You’ve probably wondered how it is that the human body can survive for a really long time, all things being equal. Well, our bodies are built to survive and stand the test of time. The body has mechanisms put in place for it to stay alive for a long time. I’ll show you 9 ways it does this.
1. The human mind sheds information (old ones, especially), so as to avoid over working itself, and to make room for newer information. This process also allows for quicker thinking and understanding.
2. The stomach secretes acidic content, which can destroy the lining of your stomach. However, to make sure we’re safe and healthy, the stomach produces brand new lining every other 3 or 4 days.
3. Due to the body’s ability to heal, we live way longer than we ordinarily might. When you have a cut, the body stops the bleeding soon, and then, replaces whatever cells might have been destroyed as a result of the injury.
4. The human body has the ability to identify disease-causing pathogens that have attacked it in the past, and then, destroy them, to keep itself safe.
5. The liver has the ability to replenish itself, and re-grow, if a part of it had to be removed due to an infection or surgery.
6. The body can sustain itself for long even when starved— how does it do this? It uses the glycogen stored to keep you going for about 6 days or more, before it turns to fats and ketone bodies, and then, protein. A human can stay as long as 70 days without food due to this amazing mechanism, however, it largely depends on factors like weight, and amount of fat in a person.
7. When a pregnant woman suffers damage to an organ, the baby in her womb sends stem cells to repair the damaged organ.
8. The body sheds between 30,000 and 50,000 skin cells every minute. This is all to keep itself healthy and get rid of harmful substances on the skin, as well as replace all dead skin cells.
9. Every time you shiver or sweat, it’s your body trying to keep you healthy and maintain the right temperature for itself. The normal temperature level for the body is 37 degrees Celsius. Anything above or below that can lead to death.
Now you know some of the ways the body keeps itself alive and going. Hope you found this interesting.
