What Do We Need to Survive?
All human beings have certain physiological needs that are crucial for our survival. These things are necessary for us to thrive and maintain a healthy life. This article will look at the basic needs all people have, and why you need to understand all of them if you intend to survive in an extremely harsh, barren or stressful situation.

Human Survival Essentials
1. Oxygen
Oxygen is absolutely necessary and crucial for our existence. Breathing and sustaining our bodily processes hinge on the availability of oxygen. If we lack oxygen, our organs and muscles would cease to work, causing us to lose consciousness in just a few minutes. The blood carries oxygen to all our crucial body parts, guaranteeing their appropriate operation.
2. Shelter
Shelter is another crucial human need for survival. It provides protection against extreme weather conditions, such as rain, and snow. A good shelter keeps us safe from physical harm and injury. It also serves as a place where we can rest and seek comfort. Without shelter, we would be exposed to the elements, which can have detrimental effects on our health and well-being.
3. Water
Water is a critical requirement for human survival. Our bodies are made up of approximately 60% water, and it plays a crucial role in preserving our overall health and well-being. Water is necessary for hydration, regulating bodily duties, and transporting crucial nutrition and oxygen to our cells. It also aids in breaking down foods and excretion of excrement from our bodies. Without an adequate supply of water, we would suffer from dehydration and other health complications.
Maintaining the right temperature
1. Body regulation
Keeping the right body temp is crucial for our survival. Our body operates optimally within a narrow temp range. If our body temp deviates significantly from the normal range, it can lead to various health problems, including heatstroke or hypothermia. Our body has natural mechanisms, such as sweating or shivering, to regulate body temp and keep it within the appropriate range.
2. Prevention of hypothermia or hyperthermia
Maintaining the right temps prevents the development of hypothermia or hyperthermia. Hypothermia occurs when our body loses heat faster than it can produce, leading to dangerously low body temp. On the other hand, hyperthermia occurs when our body overheats, usually due to exposure to high temps or strenuous physical activity. Both conditions can be life-threatening if not addressed promptly.
3. Impact on bodily operations
The right temperature is essential for the proper functioning of our bodily processes. Enzymes, which play a crucial role in various biochemical reactions in our body, function optimally within a specific temperature range. Deviations from the optimal temperature can affect enzyme activity and hinder essential bodily functions.
What role does protein play in our survival?
1. Building and repairing body tissues
Protein is an essential nutrient that plays a vital role in building and repairing body tissues. It is the key component of muscles, organs, skin, hair, and nails. Protein is made up of amino acids, which are the building blocks of our body. Without an adequate supply of protein, our body would struggle to repair and regenerate tissues, leading to impaired growth and development.
2. Enzyme production and function
Protein is also involved in the production and function of enzymes, which are responsible for catalyzing biochemical reactions in our body. Enzymes are necessary for various metabolic processes, such as digestion, energy production, and detoxification. Without sufficient protein intake, enzyme production and function can be compromised, affecting the overall functioning of our body.
3. Providing energy when carbohydrates are insufficient
In addition to its structural and enzymatic roles, protein can also provide energy when carbohydrates are insufficient. While carbohydrates are the body’s primary source of energy, in the absence of an adequate carbohydrate supply, our body can break down protein for energy production. This process is known as gluconeogenesis and ensures that our body has a constant supply of energy, even in times of carbohydrate restriction.
Clothing Functions
1. Protection against extreme weather conditions
They serve as a protective barrier against extreme weather conditions. It helps us stay warm in cold temperatures and provides crucial insulation to prevent heat loss from our body. They also protects us from the harmful effects of the sun, such as sunburn or overexposure to ultraviolet (UV) radiation. Additionally, they can offer protection against rain, snow, wind, and other environmental factors.
2. Insulation and temperature regulation
They act as an insulating layer that helps regulate our body temperature. It traps a layer of air close to our skin, which serves as insulation and reduces heat transfer between our body and the environment. In hot climates, they made from breathable materials can help wick away sweat and promote evaporation, cooling our body and preventing overheating.
3. Preventing physical injury and harm
Wearing appropriate garments can prevent physical injuries and harm. It provides a layer of protection against abrasions, cuts, and puncture wounds. Specialized garments, such as safety gear or protective gear, can offer additional protection in hazardous environments or during specific activities. By wearing suitable apparel, we minimize the risk of accidents and injuries.
Water
1. Hydration and regulation of bodily functions
Water is essential for hydration and maintaining the balance of bodily fluids. It is involved in regulating body temperature, lubricating joints, and cushioning vital organs. Water also facilitates the transportation of nutrients, oxygen, and waste products throughout our body. Without an adequate water supply, our bodily functions would be compromised, leading to dehydration and various health complications.
2. Transportation of nutrients and oxygen
Water plays a crucial role in transporting nutrients and oxygen to our cells. It serves as a medium for these essential substances, allowing them to be transported efficiently to where they are needed in our body. Without sufficient water intake, the delivery of nutrients and oxygen to our cells would be hindered, affecting their proper functioning.
3. Proper digestion and excretion
Water is necessary for proper digestion and excretion of waste from our bodies. It helps break down food in our digestive system, enabling the absorption and utilization of nutrients. Adequate water intake also ensures the smooth movement of waste through our intestines, preventing constipation and promoting regular bowel movements. Without enough water, our digestive system would struggle to function properly, leading to digestive issues and discomfort.
