Does “Hair of the Dog” Actually Cure Hangovers? The Science

The phrase “hair of the dog” refers to the practice of drinking alcohol to relieve hangover symptoms. The idea is that a small amount of alcohol can alleviate the misery caused by the previous night’s overindulgence. But does it really work, or is it just a temporary distraction?

Scientifically speaking, “hair of the dog” doesn’t *cure* hangovers. A hangover is a complex physiological response involving several factors, including dehydration, electrolyte imbalance, sleep disruption, gastrointestinal issues, and the presence of toxic byproducts of alcohol metabolism, primarily acetaldehyde.

Here’s a breakdown of why it seems to provide temporary relief:

Acetaldehyde Masking

When alcohol is metabolized, it’s first converted into acetaldehyde, a highly toxic compound responsible for many hangover symptoms like nausea, headache, and vomiting. The body eventually breaks down acetaldehyde into acetate, a less harmful substance. When you drink more alcohol the next morning, you essentially flood your system with ethanol, temporarily pausing the breakdown of methanol and slowing down the metabolism of acetaldehyde. This can create a perceived lessening of symptoms because the acetaldehyde that was already present is metabolized slowly, and the creation of more is put off by the new influx of ethanol.

Withdrawal Relief

For individuals who are physically dependent on alcohol, a hangover can be accompanied by mild withdrawal symptoms like anxiety and tremors. A small dose of alcohol can temporarily alleviate these withdrawal symptoms, leading to a perceived improvement in overall well-being. However, this is merely masking the underlying problem and can potentially reinforce unhealthy drinking habits.

Endorphin Release

Alcohol consumption can trigger the release of endorphins, the body’s natural painkillers and mood boosters. This endorphin rush can temporarily mask the pain and discomfort associated with a hangover. However, this effect is short-lived and can be followed by an even worse hangover as the alcohol wears off.

Placebo Effect

The belief that “hair of the dog” will work can also play a role. The placebo effect, where a person experiences a perceived benefit from a treatment that has no actual medicinal value, can contribute to a temporary feeling of relief. Simply believing that the alcohol will help can sometimes make the symptoms seem less severe.

The Downside

While “hair of the dog” might offer fleeting relief, it ultimately prolongs the hangover. You’re essentially delaying the inevitable metabolism of alcohol and its toxic byproducts. Furthermore, it can lead to a vicious cycle of drinking to alleviate hangovers, potentially contributing to alcohol dependence or abuse.

Instead of relying on “hair of the dog,” the best ways to treat a hangover are to rehydrate with water and electrolytes, get plenty of rest, and avoid further alcohol consumption. Pain relievers like ibuprofen can help with headaches, but avoid acetaminophen (Tylenol), as it can be toxic to the liver when combined with alcohol.

In conclusion, “hair of the dog” doesn’t cure hangovers; it only provides temporary relief by masking symptoms and potentially delaying the body’s natural recovery process. A better approach is to focus on hydration, rest, and allowing your body to fully recover.
