Simple test can tell you if you're dehydrated - before you even feel thirsty

One common misconception is that the only sign of dehydration is thirst - however, there are other ways to determine whether you're dehydrated before it gets to such a severe stage. Dr Myro Figura, an anaesthetist and medical educator, demonstrated a simple test often performed in hospitals which can be done just about anywhere.

In his video demonstration, he advises to check your hydration level by pinching your skin. If your skin returns to normal almost instantly, you're well hydrated.

However, if the 'pinched' skin maintains its shape even after your finger is removed, it suggests that you need to increase your water intake. In explanation, Dr Figura said: "When you're dehydrated your extra cellular space contracts and that reduces your skin elasticity."

"When you pinch your skin like this, it'll stay up if you're dehydrated. The only problem with this video is you're supposed to do this test on the back of the hand, not on the digit."

This test, known as the Turgor pinch test, can also be performed on other parts of the body. This includes the abdomen or under the collarbone on the chest front, reports Gloucestershire Live.

Drinking fluids regularly is key to managing and preventing dehydration. Ideal choices include water or diluted squash.

There are additional clues to detect dehydration in yourself and others. The NHS website lists these symptoms of dehydration in adults and children:

• feeling thirsty

• dark yellow, strong-smelling pee

• peeing less often than usual

• feeling dizzy or lightheaded

• feeling tired

• a dry mouth, lips and tongue

• sunken eyes

Babies may exhibit slightly different but not entirely dissimilar signs of dehydration. These include:

• a sunken soft spot (fontanelle) on top of their head

• sunken eyes

• few or no tears when they cry

• not having many wet nappies

• being drowsy or irritable

If you're experiencing symptoms of dehydration, it's crucial to consume fluids. If you're feeling nauseous or have vomited, drinking might be challenging, so begin with small sips and gradually increase your intake.

If you're vomiting or suffering from diarrhoea and losing excessive fluids, it's important to replenish the sugar, salts, and minerals your body has lost. A pharmacist can suggest oral rehydration solutions like powders that you mix with water and then consume.
