According to psychologist Abraham Maslow, the foundation of human motivation rests on a set of fundamental requirements known as physiological needs. This term is used to describe essential needs such as food, water, and shelter, which are vital for survival. Understanding these core needs is the first step toward appreciating the complex factors that drive human behavior and societal well-being.

The human body is approximately 60% water, and survival without it is typically limited to just a few days, depending on conditions. Knowing how much water does a person need in order to survive is not a fixed number but depends on numerous individual and environmental factors.

Globally, an estimated 149.2 million children under the age of five are stunted due to undernutrition, highlighting a powerful truth: nutrients are a survival need. This is not merely a matter of optimal health, but a fundamental requirement for life itself, fueling all cellular processes and development.

Over 90% of the human body is composed of water, highlighting its critical role in survival and growth. Understanding what organisms need for growth is fundamental to biology, as all living things, from microscopic bacteria to complex mammals, depend on a specific set of resources to increase in size, develop, and reproduce.

On average, a sedentary adult male requires about 1,600–1,800 kcal/day just for basal metabolic functions, while a female needs around 1,300–1,500 kcal/day. But this is just the minimum, and understanding how much energy does a human need to survive properly is a more complex equation, dependent on many variables beyond basic existence.
