The myth of sports drinks persists, but the science is clear: for most workouts, water is sufficient. Only when you sweat intensely for more than an hour, such as during a marathon or strenuous session, does it make sense to replenish electrolytes with these formulas. Otherwise, you are adding unnecessary calories and sugars.
The chemistry of sweat and the hydration algorithm 💧
From a technical standpoint, the human body primarily loses water and electrolytes like sodium and potassium. Sports drinks are designed to optimize intestinal absorption through a specific concentration of carbohydrates (6-8%) and salts. However, in sessions lasting less than 60 minutes, the renal regulation system and body reserves compensate for the loss without issue. Forcing an extra load of sugars only alters glycemic balance and stresses the pancreas without real benefit.
The conspiracy of isotonic marketing 🕵️
Of course, brands spend fortunes convincing you that you need their magic potion to survive a 20-minute walk. The reality is that if you drink water after your routine, your body won't collapse or turn into a salt statue. Most likely, you'll just save money and avoid that liquid caramel flavor that promises performance but tastes like office glue. Drink water; your wallet and your pancreas will thank you.
