Orthostatic hypotension (postural hypotension). This is a sudden drop in blood pressure when standing from a sitting position or after lying down. Causes include dehydration, long-term bed rest, pregnancy, certain medical conditions and some medications. This type of low blood pressure is common in older adults.
If your blood pressure is elevated and you want to see an immediate change, lie down and take deep breaths. This is how you lower your blood pressure within minutes, helping to slow your heart rate and decrease your blood pressure. When you feel stress, hormones are released that constrict your blood vessels.
Something as simple as keeping yourself hydrated by drinking six to eight glasses of water every day improves blood pressure. Water makes up 73% of the human heart,¹ so no other liquid is better at controlling blood pressure.
Call 911 or emergency medical services if your blood pressure is 180/120 mm Hg or greater and you have chest pain, shortness of breath, or symptoms of stroke. Stroke symptoms include numbness or tingling, trouble speaking, or changes in vision.
Lemon drink contains traces of several minerals that may be beneficial in lowering blood pressure. Calcium and potassium both can lower blood pressure in those suffering from hypertension. A study suggests that lemon water can help bring the number to the normal range immediately.
Magnesium intake of 500 mg/d to 1000 mg/d may reduce blood pressure (BP) as much as 5.6/2.8 mm Hg. However, clinical studies have a wide range of BP reduction, with some showing no change in BP.
One study in 48 people with overweight or obesity found that water fasting for an average of 17 days under medical supervision led to reductions in systolic blood pressure ( 15 ). It was also associated with improvements in levels of LDL (bad) cholesterol and inflammation ( 15 ).
Lifestyle Changes
Chronic dehydration also can be a cause of high blood pressure by making the body hold onto sodium. This increases blood volume and thus blood pressure. Make a point of drinking a minimum of eight and preferably 10 to 12 glasses of pure, filtered water every day.
Conclusion: Medically supervised water-only fasting appears to be a safe and effective means of normalizing blood pressure and may assist in motivating health-promoting diet and lifestyle changes.
