What do i do if i get light headed a lot?

Hydration and diet: Some people become lightheaded when changing to standing from a sitting or laying position. Move so slowly to let your body adjust to blood moving away from your head. Drinking plenty of fluids and maintaining a well balanced diet are helpful in preventing lightheaded feelings. If you are still noticing these episodes, see your doctor to have the problem investigated further.

See your doctor.: Though lightheadedness might be due to relatively harmless causes like dehydration, there is a chance it could be caused by a heart abnormality or arrhythmia. You should go to see your doctor to get checked out to be sure there is no dangerous underlying cause.

Doctor can evaluate: An normal, healthy person who gets light-headed when getting up from lying or sitting, or who feels faint sometimes, especially on hot days, may have a problem of not enough blood returning to his head fast enough. The blood pressure may be normal or a bit low. After a doctor's exam to rule out medical problems, a person can try taking 3 ounces of extra water each hour, plus a bit of salty snacks.
