Drinking water on an empty stomach — especially right after waking up — can be quite beneficial for your body. Here’s a clear breakdown of what it does:

1. Rehydrates your body

After 6–8 hours of sleep, your body is mildly dehydrated. Water first thing in the morning quickly restores hydration levels, which helps your organs and metabolism start functioning efficiently.

2. Helps flush out toxins

During sleep, your body performs repair and cleanup processes. Water in the morning helps your kidneys flush out waste products more effectively.

3. Kick-starts metabolism

Some studies suggest that drinking about 500 ml of water can temporarily boost metabolism by 10–30% for around 30–40 minutes. This is partly because your body needs to warm up the water to body temperature, using energy.

4. Supports digestion

Water prepares your stomach for food by stimulating digestive enzymes and hydrating the gut lining, which can make bowel movements easier.

5. May help with healthy skin

Proper hydration improves blood circulation and helps maintain skin elasticity, which over time can make your skin look healthier.

Tips for best results:

• Drink 300–500 ml (about 1–2 glasses) right after waking up.
• Use room-temperature or lukewarm water — cold water can shock your system early in the morning.
• Wait about 20–30 minutes before eating breakfast for optimal digestion benefits.
