10 Things That Could Mean Life or Death for Humans

There are certain things that humans simply cannot survive. These are extreme conditions or situations that can be deadly to even the healthiest of individuals. Understanding what these things are can help us to protect ourselves and improve our chances of survival.


  1. Extremely high temperatures: Humans cannot survive in temperatures that are too high or too low for extended periods of time. For example, temperatures above 120 degrees Fahrenheit or below -40 degrees Fahrenheit can be deadly. It is important to take measures to protect ourselves from extreme temperatures, such as wearing appropriate clothing, seeking shelter, and staying hydrated.

  2. Lack of oxygen: Oxygen is essential for human life, and without it, we will quickly die. It is estimated that we can only survive for a few minutes without oxygen before suffering serious brain damage. It is important to be aware of our surroundings and take steps to ensure that we have a constant supply of fresh air.

  3. Prolonged exposure to radiation: Exposure to high levels of radiation can cause serious health problems, including death. This can come from sources like nuclear accidents or prolonged exposure to the sun without proper protection. It is important to be aware of potential sources of radiation and take steps to protect ourselves, such as using sunscreen or avoiding areas with high levels of radiation.

  4. Extremely high or low pressure: The human body is not built to withstand extreme changes in pressure, such as those found at high altitudes or deep underwater. These changes can cause serious health problems, including death. It is important to be aware of the risks associated with high or low pressure environments and take steps to protect ourselves, such as using proper safety equipment.

  5. Lack of water: The human body needs a constant supply of water to function properly, and severe dehydration can be deadly. It is estimated that we can only survive for a few days without water before suffering serious health problems. It is important to stay hydrated and have a supply of clean water available in case of emergencies.

  6. Starvation: Humans need a constant supply of nutrients to survive, and prolonged starvation can lead to death. This can happen due to a lack of food or an inability to properly process and absorb nutrients. It is important to have a balanced diet and seek medical attention if we are experiencing problems with malnutrition.

  7. Drowning: The human body is not able to survive for long periods of time without air, and drowning can occur in just a few minutes. This can happen in any body of water, including oceans, lakes, and even bathtubs. It is important to be aware of the risks associated with water and take steps to protect ourselves, such as learning how to swim and using proper safety equipment.

  8. Prolonged isolation: Humans are social creatures, and prolonged isolation can lead to mental and physical health problems. This can include things like depression, anxiety, and even physical ailments like muscle atrophy. It is important to maintain social connections and seek help if we are struggling with isolation.

  9. Certain diseases: Some diseases, such as cancer or HIV, can be fatal if left untreated. These diseases can damage the body's systems and eventually lead to death. It is important to seek medical attention if we are experiencing symptoms and to take steps to prevent the spread of disease, such as washing our hands frequently and getting vaccinated.

  10. Old age: While not necessarily a single event or circumstance, aging is a natural process that ultimately leads to death for all living organisms. As we age, our bodies become less able to function properly, and eventually, death occurs. While we cannot prevent aging, we can take steps to maintain our health and improve our quality of life as we age.



In conclusion, there are many things that humans cannot survive, including extreme temperatures, lack of oxygen, prolonged exposure to radiation, extreme changes in pressure, lack of water, starvation, drowning, prolonged isolation, certain diseases, and old age. Understanding these risks and taking steps to protect ourselves can help us to improve our chances of survival in difficult situations. It is also important to seek help and medical attention when necessary in order to improve our chances of survival and overall health.
