7 Physical activity and fluid intake

Physical activity is important. The more active you are, the more fluid you require. This is because more fluid is lost in sweat and physiological processes. The environmental conditions of this physical activity also have an effect (that is, temperature, humidity and altitude). Swimming can dehydrate you, even though you are surrounded by water!

It is important to be well hydrated before, during (ideally, sip every 20 minutes) and after any activity. Sports drinks may be more beneficial if you exercise for more than an hour.

Activity 7 Fluid intake

Timing: Allow approximately 10 minutes.

So what is more effective at hydrating? Water, of course, or is it? Consider the following questions.

  • What do you tend to drink?
  • What do you feel hydrates more effectively?
  • Are there any drinks that may not be as good for you?
