Many people with thyroid conditions struggle with temperature regulation, with complaints of cold intolerance as well as heat intolerance. In the thick of summer here in the UK at the moment, I am reliving the situation that once again, I get hot and stay hot so much easier than others I know! This newsletter explains why this happens. I’ve included both written and a video explanation!

It also includes a blend of thyroid articles, news, personal updates, discounts and more.

This Week’s Topic: Heat Intolerance and Thyroid Disease

As well as cold intolerance, which is where you feel particularly reactive to cold temperatures, heat intolerance can be a symptom of thyroid disease, too. This symptom can also be made worse by rising temperatures outside

If you feel easily hot, especially compared to others around you, have hot flushes and do not cope well in hot weather, this may suggest that you experience heat intolerance.

This can be linked to hypothyroidism for a few reasons.
