    We get headaches sometimes. But how much do you know about headaches? What may cause that? And what should we do if we have a headache? When should we go to see a doctor?

    A headache is not a disease, but it may show that something in our body is wrong. We may have more than one headache each month.

    Usually a fever may cause headaches. We may get a headache when we work too hard. We may get a headache when we don't get enough sleep. We may get a headache when we exercise with an empty stomach. What should we do if we have a headache?

    We should lie down and rest. We should have a good sleep. We shouldn't take too much exercise if we are hungry. If we have headaches often, we need to see a doctor.
