Fresh water vs. Salt water

You can't drink saltwater, but you need both freshwater and salt!

Distill freshwater by boiling it for at least two minutes (biohazard)

​Evaporate salt water to obtain concentrated salt, otherwise fatal organ failure will occur.

Animals lick rocks to get vital minerals.

​

Three minutes without air (or in icy water)

 Three hours in a harsh environment (extreme heat or cold)

Three days without fresh water (eating snow will only increase the level of dehydration)

Three weeks without food (Max. 40 days and 40 nights)

​

It takes energy to digest a hot meal to get new energy.

A hot meal right before going into the sleeping bag is optimal for a good night's sleep.​​​​​​​​​
