TAKE THE TEST

The easiest way to tell if you’re hydrated is to check your urine, says Phillipa. ‘If it’s dark or has an odour, the problem may be dehydration.’ Check yours with the colour chart (below).

WELL HYDRATED

PALE STRAW:

An ideal colour

YELLOW: You’re OK, but you could do with a small glass of water right now

DARK YELLOW: You may be a little dehydrated. Drink two small glasses of water

VERY LIGHT BROWN: You need to drink about a half-litre of water straight away

LIGHT BROWN: You are dehydrated and may have a headache. Drink a litre of water

POORLY HYDRATED

If your urine is red/dark brown, dehydration may not be the problem. Seek medical advice
