What We Know About Dreaming's Link to 83 Diseases

Researchers found a connection between dream patterns and 83 diseases, according to a report from ZME Science. The outlet's headline cites the figure directly, but the version of the report available for this piece did not include the study's authors, funding source, or sample size.

What did ZME Science report about dreaming and disease?

ZME Science's report ties dreaming to a broad set of health conditions, putting the number at 83 diseases. The outlet frames dreaming as a signal worth tracking alongside known risk factors. The material reviewed for this article did not include the full text of the underlying study or a list naming each of the 83 conditions.

How many diseases are linked, and in what way?

The figure of 83 diseases comes from ZME Science's own headline and summary. It is not broken down here by category — cardiovascular, neurological, metabolic, or otherwise — because that breakdown was not present in the source material available for this report. Readers who want the specific disease list should consult ZME Science's original article directly.

What information is missing from the current report?

Several basic facts are not available in the version of the ZME Science report reviewed for this piece. There is no journal name, no research institution, and no date range for when dream data were collected. It is also unclear whether the findings rely on self-reported dream recall, sleep-lab monitoring, or another data source. Those gaps matter: the method researchers use to measure dreaming can shape how strong, or how reliable, any disease association turns out to be.

Has the underlying study been published or peer-reviewed?

That detail was not specified in the source material available for this report. Peer review status affects how much weight a finding should carry, since unreviewed results have not been checked by outside experts for methodology or statistical soundness. Readers following this story should look for confirmation of publication and peer-review status in ZME Science's full account or in any journal citation the outlet provides.

What should readers do until more details emerge?

Treat the 83-disease figure as a reported claim from a single outlet until more of the underlying study is public. Check ZME Science's original article for the full list of conditions, the research team's identity, and the journal of publication. Association between two factors — dreaming and disease, in this case — does not by itself establish that one causes the other, and the current report does not specify that researchers made that distinction.
