If Your Body Twitches Before You Go To Sleep, This Is What It Means
If you’ve ever felt a sudden jolt just as you’ve started falling asleep, then you’ve experienced what is called a hypnic jerk. A hypnic jerk is an involuntary twitching of a muscle or muscles. It is actually a normal thing to happen since 70% of people experience hypnic jerks at some point in their lives.
Just as you are falling asleep, you are in what’s known scientifically as the hypnagogic state of consciousness. If your body is really exhausted, your brain will try to fall asleep too quickly and it will confuse itself into thinking that the major systems of the body are failing. That is why your body makes you jolt and jerk you.
