What role water plays for us and how long you can survive without food

the German Society for Nutrition recommends a day at least 1.5 liters of water to drink. In high heat or when you do sports, even half a liter to a full liter of water per hour can do additionally necessary be. the Technicians’ Health Insurance points out that the recommended amount of water does not necessarily have to be drunk completely. Our body can produce around 300 milliliters itself during its metabolic processes. He also gets about another liter from solid food: Apples, vegetables and potatoes, for example, contain around 70 percent water, and cucumbers even 95 percent.

The human body consists up to 70 percent of water. How high the proportion actually is depends on your age and gender. filled with water important tasks in the human body. Among other things, water forms the body as a component of cells and tissue, dissolves solid components such as salt or sugar from food and carries dissolved nutrients to the cells.

These explanations about the importance of water for the body show that for liquid other rules are considered for food. How long a person can survive without water could only be found out based on observations of dying people. For example, one explained biology professor George Washington University told NBC News in 2013 that the Maximum time at one week lie.

The concept of maximum time is deliberately chosen here; a shorter period is more likely. That’s how you start three to four days out. Especially when you extreme situations such as severe physical exertion or heat, the likelihood of surviving a week without water is very small. In the interview, Claude Piantadosi introduced Duke University scientistsfrom that one at moderate temperatures about 100 hours could survive.
