Drinking water and choosing food to help stabilize blood pressure safely
Water does not directly lower blood pressure but helps maintain circulatory volume. Water deficiency will cause the body to constrict blood vessels, causing harm to the cardiovascular system. Drink enough to prevent dehydration and stabilize heart rate, depending on personal condition. Patients with heart failure and kidney failure must strictly adhere to water levels from doctors.
Notes for posture hypotension
Drinking 300-500ml of water quickly can cause temporary high blood pressure when you have dizziness due to sudden changes in posture.
Do not abuse this tip. Dizziness may be due to medication or cardiovascular disease. Have a doctor examine you to find the root cause instead of forcing yourself to drink plenty of water.
Special notes for posture hypotension
In contrast to high blood pressure, some people face dizziness and lightheadedness when suddenly standing up due to posture hypotension. In cases of autonomic nervous disorders, quickly drinking a certain amount of water (about 300-500ml) can create a reaction that temporarily increases blood pressure.
However, this is not a trick that can be applied indiscriminately. Dizziness can stem from many causes such as drug side effects, real cardiovascular disease.

Food advice helps support blood pressure reduction
To control blood pressure, drinking enough water is only a necessary condition. A sufficient condition lies in a specially designed diet to protect blood vessel walls. DASH (Dietary Approaches to Stop Hypertension) diet with food groups you should prioritize:
Dark green leafy vegetables: Kale, spinach, romaine lettuce are rich in potassium. Potassium acts as an "antidote" to sodium, helping the body excrete excess salt through urine and dilate blood vessel walls.
Berries: Blueberries, raspberries, strawberries are rich in flavonoids, a powerful antioxidant compound that helps prevent atherosclerosis and supports blood pressure reduction.
Fatty fish: Salmon, herring, mackerel provide a high-quality source of Omega-3, which helps reduce inflammation, lower triglycerides and protect the blood vessel system.
Oats and whole grains: Contain a large amount of soluble fiber, which helps control bad cholesterol and reduce pressure on blood flow.

Question and answer corner: Does dehydration change blood pressure?
Why can dehydration affect blood pressure? Answer: When the body is dehydrated, circulatory volume decreases. To ensure that enough blood is pumped to the organs, the body will automatically activate regulating mechanisms including increased heart rate and vasoconstriction. This change in blood vessel tone causes blood pressure to fluctuate. The level of change depends on the degree of dehydration, age and types of medication the patient is taking.
