The hot and humid rainy season poses a challenge to blood pressure control, especially for elderly patients with hypertension who need to strengthen disease management. Experts suggest starting from six aspects to help patients pass the rainy season safely. Many hypertensive patients have reported that during the rainy season, they sometimes feel that their blood pressure drops during the day compared to the previous period, and some experience poor blood pressure control and large blood pressure fluctuations. It is worth noting that during the plum and rainy season, many people cannot sleep soundly, and their sleep quality becomes worse, which causes autonomic nervous function disorder, thus affecting Vasoconstriction, making the blood pressure rise at night, in a fluctuating trend. In addition, hypertension in the morning is the primary risk factor of cardio cerebral Vascular disease, and prevention should be strengthened. Early morning is a high incidence period for cardiovascular and cerebrovascular events, with peaks of sudden death, myocardial infarction, and stroke occurring 4-6 hours before and after awakening. The risk of ischemic stroke occurring in the early morning is four times higher than in other periods, and the risk of cardiovascular death increases by 70% between 7am and 9am compared to other periods. So, how can elderly patients with hypertension safely survive the rainy season? It is recommended to do the following: 1. Strengthen blood pressure measurement to increase the frequency of blood pressure measurement, especially during the first hour after waking up in the morning, before taking medication, and before breakfast. Early morning blood pressure is an important indicator for hypertensive patients and is closely related to cardiovascular and cerebrovascular complications. 2. Drink more warm water. The weather is sultry in the rainy season. The human body sweats a lot and loses water quickly. If you do not drink water in time, Hypovolemia will decrease, which will cause blood viscosity, thrombosis, and cerebral infarction and myocardial infarction. Drink small amounts of water multiple times. 200-300 milliliters per session, strive to consume around 2000 milliliters of water per day; Drink warm water instead of ice water to avoid cold stimulation, Vasoconstriction and elevated blood pressure. 3. Reasonable diet suggests that the daily salt intake of elderly hypertensive patients should be less than 6 grams. While reducing sodium salt intake, increase potassium salt intake to help reduce blood pressure. Potash rich foods mainly include fruits, vegetables, coarse grains, soy products, fish, etc. Reduce the intake of fat and Saturated fat acids, increase the intake of Unsaturated fat acids, that is, eat less "red meat" such as pigs, cows and sheep, and properly supplement high-quality proteins such as chicken, ducks, fish, bean products, dairy products, fungi, etc. 4. Regular aerobic exercise and proper aerobic exercise to maintain mental health can improve the regulating function of nerves and blood vessels and effectively reduce blood pressure. It is recommended to engage in slow paced, low-intensity aerobic sports for 30 minutes five times a week; Elderly people can choose activities that are more soothing, such as Tai Chi and slow walking. Emotional stability, willingness to communicate with others, and a state of anxiety and depression are also necessary conditions for controlling hypertension. 5. Follow the doctor's advice and use medication regularly. During the rainy season, blood pressure can easily fluctuate due to external factors. The level of self measured blood pressure does not mean that patients can decide to increase or decrease their medication at home. When blood pressure fluctuates, it is important to seek medical attention in a timely manner and strictly follow the doctor's instructions to take antihypertensive drugs. 6. Prevent accidents. Elderly people who seek medical treatment in a timely manner are often complicated with Atherosclerosis. The elasticity of blood vessels is poor, and postural blood pressure fluctuations are prone to occur. Remember "three and a half minutes": lie flat for half a minute after opening your eyes; Sit in bed for half a minute
