Professor Whiteley noted tea – the nation’s favourite brew – contains caffeine, “which actually causes you to lose water”.
Thus, in addition to coffee and alcohol, tea “can make dehydration worse”.
The main indicators of dehydration include:
- Feeling thirsty
- Dark yellow or strong-smelling urine
- Feeling lightheaded
- A dry mouth.
“Dehydration means your body loses more water than you take in. Without enough water, your body cannot function properly, and you can become unwell,” Professor Whiteley added.
