You are in the deepest place of sleep, or what is it when you have just gone to bed, just giving yourself a sweet sleep? You are falling rapidly from a very high place. In response to this situation, your limbs contract, you move independently of you and suddenly you wake up with a start.
This is what you're experiencing, Hipnic Jerk! It is also called "sleep concussion" or "hypnagogic jolt". It is usually severe enough to cause you to wake up from sleep. Very few people continue to sleep after this event, but it reduces the quality of sleep anyway. But what are the causes of this problem? Is it psychological? Is it physiological? Or is it just random?
Although Hypnic Jerk usually occurs for psychological reasons, it is very unlikely that it can occur for physiological reasons such as epilepsy. According to the researches, we are talking about the past to the present, that is to say, the periods lived in caves, which have not even passed into settled life; Since then, there are theses that we have multiplied, lived and continued our generation thanks to the Hipnik Jerk.
Now "What does this have to do with the Hipnic Jerk?" Do not be angry immediately. “Hypnic Jerk may be caused by a reflex from the past,” says our teacher, Psychologist Frederick Coolidge, from the University of Colorado. Since our ancestors spent most of their days in trees to protect themselves from predators, their wincing while falling asleep gave them the advantage of checking their safety. Those who experienced a Hypnic Jerk in the evolutionary process; While surviving, living longer and having more chance to reproduce, those who do not are eliminated.
Therefore, it may have been passed down by genes as a trait that increases the chances of survival. Based on this thesis, it is claimed that the Hipnik Jerk is an evolutionary feature inherited from our ancestors. Of course, if we say the Hypnic Jerk is entirely the fault of the genes, we would be shameful. So far, what we've said was actually the least likely. You are the reason for 60-70% of this situation.
