Answer to your Health Question

Question: What are the reasons or causes that can make my body twitch & jerk (spasm) while I'm falling asleep? Sometimes I will continue to do this during the night (so my partner says) but most of the time it's just while my body falls asleep and yes it happens every night. I have Meniere's disease, could this be a cause? Thank you for your time. Ivy

Answer: Dear Ivy,

The symptoms you mention are similar to those of Hypnic jerks. A hypnic jerk is an involuntary muscle twitch which often occurs during the transition from wakefulness to sleep. It is usually described as an electric shock or falling sensation, and can cause movement of the body in bed. Hypnic jerks are completely normal, and are experienced by most people, especially when over-tired or sleeping uncomfortably. The exact cause of the sudden jerks is not clear.
