the risk of cerebral hemorrhage. 3、 In summer, people often have poor appetite, which can easily lead to malnutrition, affect physical health, and increase the risk of stroke. How to prevent stroke in summer? 1、 Maintain sufficient water intake by drinking at least 8 glasses of water per day, approximately 1500 milliliters, to replenish lost water in the body, reduce blood viscosity, and prevent cerebral vascular blockage. 2、 Reasonable diet arrangement: Summer diet should focus on light and easily digestible foods, eat more vegetables, fruits, and other foods rich in vitamins and minerals, and eat less greasy, spicy, and stimulating foods. At the same time, it is important to pay attention to dietary habits and avoid overeating. 3、 Control blood pressure and blood sugar For patients with hypertension and diabetes, they should take medicine on time, control blood pressure and blood sugar level, and avoid excessive fluctuations in blood pressure and blood sugar. 4、 Avoid prolonged exposure to high temperatures. In summer, try to avoid going out at noon and avoid prolonged exposure to high temperatures. If it is necessary to go out, take sun protection measures, such as wearing a hat, wearing long sleeved sun protection clothes, etc. 5、 Moderate exercise, although hot in summer, is essential. You can choose to exercise in the morning or evening, such as walking, jogging, swimming, etc., to enhance cardiovascular function and promote blood circulation. 6、 Maintain a good mindset. In summer, people are prone to feeling irritable and irritable. It is important to maintain a good mindset and avoid excessive emotional fluctuations; You can relax and relieve stress by listening to music, reading, traveling, and other means. Common symptoms of heat stroke include crooked corners of the mouth, unilateral weakness of the arm, and unclear speech. The common manifestations of heatstroke include fever, rapid pulse, loss of consciousness, etc., but there will be no signs of limb weakness, hemiplegia, etc. Director Zhang Lei of the Department of Cerebrovascular Diseases at the Fifth Hospital of CUHK reminds us not to mistake heat stroke for heatstroke. Many citizens feel dizzy and nauseous, thinking it is heatstroke and can be relieved by taking a rest. When the symptoms are severe, they go to the hospital for examination and find that it is a stroke. Once citizens notice dizziness, headache, nausea, vomiting, accompanied by numbness, weakness, and unclear speech, they should immediately call the emergency hotline and avoid delaying the best rescue time with an observational attitude. During the process of waiting for first aid, it is important to keep the patient's respiratory tract unobstructed and avoid suffocation. If the patient is conscious, they can be kept quiet to avoid excessive activity. Patients who have already experienced stroke should pay more attention to prevention work, regularly go to the hospital for re examination and follow-up, and be sure to promptly identify and deal with possible risk factors to avoid recurrence.
