headaches are sometimes caused by temperature changes (going inside a cold room then going outside where it is hot), sometimes it is caused when you think too much and can't solve something you want...., and if you have colds (blowing your nose too hard)

Headaches can be caused by dehydration- so you need to drink water to cure it.. headaches are completely normal, as long as they are not like migranes- which are extremely intense :(
