What is a common sign of dehydration?

A common sign of dehydration is dark yellow urine. When the body is adequately hydrated, urine should typically be light yellow or clear. However, as dehydration occurs, the concentration of waste products increases in the urine, causing it to take on a darker color due to the higher levels of urobilin, a pigment created from the breakdown of bilirubin.

This darker coloration indicates that the kidneys are conserving water, as the body is experiencing a deficiency in fluid intake. Monitoring urine color is a straightforward and effective way to gauge hydration status, making it important for individuals, especially those engaged in intense physical activity or living in hot climates, to be aware of this sign.

Clear urine usually reflects proper hydration, while frequent urination isn't specifically indicative of dehydration and may occur due to other factors such as fluid intake or certain medical conditions. Increased appetite is generally not associated with dehydration but might stem from a variety of factors including energy expenditure or nutritional needs.
