If you can’t sleep when there is a little sound, consider neurasthenia caused, that is, the patient’s sleep is relatively shallow. The normal sleep is divided into deep sleep and light sleep, and the cerebral cortex is active during light sleep, so it is easy to be awakened by some sounds. In deep sleep period, patients sleep more deeply and are not easily stimulated and awakened by other sounds. If the patient can’t sleep with a little sound when sleeping, it belongs to the shallow sleep period which is longer and will affect the sleep quality of the patient. Only during the deep sleep period, the person’s body and brain will be fully restored. So if one wakes up with a little sound when sleeping, one can take oral medications to improve sleep, such as tranquilizer oral liquid and dexzopiclone, to deepen sleep.
