Everybody has experienced that weird feeling of drifting off while you are trying to fall asleep, at least once in their life.
It might be a sensation like something is hitting you or a sensation that you are falling down, but it always comes down to the same thing. This is a phenomenon, that the science was unable to fully explain for a long time, but the recent scientific studies seem to be pointing out one particular thing.The scientists have called this phenomenon “hypnic jerk”. It is most commonly described as a sensation of falling down, where you immediately wake up afterward, and you are in a state of shock. This is of course experienced differently by different people, and there are some instances where people are feeling that they are getting choked, or getting hit by something.
Why our bodies jerk while falling asleep?
If you are experiencing this phenomenon regularly, then it is an indicator that you should avoid tobacco and caffeine as much as you can, because of the fact that these two ingredients have been scientifically proven to stimulate this sensation in many cases. Another thing that leads to this sensation can be the fact that you are not getting enough sleep, or if you are taking medications like Adderall and Ritalin.
This is a sensation which is a symptom of tiredness of the body and brain, which makes our brain think that we are not actually falling asleep, but rather falling down. This makes the brain send warning signals to the body, in a form of a shock, in order to wake it up.
But, the main idea behind this phenomenon is that our brain is causing our body to dream of things that would shock us, just so it can quickly wake up the body.
