Tinnitus and insomnia may be caused by physical fatigue, otitis media and insufficient blood supply to the brain. 1. Physical fatigue: staying up too late and excessive stress can lead to sleep deprivation and mental tension, causing nerve dysfunction in the brain, which can lead to tinnitus and insomnia. 2. otitis media: otitis media due to bacterial or fungal infections can cause patients to experience ear pain, hearing loss, tinnitus, occlusion in the ear and other symptoms, which affects the quality of sleep, thus causing tinnitus insomnia symptoms. 3. Insufficient blood supply to the brain: Insufficient blood supply to the brain will cause dysfunction of the brain, which will easily cause dizziness, headache attacks, and also tinnitus, accompanied by insomnia. Tinnitus and insomnia may also be caused by other reasons. When patients have symptoms of tinnitus and insomnia, they should go to the hospital for examination in time.
