Liquid and electrolytes

Water and Electrolytes and training: practical explanations, risks, and actionable tips.

How much water do you need during exercise?

There's no universal amount of water everyone should drink during exercise. The amount needed is determined by how much a person loses through sweat, which depends on the intensity of the exercise, temperature and humidity, clothing, body weight, fitness level, and individual sweat rate.

Should I drink water immediately after waking up?

No, there's no medical need to drink water immediately after waking up. If you're thirsty in the morning, a glass of water is a simple and beneficial way to begin replenishing fluids after several hours without drinking.

When do you really need electrolyte drinks?

Electrolyte drinks are not needed for everyday drinking, but primarily when a person loses a significant amount of water and salts: during prolonged intense physical activity, several hours of profuse sweating in the heat, as well as during significant diarrhea or vomiting.

What are electrolytes and why do the body need them?

Electrolytes are substances found in body fluids as electrically charged particles called ions. The main electrolytes include sodium, potassium, chloride, bicarbonate, calcium, magnesium, and phosphate.

Does the average person need electrolytes and when should they be taken?

Most healthy people don't need to take electrolytes every day. The body obtains sodium, potassium, magnesium, calcium, chlorides, and phosphates from regular food and beverages, and the kidneys, along with the hormonal system, maintain their concentrations within fairly narrow limits.
