What are the signs of dehydration?

The signs of dehydration include thirst, dry mouth, fatigue, and dark urine, which are all clear indicators that the body is not retaining adequate fluids. Thirst is one of the earliest signals that the body sends when it needs hydration, prompting individuals to drink more water. A dry mouth often accompanies this sensation, as the body reduces saliva production when dehydrated.

Fatigue is another common symptom of dehydration, as reduced fluid levels can lead to decreased energy and overall lethargy. Furthermore, the color of urine is a reliable marker of hydration status; dark urine typically means that the body is conserving water and that urine is more concentrated, indicating dehydration. These signs collectively highlight the body's need for fluid replenishment, making them fundamental indicators of dehydration.
