Ayurvedic expert and Patanjali co-founder Acharya Balkrishna is nudging people toward one of the oldest natural drinks this summer: coconut water. In a recent Facebook post, he pointed out that coconut is loaded with vitamins, minerals, and essential nutrients, and that drinking coconut water during hot months helps reduce nausea and excessive thirst. “It is an excellent drink,” he wrote simply.
He’s not wrong. And science backs it up.

Why your body craves it in the heat
When temperatures climb and you sweat through your shirt by 9 am, your body loses more than just water. It loses electrolytes; sodium, potassium, magnesium, the minerals that keep your muscles working and your head clear. Plain water replaces the liquid. Coconut water replaces everything else.
One glass of tender coconut water contains about 600 mg of potassium, more than a banana. That’s why athletes have used it as a natural sports drink for decades. Your heart, kidneys, and muscles all depend on potassium to function properly.
The nausea problem nobody talks about
Summer heatwaves bring a quiet, uncomfortable side effect: nausea. Whether it’s heat exhaustion, dehydration, or an upset stomach from heavy food in humid weather, many people feel queasy without understanding why.
Coconut water has a gentle, cooling effect on the stomach lining. Its natural sugars and electrolytes settle the gut without overwhelming it. Unlike sugary sodas or packaged juices, it doesn’t spike your blood sugar or make things worse. People suffering from mild vomiting or acidity during summers often find relief simply by sipping it slowly.
Not just a thirst quencher
Coconut water does several quiet jobs inside your body that most people don’t know about.
It supports kidney health by acting as a mild diuretic; meaning it encourages urination and helps flush out toxins. This is particularly important in summer when the risk of kidney stones rises because of dehydration.
It also contains cytokinins, plant compounds that have shown anti-ageing and anti-inflammatory properties in research studies. The lauric acid present in it has antibacterial effects. And because it is low in calories (roughly 45-60 per glass), it fits easily into any diet without guilt.
Fresh vs. packaged: there’s a difference
If you’re reaching for a tetra pack of coconut water off a supermarket shelf, pause for a second. Packaged coconut water is often pasteurized, which kills some of its natural enzymes and nutrients. Some brands add preservatives or flavours that are not on Acharya Balkrishna’s or any nutritionist’s approved list.
Fresh tender coconut, cracked open and sipped with a straw, is always the better option. The water from a young, green coconut (roughly 6–9 months old) is the most nutritious; sweeter, richer in electrolytes, and naturally sterile.
When and how to drink it
Morning is the best time. Drinking coconut water on an empty stomach can improve metabolism and give your digestive system a gentle head start. It also works well as a mid-morning drink between 10 AM and noon when heat peaks.
Avoid it at night in large quantities, especially if you have a sensitive bladder, since its diuretic effect can interrupt sleep.
People with kidney disease or those on potassium-restricted diets should check with a doctor before making it a daily habit. Too much potassium is not safe for everyone.
For everyone else, though, one fresh coconut a day this summer is one of the easiest, cheapest, and most natural things you can do for your health. Acharya Balkrishna said it simply. The body knows it instinctively. Trust both.
