The Mystery of Hypnic Jerks: Why Do We Twitch When Falling Asleep?

Hypnic Jerks: Why Do We Twitch as We Fall Asleep? Many people experience hypnic jerks—those sudden, involuntary muscle twitches that occur just as we're drifting off to sleep. While the exact cause isn't fully understood, several factors are known to contribute. Recent research suggests that anxiety, caffeine, and certain medications, such as selective serotonin reuptake inhibitors (SSRIs), can increase the likelihood of experiencing these jerks. One TikTok video by Startitup, a Slovak news outlet, highlights this common phenomenon, sparking a discussion about the causes and experiences among viewers. "The sudden jolt feels like you're falling," explains the video's presenter, "and your body reacts instinctively." This description resonates with many who have experienced the sudden startle reflex. The video also emphasizes the role of stress and caffeine in exacerbating the issue. While hypnic jerks are generally harmless, understanding their potential causes can help individuals manage their sleep quality. For example, reducing caffeine intake before bed or managing anxiety through relaxation techniques might help reduce the frequency of these nighttime twitches. The video's popularity underscores the widespread nature of this experience and the public's interest in understanding sleep-related phenomena.
