Why Hypnic Jerks Happen: The Nervous System’s Mixed Signals
According to experts like Rafael Pelayo from the Stanford Sleep Medicine Center, hypnic jerks occur due to a miscommunication between wakeful and sleepy parts of the nervous system. When we’re sleep-deprived, our body may skip critical stages of sleep, jumping straight into REM. This quick transition, or “misfire,” results in the hypnic jerk—a clear sign from the body that sleep is urgently needed. While the exact causes of hypnic jerks are not fully understood, factors like stress, fatigue, or attempting to stay awake when exhausted can increase their likelihood.
Are Hypnic Jerks Dangerous? How to Reduce Their Frequency
Though they may seem alarming, hypnic jerks are harmless. However, if they’re frequent, it may be a sign that you need more sleep. For some, these jerks can also happen when they’re trying to stay awake in situations like meetings or classes. To prevent them, make sure you get seven to nine hours of sleep each night and try simple tips like focusing on the speaker, making eye contact, or drinking coffee to stay alert when needed. While hypnic jerks can be unsettling, understanding them can help ease anxiety so you can get the rest your body needs.
