Fasting
Fasting and Ramadan hydration guide
Use the eating window
Split fluid between iftar/evening and suhoor/pre-fast rather than trying to drink everything in one sitting.
Include water-rich foods, normal meals, and some sodium from food unless you have been told to restrict it.
Heat, work, and health conditions
Hot weather, outdoor work, pregnancy, breastfeeding, kidney disease, diabetes, and some medications can change fasting safety and fluid needs.
If fasting causes concerning symptoms or conflicts with medical guidance, talk to a clinician or religious/medical advisor.
Frequently asked
How do I stay hydrated during Ramadan?
Drink steadily between iftar and suhoor, include water-rich foods, limit excessive caffeine, and avoid trying to chug all fluid at once.
Should I use electrolytes while fasting?
They may help after heavy sweat or low food intake, but check first if you have kidney, blood pressure, sodium, potassium, or fluid-restriction concerns.
