It’s a widely known fact that some people twitch and jump suddenly as they are falling asleep, and these twitches are known as hypnologic mycologist, where “hypnologic” refers to sleep and “mycologist” refers to any type of involuntary muscle spasm Twitching generally occurs during the early
Stages of very light sleep as a person is drifting off to sleep, and for this reason such spasms are also called “sleep starts”.
While it’s not known exactly what causes the twitches, they are the result of sudden muscle contractions that some scientists believe are related to anxiety or caused by a faint stimulus, such as a noise or a touch Vivid dreaming in the early stages of sleep may also cause twitching (dreaming about falling, for example, often results in twitching), while muscle fatigue can be another contributory factor.
Other scientists believe that some forms of twitching are caused by a disruption of two particular neurotransmitters in the brain: serotonin, which constricts blood vessels and induces sleep, and gamma-aminobutyic acid, which helps to control the muscles It’s thought that these neurotransmitters get disrupted while the sleepy brain ceases to control the body’s motor functions, resulting in twitching.
While cyclonic jerks can be a symptom of a disease such as multiple sclerosis or Parkinson’s and Alzheimer’s disease, they are generally harmless and common in many people On most occasions, the person experiencing the twitching is unaware that it’s happening and doesn’t remember it afterward.
