5. Practical suggestions: Scientific drinking water plan at night
1. Establish a "drinking buffer": complete your last drink of water one hour before bed, and then only use a wet cotton swab to moisturize your lips
2. Choose the appropriate water temperature: Warm water around 40°C is less likely to cause nocturia than cold water.
3. Add healthy ingredients: A small amount of lemon juice (no more than 5ml) can help balance electrolytes
4. Use smart cups: Smart water cups equipped with timing functions can effectively control the amount of water you drink at night.
5. Monitor body signals: If your eyelids are swollen or your fingers are tight in the morning, you need to adjust the amount of water you drink the night before.
The latest data shows that about 68% of sleep disorders are related to improper drinking habits. It is recommended to develop a personalized drinking water plan under the guidance of a doctor based on your own situation, and do not blindly follow online rumors.
