Human body: everyday things we do that are actually defense mechanisms - The human body is smarter than we think. Everything that we think is a result of chance, actually has a purpose. Yawning is a way to wake us up, sneezing protect us, and sweating is a way to control our body's temperature. Discover the true meaning of the things our body do every day!

Hiccups - When we eat too fast we can irritate our pneumogastric nerve, causing an anomaly between the stomach and the diaphragm. The result is that you begin to hiccup in effort to normalize the situation.

Ghost vibrations - Have you ever felt something vibrating and thought it was your cell phone? The most likely explanation for this is that your brain is misinterpreting the signals it is receiving from your body, giving you the sensation that something has vibrated.

Myoclonus -

Have you ever been drifting off to sleep when you suddenly feel a twitch? These are spasms created by the body to make it come back to life. When we are very tired our breathing decreases a lot and the body 'thinks' that we are going to die so it gives us a jolt.

Super strength - In situations of extreme risk, it often seems that we gain strength that we thought we did not have. This is not by chance, since in these situations the body contracts all of your muscles at once, helping to withstand great forces.

Sweat - Our body produces sweat as a way to regulate our body's temperature so that we don't overheat.

Lump in the throat - The sensation of a lump in the throat arises essentially when we receive bad news that causes us anguish. Our body gets into 'fight or flight' mode and our muscles work against each other.

Motion sickness - The movement of vehicles can lead to a signal miscommunication between our vision and our body, provoking nausea, vomiting and a general feeling of sickness.

Goose bumps - It's not by chance that we get goose bumps, it is our body's attempt to reduce heat loss, raising hairs to insulate the body and keep body temperature stable.

Blinking - Blinking is a mechanism used by the body as a form of protection and care. Through the act of blinking, we lubricate and rest our eyes, which can not remain permanently open.

Memory loss - The brain also tends to eliminate negative episodes of our lives. It is a form of defense that our body uses to protect us.

Numbness - Our body gets numb when we are in the same position for a long time. Staying still causes the nerves to become compressed in these areas, causing a numbing sensation.

Sick to your stomach - In dangerous situations, our brain releases a discharge of adrenaline that contracts blood vessels in the abdomen, and this is why you feel 'sick to your stomach.'

Eyelid twitching - Eyelid twitching can be caused by stress, lack of rest, excessive consumption of caffeine or alcohol, or dehydration.

Smell - Our sense of smell has a memory. A lot of the time when we smell something we are transported to another place, or a specific time.

Pupils - When we are in love or we like someone our pupils tend to dilate.

Crying - Surely you have heard the expression 'crying is cathartic.' Crying is also a body mechanism to lubricate the eyes, and at the same time, relieve emotional pain.

Falling asleep - You have probably fallen asleep on the sofa while watching TV at some point. When not stimulated, the brain slows down and breathing slows down, making us relax and eventually fall asleep.

Eyes - Our eyes also warn us when our body is colder than normal. Studies show that when body temperature drops to the point of causing hypothermia, blood vessels in the eyes compress to save energy.

Bones - Our bones are one of the toughest materials in the world, capable of withstanding tons of weight. Our skeleton itself is a body defense.

Tickling - Tickling is a reaction to situations of fear and panic. That is why we laugh when we get tickled, because it is a way for the body to react in case of danger.

Yawning - When we yawn it is not just a warning that we are tired, it is also a mechanism that the human body uses to refresh the brain and reduce nervous tension.

Wrinkly fingers - When we spend a lot of time under water, the skin on our hands tends to look like this. The body uses this mechanism so that we can better grasp objects and hold onto smooth surfaces more easily.

Left and right handed - Studies have shown that left-handed people are stronger than right-handed ones. For left-handed people, it is easier to open a jar, but for the right-handers it is easier to close it. This is because they use different hemispheres of the brain.

Sneezing - The powerful expulsion of air from our noses happens so that the viruses and bacteria are expelled from our bodies, since they can cause allergic reactions or even dangerous diseases.

Stretching -

Stretching is a form of preparation for the day. When we do this we are helping to activate muscles, and consequently stimulate blood flow.

Stretching - In addition, stretching can also raise your mood and prepare your body for exercise.

Alcohol and memory - Studies show that excessive alcohol consumption can prevent the brain from transferring data from short-term memory to long-term memory, which may lead to memory loss.

Appendix - The appendix is often thought of as something that our body doesn't need. However, we have this organ as a refuge for the good bacteria that live in our gut.

Ears - The right ear tends to listen better when we are surrounded by noise at a party, while the left ear will focus better on the music around you. This has to do with the hemispheres of our brains, one is more rational, and the other one more emotional.

Height -

When we wake up, we are a few centimeters taller than when we go to bed. This is because the vertebrae of your spine are separated by discs and in the morning these are more aligned than at the end of the day.
