Ethanol may cause headaches by several means. Excess consumption of ethanol may produce dehydration and chemical imbalances in the body. These chemicals are called congeners.
Congeners impart the specific tastes and flavors that make each beverage unique.
These congeners also have a variety of effects that can cause headaches and alter other chemicals in the body, which if consumed in excess may cause the hangover effect. Fructose, the naturally occurring sugar from fruits helps return portions of the body's chemical balance back to normal following ethanol consumption. All rights reserved.
