Rest and hydration are potential remedies for dizziness, according to WebMD. These remedies are ideal if the dizziness occurs while suffering from a cold or the flu.
Lying down allows more blood to circulate to the brain, decreasing feelings of dizziness. WebMD advises that following rest, it is important to rise slowly. Get plenty of fluids, particularly water, as well. This is especially important for anyone suffering from flu and cold symptoms. Individuals should avoid caffeine, alcohol, tobacco and illegal drugs when dizziness occurs, according to WebMD, as these products further inhibit circulation. Prolonged dizziness that occurs along with an irregular heartbeat or fainting likely calls for medical attention.
