The Mayo Clinic tells patients to avoid strong smells that have seemingly started migraines in the past. Some people react badly to products like perfume, even if they have a pleasant smell.

The Clinic's experts say aerobic exercise can help migraine sufferers. Aerobic exercise increases a person's heart rate. It can include walking, swimming or riding a bicycle. But a sudden start to hard exercise can cause headaches. So it is a good idea to perform some mild exercises before beginning activities that require more energy.

The experts advise that people should plan to exercise, eat and sleep at the same times each day.
