If Your Body Suddenly Jerks while Falling Asleep, this Is what It Means

According to Live Science, a hypnagogic jerk is an involuntary muscle spasm which happens as one is falling asleep. It has gotten the name because it has to do with the hypnagogic state, i.e. the transitional period between being awake and being asleep. They are commonly known as sleep starts or hypnic jerks. Let us learn more about why this happens…

Why Do Our Bodies Jerk while We Fall Asleep?

The spasms may happen all of a sudden or as a result of a sound, light or some other stimuli. In some people, the hypnic jerks are followed by dreams, hallucinations, a sense of falling, loud noises, or bright lights.

Believe it or not, this phenomenon is rather common and according to Live Science, somewhere around 60 to 70 percent of people experience it.

What Do Scientists Have to Say?

Some scientist assert that the contributing factors are too much caffeine, anxiety, tiredness, stress, and sleep deprivation and they may also elevate the severity or the frequency of the jerks. However, conclusive research on this topic is missing. It is also important to note that intense physical activity or strenuous exercising may also lead to hypnic jerks.

One possible hypothesis is that these jerks are a natural aspect of the body’s journey from alertness to sleep phase and happens when the nerves “misfire” during this process.

Another stand is that the spasms are an ancient primate reflex to the muscle relaxation happening during the onset of sleep and the brain misinterprets the relaxation for a sign that the primate is falling of a tree and thus, engages the muscles for a quick reaction.

Be that as it may, generally speaking, this phenomenon is completely normal and if you are experiencing it, you have nothing to worry about. Nonetheless, if the jerk or the anxiety surrounding it is significantly diminishing your quality of sleep, you should consult your physician or a sleep specialist and explain your concerns.
