3. Individuals with nightmares showed faster epigenetic aging.
4. Biological aging explained 39% of the link between nightmares and premature mortality.
5. Study suggests further investigation into treating nightmares to reduce mortality risk and slow biological aging.
6. Emphasizes the need for clinicians to consider frequent nightmares in adults as a potential marker of underlying health risk.
7. Large sample size and long-term follow-up strength of the findings. 8. Combining symptom reporting with biological data valuable for assessing long-term outcomes.
