How Much Water Between Iftar and Sehri? A Simple Schedule
The short answer: most healthy adults do well with about 8 to 10 glasses (roughly 2 to 2.5 litres) between iftar and sehri, spread in small slots across the evening and night, not gulped in one go at sehri. People with kidney or heart disease follow the fluid limit their doctor sets, not this schedule.
Before you start
- Target: about 8 to 10 glasses of 250 ml each, more on hot or sweaty days.
- How: 1 to 2 glasses per slot, 5 or 6 slots from iftar to sehri.
- What counts fully: water, milk, lassi, thin daal, soups, water-rich fruit.
- What counts a little: chai, coffee and cola, because of caffeine and sugar.
- Fluid limits: kidney and heart patients follow their doctor’s number.

How much water between iftar and sehri is one of the most-searched Ramzan questions, and for good reason. You get only a few hours to put back what a whole day took out. The usual pattern (a huge glass at iftar, then nothing much, then a panicked litre at sehri) doesn’t work well. Below is a simple timetable you can follow tonight. It’s part of our Ramzan Health series.
Why gulping at sehri doesn’t keep you hydrated
Your kidneys are like a careful shopkeeper. When a flood of water arrives all at once they don’t store the extra, they send it out, so a litre drunk in five minutes at sehri mostly leaves as urine within a couple of hours, often before you’ve even finished Fajr. It sloshes. Heartburn follows.
Sips are different, because the body has time to take each one up into the blood and tissues before the next arrives, so far less spills straight out as urine. That’s the whole idea.
Did you know? Food supplies a real share of your daily water. A plate with cucumber, tomato, dahi and a bowl of daal can add the equivalent of a glass or two without you drinking anything.
A simple iftar-to-sehri water schedule
This assumes iftar around 7 pm and sehri around 3:30 am. Slide the times to match your city.
| Time | Slot | Glasses |
|---|---|---|
| Iftar (about 7:00) | Open with water and a date or two | 1 to 2 |
| After Maghrib and the meal (7:45) | Water or lassi with food, not a huge amount | 1 |
| Before taraweeh (8:30) | Water | 1 to 2 |
| After taraweeh (10:30) | Water, milk or a small sharbat | 2 |
| Before sleep (11:30) | Water, sipped | 1 |
| Sehri (3:30) | Water plus water-rich food | 1 to 2 |
Add these up and you land between 7 and 10 glasses. On a hot day or after sweaty work, aim for the top of each range. Keep it simple: use one marked bottle (a 1.5 litre bottle filled once in the evening and topped up once) so you’re not counting glasses in your head.
If you miss a slot
No big catch-up gulp. Just add half a glass to each of the next two slots. If you sleep through sehri, the fast will be harder, so keep the next day gentle and skip heavy outdoor work if you can.
The busy-person version
Three anchors only: two glasses at iftar, two to three glasses after taraweeh, two glasses at sehri. Keep a filled bottle by your bed and one at the prayer mat. It’s not perfect. It’s far better than nothing.
Chai, cola and sharbat: do they count?
Everything wet counts. Not equally.
- Chai and coffee: the water in them counts, but caffeine makes you pass a bit more urine and can stir up thirst the next day. One or two cups after iftar is fine. Three cups at sehri is a thirsty afternoon waiting to happen.
- Cola and packaged juice: lots of sugar, and cola adds caffeine too. They quench thirst for a moment, then leave you wanting more.
- Sharbat: a small glass is a pleasant tradition. Watch the sugar; the Rooh Afza portions guide shows how quickly it adds up.
- Milk, lassi and thin daal: count well and bring salt and protein, which help the body hold water.
Plain water carries the load; everything else is a side dish.
Salt, food and the thirst you feel next day
How thirsty you feel at 2 pm tomorrow depends a lot on sehri tonight, because salty food pulls water out of your cells and the brain reads that pull as thirst, hours later, when there’s nothing you can do about it. Pakoras at iftar are part of the fun; pickles, namkeen and extra-salty parathas at sehri are the real problem. The what to eat for sehri guide has plates that keep you fuller and less thirsty.
Water-rich foods help quietly: cucumber, tomato, watermelon, melon, oranges, dahi, soups and salan with gravy.
If you have kidney disease, heart failure or liver disease, your doctor may have set a fluid limit, sometimes well under 8 glasses. That number wins, fasting or not. People on water pills (diuretics) or with swelling in the legs should ask their doctor about fluids and medicine timing before Ramzan; don’t change the timing on your own. Anyone with diabetes should check sugar if unusually thirsty, and break the fast if it reads under 70 or over 300 mg/dL. Pregnant and breastfeeding women need more fluid, and whether to fast is a question for their doctor and scholar together.
How to tell if you drank enough
By mid-evening, after a few slots, your urine should be pale yellow. If it’s still dark at bedtime, drink a little more in the next slots. In the afternoon of the fast, clear yellow is fine and dark yellow means tomorrow evening needs more. High blood sugar causes thirst too, so if you have diabetes, roza with diabetes lists the questions to take to your doctor.
Questions people ask about water in Ramzan
How much water should be drunk between iftar and sehri?
About 8 to 10 glasses (around 2 to 2.5 litres) for most healthy adults, more in heat or after sweaty work. Spread it over 5 or 6 slots rather than drinking it all at once.
Is drinking a lot of water at sehri good?
Not in one go. A big gulp mostly leaves as urine before midday and can cause heartburn. One or two glasses at sehri, with the rest spread through the night, works better.
Does tea count as water intake in Ramadan?
Partly. The water counts, but caffeine increases urine a little and can make the next day thirstier. Keep chai to one or two cups after iftar.
What is the best drink for sehri to avoid thirst?
Plain water, plus milk or lassi if you like it. Avoid salty food and heavy caffeine at sehri, as both make thirst worse by afternoon.
How can thirst be avoided during a roza?
Spread water across the evening, eat water-rich foods, go easy on salt at sehri, cut chai slowly before Ramzan and stay out of the midday sun where you can.
Can kidney patients drink 8 glasses of water in Ramadan?
Only if their doctor agrees. Some kidney patients have a strict fluid limit, and fasting itself may not be safe for them. Ask the doctor before Ramzan.
Is cold water at iftar bad for the stomach?
No, cool water is fine for most people. Sip it slowly rather than gulping a large cold glass on an empty stomach, which can cause cramping in some people.
Does eating watermelon at sehri help with thirst?
It helps a little, since watermelon is mostly water. Pair it with protein and fibre so you also stay full.
How much water is too much at night in Ramzan?
Very large amounts in a short time, several litres in an hour or two, can dilute blood salt and cause headache, nausea and confusion. Spread intake out and you won’t come near that.
