Heatwave Hydration

2 August 2021

The recent heatwave may have just ended, but the Met Office predicts another will be upon us in late August, and we will surely see more in years to come. Ensuring that patients stay hydrated is vital during these peak temperatures.

For many reasons, patients in hospitals are vulnerable to dehydration, especially during long hot summer days. Particularly vulnerable are the elderly, as they could be totally reliant on ward staff to supply them with enough fluids.

So, how much is ‘enough’ and what kind of drinks count as fluid?

Factors impacting fluid needs

The amount of fluid required depends on several things including age, body temperature, environmental temperature, activity and losses due to vomiting or sickness.

In general, each day, adults need approximately:

Patient holding glass of water
  • Women – 1600ml for example 6 mugs (volume 250ml each) or 8 cups (volume 200ml each).
  • Men – 2000ml for example 8 mugs (volume 250ml each) or 10 cups (volume 200ml each).

On hot days, people lose water through sweating, so the requirement to replace lost fluids goes up. In hot weather, patients should be encouraged to drink more than 6 – 8 mugs of fluid per day.
