This is just my hunch, but I think temperature treatment is the wrong conclusion to this finding. When someone is sick with a virus and has a fever, people suggest taking ibuprofen to lower the fever effectively masking the symptoms, but that does nothing to address the underlying cause.

I think this finding can be helpful is trying to find other ways to reduce inflammation in the body (assuming inflammation is driving the temperature increase) Interventions like diet changes could lead to both less inflammation and less depression.
