How to test for dehydration?

1

The hand test: This dehydration test is very easy to do. Pinch an area of skin (such as the back of the palm) by lifting it up and then releasing it. If the skin doesn’t return to normal in less than a couple of seconds, instead retains the bump for longer and appears loose, it is a sign that you may be dehydrated.

2

The urine test: If you are hydrated well, your urine will be mostly clear with a tinge of yellow. Darker yellow or orange are the warning colours. If you see those colours, start drinking more fluids and take expert advice.
