Feeling dizzy or light headed can be a minor inconvenience while you are working out or performing tasks around the house, and a serious health risk if you are driving a vehicle. There are a wide variety of reasons that could cause you feel light headed at any point during the day. You may need to make changes in your lifestyle to stop feeling light headed.
Stop any physical activity as soon as you start feeling light headed. This can help to feel better, and also prevent you from injuring yourself.
Lie down so your head is level (no higher or lower) than your heart. As Ask Alice from Columbia University explains, this increases blood flow to the brain, which eliminates the light headed feeling.
Drink plenty of fluids throughout the day. A minimum of six 8-oz. glasses of water a day is recommended, and this amount should be increased whenever you work out or engage in any other harsh physical activity.
Eat six small meals a day. Keeping food in you throughout the day prevents blood sugar from dropping too low, which could make you feel light headed.
Limit or remove stimulants, such as refined sugars or caffeine, or drugs, such as alcohol, from your diet. Any of these can make you feel dizzy or light headed.
Speak with a psychiatrist. Feeling light headed may be caused by stress and anxiety, and therapy may help you deal with these issues. A psychiatrist can prescribe a medication to help avoid feeling light headed.
