New Study Reveals That Daytime Naps May Be a Sign of Serious Health Problems

A JAMA Network study of nearly 1,300 patients found that longer and more frequent daytime naps were linked to higher all-cause mortality risk.

Short naps did not show a significant increase in mortality risk, suggesting timing and duration matter.

Researchers say excessive napping may be a warning sign of underlying metabolic, cardiovascular, or sleep-related problems such as sleep apnea.

The findings do not prove naps cause harm, but they highlight nap patterns as a possible marker of overall health.
