B
Sometimes a headache is just a part of another illness, such as a cold, flu or sore throat. When you get better, the headache gets better, too.
If you’re not sick, other activities may also
cause a headache. For example, staying up too late, not eating a meal, or playing in the hot sun too long can cause a headache.
Excitement about a special event or worry about something like a school exam can also cause headaches. Some kids get headaches from riding in a car or bus, or from straining(过度使用) their eyes by spending too much time watching TV or using a computer.
Some foods can cause headaches in some kids, such as bacon, bologna, and hot dogs. The caffeine in sodas, chocolate, coffee, and tea may cause headaches, too. Kids don’t need caffeine, so it’s a good idea to control it in their diet.
Sometimes no one knows why a kid gets headaches, but if you get them, the chances(可能性) are someone in your family gets them, too. The headaches are often inherited. In other words, they run in the family.
