A safe homemade oral rehydration drink follows the standard formula of 1 liter (about 4 cups) of clean or boiled-then-cooled water mixed with 6 level teaspoons of sugar and half a level teaspoon of salt, stirred until fully dissolved. Precise measuring matters, because too much sugar can worsen diarrhea and too much salt can be dangerous, especially for infants, young children, older adults, and anyone with kidney or heart conditions. Sip small amounts frequently rather than drinking large volumes at once, discard any unused mixture after 24 hours, and avoid soda, juice, or sports drinks as substitutes. There are several important safety factors, warning signs of severe dehydration, and age-specific adjustments to consider, so see below to understand more before you mix or give this drink.
If you are dealing with vomiting, diarrhea, dizziness, or dark urine, homemade rehydration fluid is only part of the picture, and knowing when home care is enough versus when you need urgent medical attention can make a real difference. A free, instant, online symptom check takes just a few minutes, asks the same kinds of questions a clinician would, and helps you understand what your symptoms may point to and what steps to take next.

Dehydration—from diarrhea, vomiting, fever or excessive sweating—can quickly lead to serious health problems if not treated. An oral rehydration solution (ORS) restores vital fluids and electrolytes with a simple, proven recipe recommended by the World Health Organization (WHO). This guide explains how to prepare a safe, effective homemade ORS, using clear language and bullet points for easy reference.

This oral rehydration solution recipe safe method ensures you get a balanced, life-saving drink without unwanted side effects.
Tip: Use measuring spoons rather than pinches or shakes to get consistent results.
Wash hands and utensils.
Always start with clean hands, a clean mixing bowl or pitcher, and a clean spoon.
Measure the water.
Pour 1 liter of safe water into your container.
Add sugar.
Stir in 6 level teaspoons (30 g) of table sugar until it dissolves fully.
Add salt.
Stir in ½ level teaspoon (2.5 g) of salt until the solution is clear.
Taste-test (optional).
The solution should taste slightly sweet and not too salty. If it tastes too salty, add a little more sugar or more water to dilute.
Store safely.
Keep the ORS covered. Use within 24 hours—discard any unused solution after that.
Homemade ORS is appropriate for treating mild to moderate dehydration in adults and children, such as:
Administer small sips every few minutes. For infants, offer ORS with a dropper or small spoon.
Homemade ORS can support mild cases, but immediate medical attention is needed if you or a loved one experiences:
For anything that could be life-threatening or serious, always speak to a doctor promptly.
