Impact of Alcohol on Health

The truth is I can’t tell you exactly how alcohol consumption will impact your health because everyone is different. There are several factors which influence the way alcohol is metabolized in your body including genetics, biological sex, body mass, nutritional status, activity level, and amount/timing of consumption (Barnes, 2014). Here I’ll give you a general overview of the science behind alcohol metabolism and how it affects health.


You probably already knew this one, but one of the most noticeable effects of alcohol is its ability to dehydrate you. Normally, a hormone called anti-diuretic hormone (ADH) helps your body to retain water and keep your cells well-hydrated and functioning properly. However, ethanol, the type of alcohol in drinks, blocks the effects of ADH leading to excess urination and dehydration (Shirreffs and Maughan, 2006).
