Moving through the desert in the heat of the day

From BearWiki

Claim: If you're in the desert and low on water, you should move at night, not during the day.

Bear routinely, whenever in a desert environment, travels under the scorching sun in the middle of the day while supposedly desperately low on water supplies. This is a good recipe to end up dead. You lose far less water when it's cool at night than you do during the day, when you should be resting.

[edit] Analysis

Oppose: MAny posonous animals also move at night, and Human eyes aren't as adapted as lets say...snakes, lions, or any other animal. Atleast if you move in the day these dangers are less likely to occur and if they do you atleast have some sense of visual idea. Although if a lion decides he wants to eat you i dont think there is much else you can do...

Support: While it may be true that many poisonous animals and other predators hunt at night, it is still better to travel at night for two reasons:

1. You have a better fighting chance against being attacked by a poisonous animal if you are awake rather than asleep.
2. Dying from dehydration is much more likely so it is critical to conserve whatever water is in your body as much as possible ie. rest when it is hot so you sweat less.

Hundreds of expert survival groups recommend it for similar reasons, but with more detail. Wilderness medical Society[1], Global Crisis Solution Center[2], and the Survival Guide [3], just to show a few.

Oppose: That's why you build a fire...
