The text states that thirst occurs at 1% body water loss, more than 5% can cause fainting, and more than 10% can lead to death from dehydration.
The claims regarding the effects of body water loss are supported by varying degrees of medical evidence. The first claim about thirst at 1% water loss is supported by moderate sources discussing cognitive and physical impacts. The second claim about fainting after more than 5% loss is corroborated by medical descriptions of dehydration-related syncope, but doesn't specify the 5% threshold. The third claim about death from more than 10% loss lacks specific supporting evidence in the provided materials.

Physiology
The feeling of thirst occurs when the body loses 1% of its weight in water.
Moderate evidence supports that thirst is triggered when there is approximately a 1% loss of body water, as mentioned in medical reviews. Sources indicate this loss impacts physical and cognitive performance, correlating with the claim.

Health
A loss of more than 5% body weight in water can lead to fainting.
Several medical sources note that dehydration can lead to fainting, though evidence does not specify that 5% water loss is the exact threshold. This makes the claim plausible but not strongly substantiated.

A loss of more than 10% body weight in water can lead to death from dehydration.
General medical consensus holds that significant dehydration can lead to death, but specific sources on the precise 10% threshold are absent from provided evidence, making the claim uncertain.
