Alcohol causes hangovers and it’s not simple. Drinking affects your body in
several ways. Let’s look into some of the major symptoms of hangovers. To start with, the main signal you receive after getting hit by a hangover is dehydration. Alcohol also reduces the release of the hormone vasopressin. This hormone balances your body’s fluids. Dehydration causes thirst, fatigue, and headaches.
Another major symptom is sleeplessness. While alcohol is a sedative and can promote sleep, hangover symptoms usually interfere with sleep. You may have insomnia as your blood alcohol levels get lower, so you feel fatigued.
