Have you ever felt a sudden **jerk** or a **falling sensation** right before you drift into **sleep**? These involuntary movements are called hypnic jerks, also known as **sleep starts**. They often happen when transitioning from **wakefulness** to **slumber**, and while experts are still researching their exact cause, they point to several common triggers.
During the process of **falling asleep**, your **muscles** completely relax. Sometimes, your **brain** misinterprets this relaxation as an actual fall, causing a sudden **twitch** or **jolt** throughout the body. Though these **jerks** are typically harmless, they can be disruptive, momentarily disturbing your **sleep quality**.
Common Triggers of Hypnic Jerks
According to Cleveland Clinic, certain lifestyle factors increase the likelihood of experiencing **hypnic jerks**. Elevated **stress**, consumption of **caffeine**, or excessive **physical exhaustion** can all contribute. Additional triggers include **sleep deprivation**, intense **exercise** close to bedtime, and high **nicotine** intake.
Prevalence
Research suggests that up to 75% of people experience these **sleep starts** at some point in their lives. Although they’re quite common, if **hypnic jerks** become frequent or severe, you may want to consider speaking with a healthcare professional to rule out other potential **sleep disorders**.
Tips to Reduce Hypnic Jerks
- Maintain a consistent **bedtime** and **wake-up** schedule, including weekends.
- Keep your bedroom temperature around **65–68°F** to promote better **sleep quality**.
- Avoid using **electronics** at least one hour before going to bed.
- Ensure your sleeping environment is dark and quiet.
- Limit **alcohol**, **nicotine**, and **caffeine** intake, particularly in the evening.
- Finish any vigorous **workout** at least 90 minutes before bed to allow your **heart rate** to normalize.
