Sun Exposure Linked to Red Wine Headaches

A new study from the University of California suggests that headaches caused by red wine may be linked to a compound called quercetin found in red grape skins. Quercetin, an antioxidant, may disrupt how we metabolize alcohol, leading to toxic buildup and headaches. The study also found that increased exposure of red grapes to sunlight results in higher quercetin levels, particularly in Cabernet wines from sunny regions like Napa Valley. However, other factors such as additives, allergies, and preservatives in wine are also being considered as potential causes of headaches. Researchers hope to identify which wine varieties cause better reactions in order to provide relief for those affected.
