2. Dry skin
Dehydration is not always felt as a dry mouth or extreme thirst but can also reflect in other ways. For instance, well hydrated skin appears doughy while dehydrated skin exhibits a lack of elasticity and resilience. To test if skin is dehydrated, pinch skin and if it appears thin and does not melt back into the body quickly, then you are likely dehydrated.
Dehydrated skin also experiencing flushing since the skin remains mainly dry and is not able to release enough sweat due to the lack of adequate fluid in the body.
