The top 5 "can't live without" items generally fall into two categories: basic survival (air, water, food, shelter, clothing) and modern lifestyle essentials (phone, coffee/hydration, comfort items like a pillow or blanket, connectivity, and personal care/skincare), with many people finding their personal lists include a mix of these, highlighting a smartphone, something for hydration (water bottle/coffee), and comforts like books or specific routines.
10 Things You Can't Live Without
Every living species requires 5 things to survive: food, water, air, shelter, and space. An area where an organism finds these five things is called a habitat.
Food, water, clothing, sleep, and shelter are the bare necessities for anyone's survival.
Humans cannot live without air, water, food and protection from the elements. But we can all live without most things.
The 7 Fundamental Human Needs
The four most commonly discussed rules of survival are 3 minutes without breathing, 3 hours without shelter in an extreme environment, 3 days without water, and 3 weeks without food.
Yet often the first thing you might need in a survival situation is shelter to protect you. Then you'll need a form of hydration, and then food.
According to Maslow's original formulation, there are five sets of basic needs: physiological, safety, love, esteem and self-actualization.
The 25 Most Important Things in Life: What Really Matters
One way to remember the 5 C's is by associating each one with a vital survival need: Cutting Tools for building and hunting, Cover for shelter, Combustion for fire, Containers for water and food, and Cordage for building and emergency medical aid.

The 7 Priorities of Survival
So here is my list of “things,” which I am interpreting as physical items:
Even short periods without air can lead to long- term brain damage, making oxygen the most urgent survival need. Water is the next most critical element. The human body needs water to control body temperature, move nutrients through the blood, and keep organs working properly.
15 Things You Definitely Don't Need More of
At the bottom of the hierarchy are the “Basic Needs”. These are the physiological needs of a human being: food, water, sleep, sex, homeostasis, and excretion. The next level is “Safety Needs: Security, Order, and Stability”.
It is most obvious that we all have physical or Survival needs such as the need for sleep, food, water, comfort and warmth. It comes as no surprise to learn that there are regulatory biological mechanisms in our bodies that help us to keep these needs in balance.
Key Takeaways
Needs Hierarchy: The original hierarchy includes physiological, safety, love/belonging, esteem, and self-actualization needs.
Basic Disaster Supplies Kit
You can survive for 3 Minutes without air (oxygen) or in icy water. You can survive for 3 Hours without shelter in a harsh environment (unless in icy water) You can survive for 3 Days without water (if sheltered from a harsh environment) You can survive for 3 Weeks without food (if you have water and shelter)
These 7 most important basic survival kit items are: food, water, first aid, warmth & shelter, sanitation & hygiene, lighting & communication, and other survival gear. Read our comprehensive checklist of survival gear and other necessities.
The Rule of Threes (in survival): Shelter — Three hours Water — Three days Food — Three weeks In other words, you should assume you can survive without shelter for three hours, without water for three days, and without food for three weeks. In an urban environment, the Rule of Threes still applies.
Humans rely on four essential pillars to stay alive: air, water, sleep, and food. Although each is critical for survival, the human body can endure their absence for varying lengths of time. Oxygen is the most urgent need, as the brain and vital organs require a constant supply to operate.
Pain, cold, thirst, hunger, fatigue, boredom, and loneliness are enemies of survival. In a survival situation, these feelings are more severe and more dangerous than in normal situations. Having knowledge of these feelings and their effects can assist in overcoming and controlling them.
