The body is about 60% water, give or take. We're constantly losing water from our bodies, primarily via urine and sweat. There are many different opinions on how much water we should be drinking every day. The health authorities commonly recommend eight 8-ounce glasses, which equals about 2 liters, or half a gallon.
Every system in your body depends on water. For example, water flushes toxins out of vital organs, carries nutrients to your cells, and provides a moist environment for ear, nose and throat tissues. Lack of water can lead to dehydration, a condition that occurs when you don't have enough water in your body to carry out normal functions. Even mild dehydration can drain your energy and make you tired.
So how long can you survive without water? Humans in average shape and perfect conditions can probably live for three to five days without any water if they're not physically exerting themselves. Healthier people can live a day or so longer, while those who are unhealthy or exposed to particularly hot or cold weather may not survive as long.
In a survival situation these are the things that you have to be aware of. Your body needs water to keep you alive. Lack of water causes many issues. Always be prepared with plenty of water and always have extra water with you in reserve. You can never carry too much water with you during a camping trip or on a mountain hike.
