To prevent migraines, drink more water

For migraine sufferers, summer can be a perilous time of year.

Oppressive heat and spikes in temperature have long been thought to precipitate attacks in people prone to chronic headaches. One large study in the journal Neurology even showed that the risk of migraines jumps nearly 8 percent for every 9-degree rise in temperature.

But a simple step that may lower the risk, especially in warm weather, is to stay properly hydrated. Dehydration causes blood volume to drop, researchers say, resulting in less blood and oxygen flow to the brain and dilated blood vessels. Some experts suspect that a loss of electrolytes causes nerves in the brain to produce pain signals.

Anyone who has ever woken up dehydrated after a night of heavy drinking knows this feeling as a hangover. But migraine sufferers may be more sensitive to the effects of dehydration.
