In many gyms, you can order a fresh coconut to hydrate yourself after an intense workout. I had the pleasure to buy a fresh coconut after my runs on the Copacabana in Rio de Janeiro. They had told me that drinking fresh coconut water was a very healthy way to recover from your run.
There is a lot of information on the benefits of coconut water. The last couple of years it has been called out as a superfood and many companies promote coconut water as a healthy drink. Yes, it is a healthy drink compared to all other sports drinks. It is low in calories. With most sports drinks containing dozens of grams of sugar, it would seem that coconut water would be a better option for a carb conscious, high-intensity athlete.
It also contains good nutrients, such as potassium and sodium, so it helps balance electrolytes in the body and that helps you to recover and coconut water aids in hydration. This is especially important after heavy exertion and moderate endurance training. Coconut water also reduces stress. According to a test, the group drinking only coconut water, instead of bottled water or a sweetened sports drink, had the biggest drop in blood pressure.
So yes, coconut water is a healthy drink after your exercise. It is low in calories, high in potassium and reduces blood pressure. But only when it is fresh and not bottled.
