5 incredible facts about our bodyVika
The human body is a riddle on a riddle. Inside us, amazing and unusual things happen every day, which we do not even suspect. Fullpiccha will share with you amazing facts about our bodies that seem fantastic at first glance.
1. Almost 100% renewal of the body in 10 years.
Every day, about 70 billion cells die in our body, but we do not suspect it. It sounds creepy, but other cells appear in their place. GI cells are renewed every 3-4 days, red blood cells are renewed every 3 months, and kidney cells are regenerated throughout the year. For 10 years, our body undergoes almost complete regeneration. But there are cells that live for over a hundred years, such as neurons.
2. We are taller and thinner in the morning.
It is well known that the intervertebral discs during sleep are not so tightly adjacent to the vertebrae. And as soon as we wake up, our height is 1-2 cm higher than usual. Many may also notice that in the morning, after getting on the scale, we see a decrease in weight. The fact is that in a dream, our body continues to work and metabolic processes do not slow down their activity in order to get rid of unnecessary fluid. It is surprising, but it is important to watch out for symptoms such as thinning of the intervertebral discs or protrusion. But usually, such diseases are characterized by severe pain syndrome, and the treatment of protrusion of intervertebral discs is primarily aimed at relieving pain.
3. Gastric juice can dissolve iron.
Our stomach contains hydrochloric acid, which is capable of dissolving iron. But how does our stomach withstand such loads? The answer to the first point is the regeneration of stomach cells.
4. Your emotions can change your memories.
Our memories change every day depending on our current emotional state. For example, you went on a romantic trip with your girlfriend last year, but after a while, you had a fight and broke up. Now, remembering your trip, you will think that you were not so much fun and even find something bad.
5. Your navel is a whole ecosystem for bacteria.
It sounds creepy, but each of us has tens of thousands of bacteria in our navel that have formed their own ecosystem. We can say that there is a small world in your navel. Scientists say it looks like a rainforest.
