Kids are always getting stomachaches and rashes. But headaches? Strictly for grown-ups, right?

Wrong. The majority of school-age children get headaches, and many have headaches on a recurrent basis. Even before entering school, roughly one-third of children experience a headache at some point.You know the pain is real, but what can you do? Find out what's triggering your child's head pain and identify measures you can take to help.What causes children's headaches?A number of factors, singly or in combination, can make your child headache-prone. These factors include:Genetic predisposition. Headaches, particularly migraines, tend to run in families. If you have a family history of bad headaches, your child will have a higher risk of getting them too. Head trauma. Accidental bumps and bruises can cause headaches. Although most head injuries are minor, seek medical attention right away if your child falls hard on his or her head. Also contact a doctor if your child has a steadily worsening headache after a bang on the head. Illness and infection. Headache is a frequent symptom of many common childhood illnesses. Ear infections, sinus infections, colds and flu are often accompanied by headache. Environmental factors. Conditions in the environment, including weather changes, odors, loud noises and bright light all can cause headaches. Emotional factors. Peer pressure, school problems and parental expectations can lead to high levels of stress and anxiety. Children with depression may complain of headaches, particularly if they have trouble recognizing feelings of sadness and loneliness. Certain foods and beverages. The food additive monosodium glutamate (MSG), found in such foods as bacon, bologna and hot dogs, has been known to trigger headaches. Also, caffeine, which is in soda, chocolate, coffee and tea, can cause headaches. Sleep deprivation. Overtiredness may cause headaches in children. Inadequate hydration. Lack of fluids can also cause headaches.What kind of headache does your child have?Headaches are typically hard to describe, especially for children.
