Thirst during Ramadan can affect the body even when it is full of water. This is what medical studies from Andalusia Hospital indicate: the body may remain thirsty and cells may become dehydrated even when drinking large amounts of water if the body does not absorb enough sodium and potassium.
Why is water alone not enough to prevent thirst during Ramadan?
Avoiding thirst during Ramadan, and even on regular days, requires balancing the body between drinking enough water and consuming foods rich in nutrients and hydrating elements such as sodium and potassium.
During Ramadan and long fasting periods, the body needs to retain fluids to prevent dehydration and avoid excessive thirst. [1]
Does drinking too much water prevent thirst?
No. There is a difference between drinking enough water to maintain fluid balance and drinking excessive amounts without replenishing sodium and potassium. Drinking too much water may increase bathroom visits, which reduces body fluids and increases thirst instead of preventing it.
I also want to remind you that excessive water loss through urination increases the risk of low blood sodium levels, sometimes to dangerous levels, so you should be careful. [2]
Best foods that prevent thirst during Ramadan
Hydrating the body during Ramadan comes from eating foods rich in fluids and water, especially during suhoor. The most recommended foods include: [3]
Water-rich fruits and vegetables: Watermelon, cucumber, citrus fruits such as oranges and grapefruit, tomatoes, and celery.
Dairy products and yogurt: They provide high hydration and help reduce the feeling of thirst.
Fiber-rich foods: Oats, whole grains, leafy vegetables, and dates, as they slow digestion and help maintain body hydration.
Potassium-rich foods: Bananas and nuts, which help maintain fluid balance.
Mistakes that cause thirst during Ramadan
One of the main causes of thirst during fasting is practicing some wrong habits, especially when repeated daily, as they can increase thirst day after day. You should also pay attention to the effects of fasting on the skin caused by dehydration resulting from continuous thirst. [4]
The most common mistakes that cause thirst include:
Too much salt
Eating foods high in salt, such as processed meats, pickles, salty cheese, and canned foods, can cause thirst throughout the day.
Excessive caffeine intake
Drinking large amounts of coffee, tea, instant coffee, or even soft drinks, especially at suhoor, increases bathroom visits because caffeine acts as a diuretic. This causes the body to lose more fluids and leads to thirst.
Drinking too much water at once
The body gets rid of excess water quickly when large amounts are consumed at once, which makes the body lose hydration faster.
Eating spicy and fatty foods
Spicy and fatty foods increase indigestion and make the body need more water, which increases the feeling of thirst.
Skipping suhoor or eating it too early
Skipping suhoor or eating it too early before Fajr increases the duration of body dryness because it extends the fasting hours.
Eating foods high in sugar
Eating sweets and sugary drinks, especially at iftar, causes rapid fluctuations in blood sugar levels, which increases thirst.
Potassium deficiency
Not eating enough potassium-rich foods, such as bananas, may reduce the body’s ability to retain water.
Conclusion
Avoiding thirst during Ramadan requires reducing caffeine, sugar, excessive salt, spicy foods, and fatty foods, while increasing potassium-rich foods. Drinking water alone does not prevent thirst. In fact, drinking too much water at once may increase fluid loss from the body, leading to dehydration and thirst during fasting.
