What is a hangover?

• A. A temporary increase in energy after only one drink.

• C. The aftereffects of drinking too much alcohol, including nausea, upset stomach, headache, and sensitivity to noise.
• D. A sign that the liver has fully detoxified.

Answer: (C)

Hangover is the aftereffects that follow drinking too much alcohol. It typically includes symptoms like nausea, an upset stomach, headache, and sensitivity to noise. These arise because alcohol dehydrates the body, irritates the stomach, triggers inflammatory responses, and disrupts sleep, with a buildup of byproducts like acetaldehyde as the body processes the alcohol. It’s not a temporary energy boost after one drink, and it’s not a long-term medical condition caused by regular use. It also isn’t a sign that the liver has fully detoxified; rather, the hangover happens while the body is actively clearing alcohol. To avoid it, the best approach is moderating intake, staying hydrated, eating, and getting rest.
