Hydration without guesswork

Drink with a plan.

Fluid needs change with duration, intensity, climate and individual sweat rate. A useful strategy starts with observation rather than a fixed universal amount.

Your Nutrition JournalUnderstand before deciding.
01

Start well hydrated

Regular daily drinking is the foundation.

02

Adapt to the session

Heat, duration and sweat rate change the need.

03

Avoid extremes

Both too little and excessive drinking can be harmful.

01
Before training

Everyday hydration is the starting point.

A good plan does not begin five minutes before exercise. Regular fluid intake across the day makes last-minute overdrinking unnecessary.

Urine colour and thirst can offer rough orientation but are not precise diagnostic tools.

  • Drink regularly through the day
  • Include meals and water-rich foods
  • Adjust gradually in hot conditions
02
During exercise

The session determines the strategy.

A short easy workout usually needs a different approach from a long event in heat. Body size, clothing, pace and personal sweat rate all matter.

Comparing body mass before and after representative training can help estimate individual fluid loss when done sensibly.

  • Practise the plan in training
  • Use familiar and tolerated drinks
  • Do not force large amounts without need
03
After exercise

Replace losses calmly, not all at once.

Fluids, meals and recovery belong together after a demanding session. Sodium and carbohydrate may matter in longer or very sweaty sessions.

Persistent dizziness, confusion, vomiting or severe headache require medical attention rather than another sports drink.

  • Combine drinking with the recovery meal
  • Observe individual tolerance
  • Seek medical help for severe symptoms
A quick reality check

Myth and reality.

Myth

“More water is always better during sport.”

Reality

Drinking far beyond losses can also be dangerous. The goal is an individual, practised middle ground.
