You're Probably not Dehydrated: The Eight Glasses of Water a Day Myth

The video debunks common myths about dehydration and the need for excessive water intake. It highlights that real dehydration is rare among healthy individuals and that the body signals thirst before dehydration occurs. Scientific studies show no significant health benefits from drinking extra water, except in specific cases like preventing kidney stones. The video also critiques the use of urine osmolality as a measure of dehydration in children, suggesting that the definition may be flawed. Despite media and advertising claims, there is no formal recommendation for daily water intake, and most people get sufficient hydration from various sources.
