Timing of water intake may affect blood pressure in orthostatic hypotension

This study looks at whether drinking 16 ounces of water raises blood pressure more in the morning or the afternoon in people with orthostatic hypotension (a condition where blood pressure drops when standing). Twenty participants will drink water at two different times of day, and researchers will measure their blood pressure and heart rate for an hour after each drink. The goal is to understand if there is a daily rhythm in how the body responds to water.
