Have you ever felt a sudden body jerk just as you’re about to drift off to sleep? This common phenomenon is called a hypnic jerk, and it’s perfectly normal.
According to sleep experts, this twitch happens when your body transitions from wakefulness to sleep. As your muscles relax, the brain may misinterpret this as a sign of falling, triggering a reflex muscle contraction to “wake you up” briefly.
Hypnic jerks are more common when you’re overtired, stressed, have consumed caffeine before bed, or sleep in an uncomfortable position. They are harmless and not a sign of any health problem.
Experts recommend calming bedtime habits to reduce them: avoid caffeinated drinks, lower stress levels, and create a comfortable sleep environment. If the jerks become too frequent and disturb your sleep, consult a doctor.
