Can drinking coffee affect sleep and cause eyelid jump?

Hello, the eyelid is beating because there is a thin layer of muscle inside the eyelid, called orbicularis oculi muscle. Due to the temporary insufficient blood supply to the eye and unbalanced nerve conduction, a certain part of the orbicularis oculi muscle fiber is affected by this, which causes it to contract suddenly and repeatedly, and saccades may occur. Medically, it is called eyelid tremor or eyelid spasm. Traditional Chinese medicine believes that eyelid pulsation is caused by diseases such as heart and spleen damage, heart and spleen deficiency or liver and spleen blood deficiency, wind-induced wind for a long time, wind deficiency and internal movement.
