It is a common belief that a migraine occurs once the weather changes significantly, and it is absolutely right. Having too high or, vice versa, too low temperatures influence people who suffer from migraines negatively. Usually, the fluctuations in climate are followed by the severe headaches, one of the major symptoms of a migraine. Except for the temperatures, barometric pressures can also predetermine a migraine. A corresponding treatment in advance may be the clue.
