9 Strange Things Your Body Does That You Never Knew Were Defense Mechanisms

Our body is a complex collection of many biological cycles and systems which can be really difficult for understanding.

The set of defense mechanisms of our body constitute one system. They have a responsibility to protect us from any kind of damage, 24 hours a day 7 days a week.

We will present you 9 incredible things that our body does and are ranked among those defense mechanisms.

1. Sneezing

We sneeze when our nasal passages are filled with a lot of allergens, dust, microbes and various other irritants. Sneezing is the way in which our body eliminates this “trash”.

2. Yawning

The main purpose of yawning is to cool down our brain after being overheated or overloaded.

3. Stretching

Stretching is an instinctive act which we make so we can prepare our body for the physical loads we expect to take them throughout the day. Stretching at the same time restores blood flow, improves our mood, and works our muscles.

4. Hiccuping

The fast eating, overeating or swallowing large pieces of food can irritate our pneumogastric nerve. This is related to our diaphragm and stomach. And the result is a bout of hiccups.

5. Wrinkling of the skin

The wrinkles that appear on your hand skin have a very important role. This is caused when your body faces an increased amount of moisture it understands that the environment may be slippery. Thus, the skin of the hands begins to change immediately so you will be able to grip smooth surfaces.

6. Myoclonic jerks

This is the feeling when you lie down to sleep, and you start to drift off and your body is jolted by something that seems like an electric shock. All of your muscles spasm so strongly, which makes you think that you almost fall out of the bed and you wake up immediately.

When you begin to fall asleep, the frequency of your breathing rapidly falls, your pulse slows down and your muscles are relaxed. Your brain interprets these developments as heralding death. So it gives you a jolt in order to save you.

7. Goosebumps

The main purpose of goosebumps is to reduce the amount of heat our body lose through the pores of our skin, thus making it easier to warm yourself in in inhospitable climatic conditions.

8. Loss of memory

This often occurs after some unpleasant experiences. So, the most terrible moments from our memories are deleted by our brain.

9. Tears

Besides protecting the eye mucous membrane when foreign objects come into contact with it, the tears act as an “emotional defense”. According to scientists, our body creates a new, powerful source of irritation in stressful situations to distract the person from the pain they are experiencing.
