Hot Weather Tip
Misconception: You need to drink even when you’re not thirsty
For a long time, common wisdom among sports and fitness types held that if you become thirsty it was ‘too late’ – you were already suffering the effects of dehydration.
Consequently it was best to drink continually during exercise.
Now, some beleive that distrusting your thirst in this way could even lead to drinking too much.
In truth, hydration needs will vary from person to person, and the best advice now seems to be "drink when you’re thirsty".
It’s easy to underestimate the amount of water you need especially in hot weather.
It’s prudent to take more water than you think you might need.
As a guide, for the average person three litres or more is often not excessive for a big day in the hills.
