The symptom of feeling inexplicably uncomfortable while sleeping is known as restless legs syndrome in medical clinical practice. The cause of this symptom is not very clear, but may be related to the disturbance of plant nerves, mental state, emotional well-being, and excessive daytime exertion.

You should keep a regular life, not stay up late, have a good mood, adjust your diet and exercise properly.
