There are a number of factors that play a part in whether or not you will get a hangover after a night of drinking. Many of the causes are obvious and most of us know what our own limitations are. It goes without saying that the one true way to avoid a hangover is to avoid or severely limit the amount alcohol you consume.
- The ethanol contained in alcoholic beverages has a dehydrating effect which causes headaches, dry mouth and tiredness. This effect can be lessened by drinking plenty of water before and throughout your night of drinking.
- Your liver breaks ethanol down with the aid of enzymes produced by liver cells. These chemical reactions do many things including impairing the liver’s ability to supply glucose to tissues, in particular to the brain. Glucose is responsible for the brain’s energy and the lack thereof results in fatigue, weakness, moodiness and decreased attention.
- Congeners are the by-products of the process of alcohol fermentation and exaggerate the symptoms of a hangover. The more congeners consumed, the worse a hangover is likely to be. Dark spirits such as brandy, whiskey and red wine contain more congeners than lighter spirits like vodka and white wine. Likewise cheaper spirits have had fewer of these impurities removed and are more likely to cause a hangover.
