Tag: Extreme dehydration

The human body is composed of 50 to 75% water, a vital component for nearly every bodily function, from regulating temperature to lubricating joints. A person cannot survive for 14 days without it; in fact, the average person will not survive more than three to five days, depending on conditions.

While humans can endure for weeks without food, the maximum time a person can survive without water is a mere matter of days. Water is a fundamental requirement for nearly all bodily processes, and its absence initiates a rapid and dangerous cascade of systemic failures.

According to the Mayo Clinic, severe dehydration can be life-threatening and is caused by an insufficient intake or excessive loss of fluids. Knowing the definitive signs of extreme dehydration is crucial for identifying a medical emergency and seeking prompt treatment before serious complications arise.
