Usually, there are several reasons for frequent waking up in bed: First, poor sleep quality, due to plant dysfunction or excessive psychological or mental stress, which leads to prolongation of the short sleep phase and shortening of the deep sleep phase, resulting in frequent waking up when entering the short sleep phase. Secondly, if there is a previous cerebrovascular disease, such as the sequelae of stroke, cerebral infarction or cerebral hemorrhage, you may wake up frequently during transient cerebral ischemic attack. Thirdly, if sleep apnea syndrome occurs during sleep, it may also cause waking up during sleep, and if there is a transient cardiovascular blood supply insufficiency during sleep, it may also cause waking up frequently during sleep.
