Ever wondered why drinking alcohol tends to give you a headache the next day? It’s because drinking causes the body to become dehydrated, which can lead to the brain swelling so much it produces severe discomfort. The result is a painful headache that won’t subside until your body has had a chance to process the alcohol and become re-hydrated. For those with a tendency to get headaches or migraines, even consuming a little alcohol can present problems.
To help overcome this problem, avoid drinking to excess — in other words, getting intoxicated. Should you feel intoxicated after drinking alcohol, try to consume lots of water, particularly if you’re about to head to bed. This can help the body process the alcohol and may significantly reduce the chances of getting a nasty hangover headache.
