Water is equally important for people, just like air. In dry areas, people must secure a source of water every day. In case you are left without it, you need to get acquainted with as many way of collecting it as possible. Also, it is important that it remains drinkable and in a safe place. In general, an adult can stay alive for 3 minutes without air, 3 days without water and 3 weeks without food. So, water needs to be a priority.
One mustn't wait until all the reserves are used up- a new source of water needs to be sought out immediately. In a situation where you need to survive, 1 litre or water can last up to 4 days and, if necessary, the last 1/4 can last up to 3 days. The human body loses 2-3 litres of water a day which means that this amount needs to be replaced with drinking liquids or eating food which, to some extent, consists of water. An increase in activity and temperature means that we lose more liquids by breathing or sweating. The water inside of our organism is responsible for a number of vital functions such as extracting waste, supplying with energy, regulating body temperature and retaining mental sharpness. In order for a man to be healthy and entirely functional, he needs to have access to an amount of water that will get him through the day.
