Feeling dizzy when you stand up? Simple muscle techniques can effectively manage symptoms

by Elsevier Investigators determined both lower body muscle preactivation (PREACT) and lower body muscle tensing (TENSE) effectively reduced the drop in mean arterial pressure upon standing and improved symptoms of initial orthostatic hypotension. Left: Schematic diagram of the three interventions: no intervention (Control), PREACT, and TENSE. Right: Drop in mean arterial pressure following Control (blue),...
