Human cell replacement is relatively common, and far more common than you’d think. In fact, some human cells replace themselves every minute. With cells dying and being replaced with new ones, it allows for people to remain healthy. How many human cells are replaced every minute?
Did you know that about three hundred million cells in the human body die every minute! But they are replaced with a similar number of healthy cells every minute also. These cells include, but are not limited to blood, hair, stomach lining, fat and skin. Red blood cells for instance last about four months. White blood cells will live for over a year, and skin cells only last for a few weeks. Those cells have a fairly long existence compared to others such as the colon, around four days, and sperm, which die after approximately three days. The brain cells last a lifetime. Even though each type of cell has a different life span, each type doesn’t get replaced all at the same time. For instance, all of the red blood cells won’t die at once and be replaced at once. Some will die this minute, some the next, and so on. The fact that the cells can be replaced and replenished so efficiently is the reason blood donation works. But why would a relatively healthy body need to replace so many cells so often?
This cell replacement is needed to help maintain proper and efficient function of your body. While 300 million cells seems like a huge number, it must be remembered that each cell is microscopic in size.
Are there any risks to you with so many human cell replacements a day?
In short there are always risks. Cancers are caused by a mutation of a normal cell while it is being produced. But the chances of any harm coming to you are minimal. It’s also worth remembering that without cell replacement on a regular basis you would surely die at an extremely young age.
