Nice. Mexico and Miami are great for the sun. Catch at least 20m at sunrise and sunset (sunrise is most important). Also midday sun for as much as you can tolerate without burning and your schedule allows. As much skin exposed as possible and never with sunglasses.

Your waking body temperature should be around >= 97.8 and raise to 98.6 or higher by midday. Low waking body temperature can be indicative of low thyroid function even with normal labs.

TSH range is too high, you want it under 2. T4 is converted to either T3 or rT3. You want the majority going to T3. So if you have low normal T3 and high normal rT3, your thyroid is not working well. Low T4 means less to convert to T3.
