The level, or volume, of Tinnitus can fluctuate based on any number of factors. Stress, food allergies, and blood pressure could have an effect on you. You didn’t mention when yours gets worse, so I’ll elaborate on several instances.
I noticed that my tinnitus gets worse at night when I try to sleep. That might very well be because I’m paying more attention to it. During the day, I’ve learned to allow my activities to overpower my thought process and I simply don’t pay attention to it. But it’s still there; it just doesn’t bother me as much when I’m actively doing other things.
You didn’t say what kind of tinnitus you have, but people with pulsating tinnitus say it gets worse when they lie down. This can be a drag when trying to fall asleep.
If you notice your tinnitus is more like a pulsating kind, it may be Objective Tinnitus, caused either by blood vessels making pulsating sounds or by muscle movements. Lying down is known to make this type worse. You should get this checked out by a cardiologist if that’s what you have, since you could have plaque buildup in your blood vessels.
Mine is not pulsating, it’s Subjective Tinnitus. That’s a perception of sound produced by the brain. I’ve learned to ignore it when I’m falling asleep. I used to try using noise machines, but they never worked ⎯ at least not for me. Some people swear by them, so it’s worth trying. They help distract your attention from the tinnitus.
It’s helpful to discover what activities you are doing that may help or hinder the level of your tinnitus. Keep a log of what you’re doing each day and how you feel. Keep a record of the foods you are eating. Some foods might be causing it to get worse. I found too much coffee makes it worse, but everyone is different. You need to find out for yourself, and keeping a log helps with doing that.
Also, include your stress level in your log. I discovered stress is the strongest cause of my loudness. This might be true for you too.
After you have created a log of your activities, foods you eat everyday, and your stress level, you should have a better impression of what changes you need to make in your life to avoid a high volume of your tinnitus.
