Drinking water on an empty stomach is a common health practice, and it can be beneficial in some ways—but many online claims about it are exaggerated.
Possible benefits of drinking water after waking up:
- 💧 Rehydrates the body: You lose water overnight through breathing and sweating, so a glass of water can help restore fluids.
- 🚽 May support regular bowel movements: Staying well hydrated can help prevent constipation for some people.
- ⚡ May help you feel more alert: Even mild dehydration can contribute to tiredness or difficulty concentrating.
However, there is no strong scientific evidence that drinking water on an empty stomach “detoxes” the body, melts fat, cures diseases, or provides special benefits that you wouldn’t get from drinking water at other times of the day.
