Exercise may improve aerobic fitness, lower inflammation, and reduce depression in dialysis patients, but evidence quality is limited and benefits vary by exercise type.

A brief virtual education program on andropause appears to be linked with meaningful improvements in sleep and general health among retired men, though the effect is moderate and durability beyond two months is unknown.

A brief self-guided mobile intervention may offer modest complementary stress reduction alongside antidepressant therapy in early depression treatment, though larger studies are needed to confirm the effect and understand which users benefit most.

A 6-week mindfulness program may be linked to improved optimism and mindfulness in breast cancer survivors, though the effect on broader social support remains unclear.

Brief mindfulness or narrative interventions may boost well-being in nurse leaders over 1–2 weeks, but whether resilience gains last or require reinforcement remains unclear.

Mindfulness-based interventions may reduce anxiety and depression partly by lowering perceived stress, with early stress reduction potentially signaling who will benefit most.

Web-based CBTi may be more effective than other formats for adolescent insomnia, suggesting school and primary-care settings could expand access by prioritizing digital delivery over in-person or app-based alternatives.

Higher sense of purpose in life may be associated with meaningfully lower mortality risk, an association that persists even after accounting for depression and major health behaviors, though the full mechanism remains unclear.

Delayed school start times may help adolescents sleep longer, but the link to reduced depression appears modest and warrants more rigorous research.
