If someone suddenly feels light-headed and might faint (or when you feel that way yourself), there are two steps you can take to help. “First, get them lying down-not just sitting, but fully horizontal,” says Eunice Singletary, M.D., a member of the American Red Cross Scientific Advisory Council and a clinical associate professor of emergency medicine at the University of Virginia Health System in Charlottesville, Va. “otherwise,” she says, “they are at risk of falling” and getting hurt.
Next, try a technique called a “physical counter pressure maneuver.” Instruct the person feeling faint to squeeze her hands together or cross her legs and squeeze her thighs tightly. This muscle contraction “helps push the blood back into the brain, raising the blood pressure and in many cases improving the symptom of feeling light-headed,” Singletary says.
When a person has chest pain or difficulty breathing along with light-headedness, the technique should not be used. Call 911 immediately, Singletary advises.
