FINDING LIFE-GIVING LIQUID
You need to drink several litres of water every day. Here’s how to find it
Without water, you’ll die in a few days. Your body is three-quarters water by weight. You lose water when sweating, peeing and pooping. This all has to be replaced. Even in comfortable climates your body needs about two litres a day to stay healthy. You need much more if you’re travelling in hot places. Some recommend drinking a litre for every four miles covered, even if travelling at night, and twice that in the day. In cold places you also need more water because it’s harder to move around and you need to generate more heat. You also need water to cook with, and to keep yourself clean.
