What continues in the body after the last glass

A long night out doesn't end at the same time for you and your metabolism. While you are long since back home, your body continues to process alcohol and its byproducts.

Breakdown occurs in several stages

Alcohol is primarily broken down in the liver. This process first produces acetaldehyde and subsequently acetate, which can be further processed. The intermediate products and the speed of the breakdown are part of the explanation for why the consequences of drinking extend beyond the evening itself.

The idea that alcohol can be immediately offset by a single food item or supplement is therefore too simplistic.

Fluids, sleep, and the stomach react differently

Alcohol can increase urination, disrupt sleep, and irritate the stomach lining. Thirst, fatigue, and stomach discomfort can therefore have different causes. They cannot all be explained by a single term like "acidification."

Furthermore, the feeling of falling asleep faster says little about the quality of the subsequent recovery.

Why water does not replace alcohol metabolism

Adequate fluid intake is important. However, water does not undo the alcohol previously consumed. Neither does coffee or a cold shower speed up the brain's recovery after alcohol consumption.

There is no evidence that electrolyte products provide a reliable cure for a hangover. The most sensible prevention is to drink less alcohol or none at all.

Acid-base imbalances are a distinct medical issue

Certain severe metabolic situations associated with alcohol can alter the acid-base balance. This cannot be broadly applied to a glass of wine or an ordinary hangover.

If you experience persistent vomiting, confusion, breathing difficulties, or a significant deterioration in your condition, medical help is necessary. You can find more information on normal regulatory pathways under Buffers, Respiration, and Kidneys.
