According to experts, supplementing enough water helps the body maintain a stable blood volume, thereby supporting the circulatory system to function more effectively. Nutritionist Dr. Lisa Young (University of New York, USA) said that dehydration can make blood more concentrated, causing the heart to work harder and can affect blood pressure.
Drinking a glass of warm water in the evening also helps the body relax, improve blood circulation and support metabolism. Warm water can help blood vessels dilate slightly, thereby contributing to improving blood circulation. This is especially beneficial for people at risk of high blood pressure or frequent stress.
In addition, the habit of drinking warm water before bed can also support better sleep. According to Dr. Michael Greger, a doctor and nutritionist in the US, quality sleep plays an important role in regulating blood pressure. When you don't get enough sleep or sleep poorly, the risk of high blood pressure can be higher.
However, experts emphasize that warm water is not a "therapy" for high blood pressure. The effectiveness is only supportive and needs to be combined with a healthy diet, salt reduction, increased exercise and weight control.
To achieve effectiveness, people should drink warm water in moderation in the evening, avoid drinking too much water close to bedtime to limit the impact on sleep. Maintaining this habit along with a scientific lifestyle will contribute to protecting long-term cardiovascular health.
