Preparing oral rehydration solution (ORS) is a simple and effective way to prevent and treat dehydration, especially when it is caused by diarrhea or vomiting. Here are the specific proportions and steps: ### **Required materials:** - **Clean drinking water**: 1 liter (about 4 cups) - **Sugar**: 6 teaspoons (about 30 grams) - **Salt**: half a teaspoon (about 2.5 grams) ### **Preparation steps:** 1. **Prepare the container**: Make sure to use a clean container and spoon to avoid contamination. 2. **Add water**: Pour 1 liter of clean drinking water into the container. 3. **Add sugar and salt**: Add 6 teaspoons of sugar and half a teaspoon of salt to the water. 4. **Stir thoroughly**: Use a clean spoon or stirring stick to stir the mixture until the sugar and salt are completely dissolved. 5. **Storage**: The prepared oral rehydration salt should be used within 24 hours and should be discarded afterwards. If it needs to be stored for a longer period of time, please keep it sealed and mark the date. ### **Directions:** - **Adults and children**: Drink in moderation according to the degree of dehydration. Generally, you can drink in small sips several times an hour to avoid vomiting. - **Infants**: Use a syringe or measuring cup to ensure accurate dosage. ### **Precautions:** - **Accurate ratio**: Be sure to prepare according to the above ratio to avoid imbalance in the sugar-salt ratio, which may lead to electrolyte imbalance. - **Water safety**: Use clean, boiled or disinfected water to prevent further infection. - **Observe symptoms**: If dehydration symptoms are severe, such as persistent vomiting, inability to eat or drink, and confusion, seek medical attention immediately. - **Storage conditions**: Prepared ORS should be stored at room temperature, away from direct sunlight and high temperature. ### **Warm tips:** Although self-prepared oral rehydration salts are effective in emergency situations, there are also standardized ORS products on the market that contain appropriate amounts of electrolytes and sugars, which are more convenient and safer to use. If conditions permit, it is recommended to choose to purchase certified commercial ORS products. I hope this information is helpful to you and I wish you good health!
