yolo # 10 : Reasons for Hangover

The moment you drink, your liver works, and when ethanol comes in, your liver breaks down ethanol into acetaldehyde using ADH (Alsoal dehydrogenase).

Acetaldehyde is decomposed into acetic acid by ALDH (acetaldehyde dehydrogenase) and then released out of the body.

We have a lower ALDH ability to break down acetaldehyde than Westerners, so acetaldehyde remains in our ability to break down acetaldehyde.

Acetaldehyde is a toxic substance and carcinogen, which causes various side effects and a hangover while in the body.
