Children sometimes make themselves dizzy by spinning around in circles or by holding their breath.
Most of these games are perfectly harmless. Another common cause of dizziness in children is postural hypotension. Postural hypotension is the feeling of lightheadedness your child gets if he or she sits or stands up too quickly. Viral infections such as the common cold or the flu, drug interactions, and stress also can lead to dizzy spells. Consult a physician if lightheadedness persists for more than a few weeks.
