We're sorry, but we are unable to create a summary of the requested article. The search results only contain a link to the article titled "Regulate worker heat exposure in global trade" from the journal Science (January 2026), but the content of the article itself is not available in the provided sources. We only have the title and bibliographic data, but not the text of the article needed to create a factual summary. If you wanted, we could create a summary based on the available information on worker heat load regulation from other sources in our results, but that would not be a summary of the specific article you requested.
