Hypnic jerks, or sleep starts, are involuntary muscle contractions that some experience while falling asleep. They typically occur during the transition from wakefulness to a fully asleep state, specifically during stages one or two of sleep.
Along with hypnic jerks, people may experience a feeling of falling or tripping, a sensory flash, or a dream about falling. The intensity of the twitching can vary from strong enough to disrupt sleep to so mild that the individual may not notice. Although hypnic jerks can occur at any age, they are more prevalent among adults, possibly due to factors like caffeine consumption and increased stress levels, which are more common in adulthood.
Researchers consider physical and mental exhaustion as potential underlying factors for hypnic jerks. Extreme fatigue and high levels of stress and anxiety would hinder one’s ability to unwind before sleep. An alert mind is more susceptible to startle, increasing the likelihood that one would wake up when these involuntary muscle contractions occur. While hypnic jerks are generally harmless, persistent jerks during the daytime would require medical attention to determine if they stem from other neurological or sleep disorders.
While hypnic jerks are unpredictable and likely impossible to prevent entirely, a few lifestyle changes can help reduce their frequency. Establishing a regular bedtime and adopting a comfortable sleep posture will enhance the quality of sleep and thus reduce the occurrence of hypnic jerks. Other helpful activities include taking a warm bath and doing light stretches in the evening to relax muscles. And, of course, minimizing caffeine consumption and meditating will also help.
