Raging thirst

We need to drink roughly 1-2 ltr of water during the day to stay hydrated over a 24-hour period. Check the colour of your urine at bedtime. It should be a very pale yellow – anything darker means you haven’t had enough liquid.

✱ FIX IT

Stay hydrated, avoid salty foods and switch the central heating off before bedtime. If your thirst can’t be quenched with a drink, see your GP – it could be a sign of diabetes.
