What percentage body mass loss defines severe hypohydration?

Explanation:
Severe dehydration is defined by a loss of body mass due to fluid loss that exceeds 5%. In exercise, small losses (around 1-2%) don’t cause major issues, and moderate dehydration (about 2-5%) can impair performance and thermoregulation. But once fluid loss goes past 5%, the risks to circulation, heat management, and overall health rise significantly, which is why this threshold is used to define severe hypohydration. The other ranges describe milder dehydration, while the threshold statement covers all cases above 5%, making it the most accurate descriptor.
