Tinnitus can cause insomnia because it often causes irritability in patients. In clinical work, we will encounter some patients who come and tell the doctor first of all that they are very upset today because they always hear a kind of ringing sound inside their ears, non-stop with a possible machine-like ringing sound, which is so noisy that they cannot sleep. The situation can cause the patient to feel very uncomfortable and unpleasant, so it can cause the patient to sleep poorly. Therefore, tinnitus and sleep are causally related to each other. Long-term poor sleep can lead to tinnitus, which may worsen, and long-term tinnitus can cause irritability and restlessness. Therefore, the relationship between tinnitus and sleep is complementary. In clinical work, we may encounter this situation, that is, if we solve the problem of sleep, the tinnitus may also slowly improve.
