Let’s be real: sometimes the barf monster wins. If you’re already vomiting or you have a stomach bug, ice water might just come right back up. In that case, freeze pops or ice cubes to suck on are your better bet. They hit the same cold spot but are slower and less likely to trigger a revolt.
If your nausea lasts more than a day, or you can’t keep any liquid down, please call a doctor. Ice water is a helper, not a miracle worker. But for the everyday “ugh, I ate too much cake” nausea? It’s a rockstar.
