Drinking water can also affect blood pressure? That's right! The drinking habits of hypertensive patients have a profound impact on their health status. Reasonable water intake not only helps maintain normal metabolism in the body, but also has a positive promoting effect on the stability of blood pressure. Today, Ren Xin, Deputy Chief Physician of the Neurology Department of the Emergency General Hospital, shared with hypertensive patients the ways to drink water in their daily lives, including the amount, temperature, type, and duration of drinking water. The amount of water intake is important. Hypertensive patients should not consume a large amount of water at once, as this can cause a sudden increase in blood volume, leading to fluctuations in blood pressure. Therefore, it is recommended that hypertensive patients adopt a small amount of drinking water multiple times, with each time drinking around 200 milliliters, and evenly distribute the drinking time within a day. This can ensure the body's water needs while avoiding drastic changes in blood pressure. The selection of water temperature is important. Hypertensive patients should avoid drinking water that is too hot or too cold. Hot water may damage the esophageal mucosa, increasing the risk of developing esophageal ulcers and even esophageal cancer; However, excessively cold water may stimulate gastrointestinal blood vessels, leading to vasoconstriction and causing discomfort in the stomach, which is not conducive to blood pressure control. Therefore, hypertensive patients should drink warm water at a temperature close to body temperature, which can maintain comfort and avoid adverse effects on blood vessels. Drinking plain water is the first choice, and there is knowledge about what kind of water to drink. Boiled water is not only pure and pollution-free, but also has good permeability and solubility, which can be quickly absorbed and utilized by the body. In addition, plain water can help dilute blood, reduce blood viscosity, and thus help lower blood pressure. In addition to plain water, hypertensive patients can also drink light tea in moderation. The tea polyphenols and catechins in tea have antioxidant, anti-inflammatory, and antihypertensive effects. Moderate consumption is beneficial for patients with hypertension. However, it should be noted that the concentration of tea should not be too high to avoid affecting sleep and blood pressure control. Drinking less water in the morning after waking up during these two hours can help replenish the water lost at night and promote the body's metabolism; Drinking water in the morning and afternoon can maintain the body's water balance and maintain normal physiological functions; Drinking water in moderation before bedtime can help prevent blood pressure fluctuations caused by dehydration at night. However, it should be noted that hypertensive patients should avoid drinking too much water half an hour before bedtime and waking up in the middle of the night to avoid affecting sleep quality and blood pressure control due to frequent nocturia. Pay attention to three details when supplementing water. Hypertensive patients should avoid drinking large amounts of cold water immediately after vigorous exercise or sweating to avoid stimulating blood vessels; In diet, it is important to consume foods rich in water, such as fruits, vegetables, etc., in moderation to increase the body's water intake; Regularly monitor changes in blood pressure, adjust drinking water plans and lifestyle habits based on blood pressure conditions. Finally, it should be emphasized that the drinking habits of hypertensive patients should be individualized. Everyone's physical condition and condition are different, so it is necessary to adjust the drinking water plan according to their actual situation. When adjusting drinking habits, it is recommended that hypertensive patients consult professional doctors or nutritionists to ensure the scientific and reasonable drinking water plan. (Lai Xin She)
