During sleep, your body enters a period of physical recovery. However, resting muscles can still experience involuntary contractions when neuromuscular balance is off: Neuromuscular Irritability: When electrolyte levels fluctuate or fatigue sets in, motor nerves can fire spontaneous, hyperactive signals to muscle fibers.
