We all know that our bodies are amazing, complex, intricate and fascinating because they keep us healthy and safe every second of our lives. Our body actually protects us from any harm just by a simple action like sneezing or yawning. Moreover, our body has a defense mechanism, which is why sometimes we get the hiccups or our fingers wrinkle in water.
You have probably noticed at some point in your life that after a longer period of time under water, your fingers get wrinkled. Well, those wrinkles actually have a specific purpose. Once our body encounters an increased amount of moisture, it realizes that the outside environment might be slippery, which is why our skin begins to wrinkle. In that way, we can get a better grip on smooth surfaces. This is amazing, isn’t it?
In this article, we will present you some of the body’s other defense mechanisms and here are some of them:
The reason why we sneeze is because our nasal passages fill up with too many microbes, dust, allergens and other irritants. By sneezing, we actually clear our airways of any irritants.
You have probably noticed that sometimes when you wake up, you feel the need to stretch a bit. Stretching is actually a habit which prepares the body for the upcoming day. By stretching, you work your muscles and restore blood flow after a long night’s sleep. It also improves your mood!
People usually get goosebumps when it is cold outside. They actually occur in order to help to reduce the amount of heat the body loses through the skin. This means that whenever you are cold, goosebumps help keep you warm.
When people yawn, they usually think that they are very tired, which is partly true. However, it actually means that your brain is tired. The main reason why our body reacts with yawning is because it needs to cool down the brain after it’s been overheated or overloaded.
According to many scientists, tears are in fact a new source of irritation which are created by the body in stressful situations in order to distract you from the pain you are experiencing. In other situations, tears act as protection for the mucous membrane if the eye when foreign object comes into contact with it.
Even though very annoying, hiccups also occur for a reason. For instance, they occur due to fast swallowing of large pieces of food or overeat, and as a result of that, the pneumogastric nerve becomes irritated. The nerve is closely connected to the stomach and diaphragm which is the main reason why the irritation results in hiccups.
- Memory Loss
Unpleasant experience is most commonly the major reason why memory loss happens. For instance, if certain event left you hurt or upset, the brain deletes it from your memory in order to prevent it from being remembered once again.
