TS Epsisode 20: The Real Reason Your TSH Goes Up in Winter
Show: Thyroid Answers Podcast
Every winter, TSH rises—but that doesn't mean thyroid failure. Dr Eric Balcavage explains how photoperiod, melatonin, and circannual rhythms alter TRH → TSH → T3 and why seasonal adaptation is often misdiagnosed as hypothyroidism.
In this episode, you'll learn:
✅ How shorter days and colder temperatures reset the hypothalamic–pituitary–thyroid axis
✅ Why macro-TSH raises lab TSH without true hypothyroidism
✅ How both conventional and functional models misread winter physiology
✅ Five ways to align with your seasonal thyroid rhythm (light, rest, minerals, movement, patience)
