Dr. Kui Yongjian
A sudden twitch during sleep is generally caused by adverse psychological factors such as excessive mental stress, high pressure, or overwork. Additionally, it may be related to calcium ion deficiency, which is commonly seen in middle-aged and elderly patients or menopausal women. Excessive physical activity before bedtime can also lead to reflexive, involuntary muscle twitches during sleep, as local muscles suddenly relax.
