Muscle twitches during sleep may result from physical fatigue accumulated during the day or from heightened mental stress. If an individual has a sleep disorder, it may cause localized neural hyperactivity, leading to such twitching. It is important to address unhealthy lifestyle habits, reduce stress, and ensure adequate rest.
