Harmless muscle twitches are muscle contractions that are brought on by thirst, nutritional deficiency, muscle fatigue, or anxiety. Too much use of caffeine or prolonged use of drugs such as diuretics, corticosteroids, or estrogen might also be causal factors. Such instinctive contractions often happen in the eyelids or calf muscles.
