What are Hypnic jerks and how can you deal with it?


Have you ever experienced waking up with a jerk like somebody threw you into your bed? Or perhaps you have tried to snooze and minutes after you felt like you are falling backwards from an enormous height towards your death. If all these sounds familiar, then you have experienced a hypnic jerk, also known as Sleep Twitch or Seep Start.

What does hypnic jerk mean?

Hypnic jerk is a phenomenon occurring in many people and refers to the state of jerking during sleep, as it is a muscle twitch which happens involuntarily while you are falling asleep, in particular during the “hypnagogic state of consciousness”. The person who experiences a hypnic jerk feels like at the rock bottom of a free-fall.

The hypnic jerk can last somewhere between a few seconds and a few minutes, however the experience varies based on the individual’s lifestyle, and medical history. In mild cases, the person doesn’t even feel or remembers the incident, and a partner usually lets them know of the problem, whereas in more serious forms, the person can wake up shaken and startled so much so that he/she cannot sleep again. In certain severe instances, the phenomenon can persist every night which disrupts with a normal sleep schedule and consequently the individual’s life and productivity.

What are the causes of hypnic jerk?

Hypnic jerk is a condition which does not happen as a result of a person’s actions and sometimes the individual is even unware that it happens. However, there has been some scientifically proven explanation of the causes for this phenomenon. Although not 100% certain, researchers from the American Academy of Sleep Medicine (AAOM) conclude that among others, hypnic jerk occurs when:

Due to a wrong and neglected sleep posture

If you tend to sleep uncomfortably for 6-8 hours, then this position may lead to a confusing state of mind in which the brain conceives this relaxing situation before going to bed, as similar to unsupported free-fall. Therefore, you are inclined to roll up your limbs to twitch awake with this sense of jerk shortly following this.

Taking medication

It is likely that if you have suffered a trauma, injury or undergone surgery or drug use, then you may be prone to hormonal imbalances and stress.
