Why do hangovers happen




















Fact: While this might temporarily minimize some symptoms, it could contribute to and prolong the malaise and other symptoms of the hangover. Although many remedies for alleviating hangovers are mentioned on the web and in social media, none have been scientifically proven to be effective. There is no magic potion for beating hangovers—and only time can help. A person must wait for the body to finish clearing the toxic byproducts of alcohol metabolism, to rehydrate, to heal irritated tissue, and to restore immune and brain activity to normal.

Some people take over-the-counter pain relievers often acetaminophen before going to bed to minimize hangovers. It is important to recognize that the combination of alcohol and acetaminophen can be toxic to the liver. Like alcohol, certain over-the-counter pain relievers, including aspirin and ibuprofen, can increase acid release and irritate the lining of the stomach. Proceed with caution when using these medications before or after consuming alcohol. To help ease their hangover symptoms, some people turn to electrolyte-rich sports drinks or other products, or even intravenous IV treatments, in an effort to treat electrolyte imbalance caused by increased urination and fluid loss as a result of drinking.

Research has not found a correlation between the extent of electrolyte disruptions and the severity of hangovers, or the impact of added electrolytes on hangover severity. In most people, the body will quickly restore electrolyte balance once the effects of alcohol subside. Ultimately, the only surefire remedy for a hangover is to avoid getting one by drinking in moderation or choosing not to drink.

The main cause of a hangover is the effect of ethanol — the alcohol in your drinks. It's a toxic chemical that works in the body as a diuretic, which means it makes you pee more and you can become dehydrated as a result.

To avoid recurrence of hangovers, keep track of what you're drinking and stay within the low risk drinking guidelines by not regularly drink more than 14 units of alcohol per week.

If you do choose to drink as much as this, spread your drinking evenly over three or more days and take several drink-free days during the week.
