Urine is a salty substance {though less so than the NASA Ames chili}, and if you were to drink it in an effort to rehydrate yourself, it would have the opposite effect.
In her book "Packing for Mars: The Curious Science of Life in the Void," author Mary Roach discusses the composition of urine, highlighting its salty nature. She emphasizes that, despite common misconceptions, consuming urine as a means to rehydrate can actually lead to dehydration rather than relief.
This counterintuitive fact underscores the need for proper hydration methods, especially in space and extreme conditions. Roach’s insights serve as a reminder that even well-intentioned actions, like drinking urine, can have adverse effects on the body due to its saline content.
