I have had problems with my thyroid on and off now for 18 years. It has vacillated between being hyper or hypo. My first question to you is - Is your hyperthyroidism under control? Are you being treated for this?
I've been told that exercise can affect thyroid function. Keep tabs on your heart rate. I do this by wearing a heart rate monitor when I swim. If you are concerned about your intensity, the heart rate monitor is a great tool for letting you know when you are pushing it too hard.
