According to my research and understanding, the following are the five most important essentials needed for the human body's survival.
Air
Air in the earth's atmosphere is composed of various gases such as nitrogen, oxygen, hydrogen, etc. Here, oxygen is most important for human survival. Our bodies require a regular supply of it to function correctly.
The human body can experience a condition known as cerebral hypoxia in case of its deficiency.
Water
Water is another essential element of life. According to the latest research, human bodies are made up of 70% water. We utilize water to keep our temperature regular. Then it also plays an essential role in digesting the food and gets rid of waste. Therefore, we have to keep ourselves hydrated during the day. That is precisely why it is crucial to stay hydrated.
The dehydration process starts whenever the body is unsuccessful in keeping a hydration balance. Research shows that a 2.5% loss in water volume in a person could cause a 25% reduction in blood volume. In extreme cases, this means the blood would get thicker, and the heart has to work harder to pump out nutrients inside the body.
Food
Food is essential for the body as it helps produce energy that is then used in daily routine activities. Medical and researchers believe that body can survive quite a while without food. However, it is dependent on the adjustment, energy consumption, and metabolism of the human body.
It isn't easy to accurately estimate the survival time of the human body. However, research studies have shown that survival time ranges from thirty to forty days.
Many social and religious groups frequently involve short-term fasting during hunger strikes for social causes and fasting for religious reasons. Your body would continue to operate normally for up to eight hours in the absence of food. In typical scenarios, the human body converts food into glucose, which helps in fueling the body.
However, people must keep in mind that too much fasting can cause deficiencies in the body. However, there is good news that many of these deficiencies can be countered and prevented by consuming a well-balanced diet.
People must also take fresh fruits and vegetables like broccoli and kale. They are beneficial alkaline foods. It is also imperative to include proteins such as meat, poultry, and fish which are considered acidic on the scale. Some people try to decrease protein intake, which is a wrong approach. People must keep a balance of alkaline to acidic foods to help their bodies buffer acidity and achieve optimal health. Therefore, it is crucial to consume good fresh fruits and vegetables to fuel your body with essential vitamins and minerals.
Shelter
A shelter and appropriate clothing play an essential role in safeguarding your body and keeping it at a safe temperature. People often face the problem of water loss while going on outdoor activities. Moreover, winter temperatures and wind can strip away precious moisture quickly as hot temperatures can cause sweat-linked loss.
Whenever the human body is unsuccessful in maintaining a steady temperature, it risks hypothermia or heat stroke.
Survival tools
Survival tools are significant people who love to go outdoor for various healthy activities such as camping, hiking, biking, etc. They protect you if you encounter any unforeseen event. The list of survival tools includes a Swiss knife, matches, tinder, first aid kit, bandana, fish hooks, sewing kit, and a flashlight.
Bottom Line
The mentioned above tools, natural gases, and food items are essential for human survival. However, people have to make sure that they are taking them in proper quantities.
