Does Water Help Flush Out Alcohol from the System?
No. Water does not flush alcohol out of your blood or urine faster: your body has to break alcohol down, and the NIAAA says a person must wait for the body to finish clearing it; only time helps. Water is still useful because alcohol increases urination and fluid loss, and the mild dehydration adds to thirst, fatigue and headache (NIAAA). Coffee, cold showers and walking do not sober you up either.

Can you flush alcohol out with water?
No. Alcohol leaves the body mainly by being broken down (metabolised), not by being rinsed out. The NIAAA explains that after drinking, a person must wait for the body to finish clearing alcohol and its toxic byproducts, and that there is no cure for a hangover other than time. Drinking more water does not speed that up.
Why water still helps
The NIAAA says alcohol suppresses vasopressin, a hormone that signals the kidneys, so alcohol increases urination and fluid loss. The mild dehydration that follows likely contributes to thirst, fatigue and headache. Water or other non-alcoholic drinks help replace that fluid, which can make you feel better, but your blood alcohol level still falls only as fast as your body breaks alcohol down.
Does water flush alcohol out of urine?
Extra water makes urine more dilute, but it does not stop your body from producing alcohol and its breakdown products, and we found no official source showing that drinking water makes an alcohol test negative. Tests such as the PEth blood test measure markers that build up over days or weeks; see our PEth test guide.
What about coffee, sports drinks or a cold shower?
- The NIAAA says cold showers, hot coffee and walking do not reverse an alcohol overdose and could make things worse.
- Electrolyte sports drinks: research has not found a link between electrolyte changes and how bad a hangover is (NIAAA).
When it is an emergency
Call 911 if someone who has been drinking is confused, cannot stay awake, has seizures, slow or irregular breathing, or bluish or pale skin: these are signs of alcohol overdose (NIAAA). Do not leave them alone.
