The care plan will tell you:
You need to record in the care plan what an individual has had to drink, how much and the times. This is essential if their fluid intake is being monitored but also it stops workers assuming that the person is not thirsty or has already had a drink. This helps to prevent dehydration and maintain physical wellbeing.

If the weather is hot or a person has been exercising, their fluid intake should be increased.
You need more water when your body temperature rises.
Drinking water helps replenish the fluids lost by excessive sweating. Jumping in cold water is not good enough!
