The human body is very complex collection of numerous biological cycles and systems that regular people don’t often fully understand. Our bodies have a set of defense mechanisms which constitute different systems. They protect us from a whole number of things that could potentially harm us. There are some of our involuntary movements and functions that are really strange defense mechanisms for our bodies that we never knew about. Here are eight interesting things that your body does and that we might not even realize were ranked among those defense mechanisms.
1. Yawning: The main purpose of yawning is to allow the brain to cool down after an overwhelming amount of work that may have caused it to overload.
2. Sneezing: Sneezing is another defense mechanism that usually occurs when our nasal passages fill up with too many allergens, microbes, dust, and other irritants. Sneezing is the body’s way to get rid of all that trash.
3. Stretching: We instinctively stretch to prepare our bodies for expected physical loads. Stretching also works the muscles, restores blood flow, and improves our mood.
4. Hiccupping: Eating too fast, swallowing large bites of foods, or simply overeat, can cause our pneumogastric nerve to irritate. This is closely linked to the body’s stomach and diaphragm. So the hiccups show up as to protect our stomach and diaphragm.
5. Myoclonic jerks: This refers to the strange feeling when you lie down to go to sleep and as you starts to drift off your body is jolted for a second by what it resembles an electric shock. In this moment, all of your muscles spasm so strongly that you almost fall out of bed, and you immediately wake up. This phenomenon happens due to the fact that when you begin to fall asleep, the frequency of your breathing rapidly falls, while the pulse slows down only very slightly and your muscles are relaxed. Unbelievably, your brain interprets these developments as heralding death, so it tries to save you by giving you a jolt.
6. Wrinkling of the Skin: The wrinkles appear on the skin when the body realizes that the moisture around us increases, it understands that the environment might be slippery so it adapts through the wrinkling of the skin. This wrinkling makes it easier for you to grip smooth and slippery surfaces.
7. Loss of Memory: Loss of memory happens after the occurrence of painful experiences. Our brain
literally deletes the unpleasant encounters from our memories.
8. Goosebumps: It happens to reduce the amount of heat our bodies lose through the pores of our skin, which then makes it easier to warm ourselves in cold weather.
