Did You Know That Drinking Water on an Empty Stomach Could Be Beneficial?
Drinking a glass of water first thing in the morning is a simple habit that many people swear by. While some claims about “water therapy” are exaggerated, staying hydrated after waking up can offer several genuine health benefits. Here’s what the evidence says.
1. Helps Rehydrate Your Body
After 6–8 hours of sleep without drinking, your body wakes up slightly dehydrated. A glass of water helps replace lost fluids and supports normal bodily functions.
2. Supports Healthy Digestion
Water helps move food through your digestive system and can promote regular bowel movements. For some people, drinking water in the morning may help stimulate the bowels, especially when combined with a fibre-rich diet.
3. May Help Prevent Constipation
If you don’t drink enough fluids, stools can become hard and difficult to pass. Drinking water regularly throughout the day—including in the morning—can help keep stools softer and easier to pass.
4. Supports Brain Function
Even mild dehydration can affect concentration, alertness, and mood. Rehydrating after waking may help you feel more refreshed and mentally focused.
5. Helps Regulate Body Temperature
Water is essential for maintaining normal body temperature and supports many of the body’s everyday processes, including circulation and sweating.
6. May Help with Weight Management
Drinking water before breakfast may help some people feel fuller, which could reduce how much they eat at the next meal. However, water alone is not a weight-loss solution and works best as part of a balanced diet and regular physical activity.
7. Supports Kidney Function
Adequate hydration helps the kidneys filter waste products and produce urine. Drinking enough water throughout the day supports normal kidney function in healthy individuals.
Common Myths
Some popular claims about drinking water on an empty stomach are not supported by strong scientific evidence. For example, there is no reliable evidence that it:
- “Flushes toxins” from the body beyond your kidneys’ and liver’s normal function.
- Dramatically boosts metabolism.
- Burns fat on its own.
- Cures chronic diseases.
How Much Should You Drink?
There’s no universal rule. For many people, one glass (about 250–500 ml) after waking is comfortable, but your fluid needs depend on factors such as your age, activity level, climate, and overall health.
A Few Tips
- Drink plain water at a comfortable temperature.
- If you enjoy it, add a slice of lemon for flavour—but it’s not necessary for health benefits.
