I'm doing some experiments on exercising and tinnitus and here is what I found. This probably only applies to people that have anxiety in general or anxiety is making their tinnitus worst. I tried doing light exercise and it has done practically nothing for me. Doing light exercise, 30 min per day of aerobic does help me sleep though where being inactive with anxiety and tinnitus gets me insomnia. Yesterday I was feeling pretty bad. At 4pm I did an all out sprint around my block. Probably 3 minutes or so. I got home and was exhausted, my heart rate going. I sat back down. An hour later I still had my tinnitus, but I felt good. Its almost like my brain got rewired to feel good instead of bad. At 7pm I ran the same sprint. By 7:30pm again I could still hear my tinnitus but it didn't bother me for the rest of the night. Its almost like I was on clonazepam, but I wasn't. Sleeping was a breeze with the tinnitus. The next morning I woke up and my tinnitus was back at baseline and hardly noticeable. 6 hours into the day and I'm still good. I'm not sure how long this will last, but so far so good. I'm going to keep trying this and see if I can reproduce the same results everyday. I think there is something to tiring the body to the point of exhaustion even for only a small time that is helpful.
