Did you know our body does these strange things due to Defense Mechanisms

Our bodies consist of a complex collection of many biological cycles and systems that may be tough to decipher. Our body’s set of defense mechanisms constitute one of them. They help in preventing any potential harm or damage to us. We bring you a list of some of these defense mechanisms.

1 Yawning

The reason we yawn is for the brain to cool down if it is overloaded or has been overheated. You may also yawn if you are bored, sleepy and tired. It also happens when someone around you yawns. Stress and hunger also lead to a yawn.

2 Sneezing

Sneezing is one the natural defense mechanisms of the body. Its main purpose is to expel mucous containing irritants from the nasal cavity. It is also known as sternutation. The irritants could be germs, dust, pollen, animal dander or pollutants. When these enter the nose, the brain sends a signal to throw it out. This triggers a deep breath which gets held in the lungs and is released in the form of a sneeze.

3 Stretching

Every morning as you wake up, as if acting upon an instinct, you automatically feel like stretching out your body. It helps in increasing flexibility and motion in the muscles and joints. It is also said to improve circulation and relieves stress and tension.

4 Hiccupping

Hiccups occur due to eating or drinking too much or too quickly. Due to this the stomach which is located below the diaphragm gets distended and irritates it. Then the diaphragm contracts, just as it happens when we breathe in. Hiccups also can be caused due to changes in the temperature or during emotional situations.

5 Myoclonic Jerks

Sometimes just as you are about to fall asleep, your body is jolted for a second; sudden jerks take place which seem more like an electric shock. You may even wake up due to the intensity of the jerks. This happens due to the fact that when you are about to fall asleep, the frequency of your breathing reduces and your pulse slows down as your muscles begin to relax. The brain interprets these actions as impending death and so it tries to save you by giving you a strong sudden jerk.

6 Wrinkling of Skin on Fingers

The skin of the hands and feet has the thickest layer of dead keratin cells. So while a person puts his hands in water for a long time, the dead keratin cells absorb water. This action causes the surface area of the skin to swell, but the outer layer is tightly attached to the living tissue. So, to compensate for the increased surface area, the skin on these areas wrinkle.

7 Memory Loss

This happens due to people wanting to erase unpleasant memories or experiences. The brain erases hurtful memories in order to reduce anxiety.

8 Goosebumps

Goosebumps occur on our skin as a reaction to cold, shock, fear, nostalgia and maybe extreme excitement. The bumps get created when muscles at the base of the hair contract and cause the hair to stand straight.
