(FoxNews) - Wondering why you always get a headache the morning after drinking wine? Many people think that sulfites are the culprit behind wine headaches, but other chemicals are likely to blame. Some studies suggest that a naturally occurring substance in wine called tyramine may cause headaches, possibly due to the way it affects blood pressure. Wine, especially red wine, can also contain histamines, which some people can't metabolize.

Taking a non-drowsy antihistamine prior to drinking wine may help. Research has also shown that the tannins in wine may boost production of the brain chemical serotonin, and changes in serotonin levels can trigger headaches in migraine sufferers. You may want to try switching to white, given that most of the tannins are found in the skin and seeds of the grape. (In white wine, the skin and seeds are removed during production.) Or, if you really love red, see if you find relief by sipping a lighter-bodied variety, like pinot noir, which will have lower levels of tannins.
