According to the National Institutes of Health, water plays an essential role in maintaining blood flow through the kidneys and supporting the filtration process.
When the body is dehydrated, the amount of blood flowing to the kidneys decreases, increasing the risk of kidney stones and reduced filtration function.
Similarly, the World Health Organization also emphasizes that maintaining sufficient water is one of the most important factors to help the excretory system function effectively, especially in hot and humid climates.
Filtered water
Although there are many types of cooling water, filtered water is still the optimal choice. Drinking enough 1.5-2.5 liters of water per day helps increase urine output, thereby supporting the elimination of residues such as urea, creatinine and uric acid.
Studies show that drinking enough water also helps reduce the risk of kidney stones - a common problem in hot weather.
Coconut water
Coconut water contains potassium, magnesium and natural electrolytes, which help rehydrate effectively after dehydration due to sweat. According to some studies, coconut water can help reduce the risk of kidney stones crystallizing.
However, it should be noted that the high potassium content in coconut water may not be suitable for people with chronic kidney disease.
Lemonade
Lemon juice is rich in citrate - a compound that can inhibit the formation of calcium crystals in the kidneys. According to documents from the National Institutes of Health, citrate can help reduce the risk of kidney stones when supplemented with food.
Vitamin C in lemon also helps boost the immune system and fight oxidation.
Herbal tea
Teas such as chamomile tea, peppermint tea or ginger tea provide flavonoids and polyphenols, which help reduce oxidative stress, a factor related to kidney damage.
These drinks also have mild diuretic effects, supporting waste removal.
Bean water
Waters such as black beans and green beans provide plant protein, fiber and antioxidants. These nutrients help improve metabolism and reduce the burden on the kidneys.
Note, do not completely replace filtered water with fresh water or herbal water;
Limit sugary drinks as they can increase the risk of metabolic diseases;
Kidney patients need to control their potassium and water levels according to doctor's instructions...
