This evidence suggests that Neiyanggong practice during chemotherapy may be associated with reduced fatigue and better sleep, though larger multi-center studies would clarify whether these benefits persist after treatment ends.

Poor sleep quality appears linked to tension-type headache and is more strongly associated with depression than with headache burden itself.

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.

Temporary descent to lower altitude may reduce oxygen desaturation and sleep breathing disruption in people living at moderate altitudes, suggesting that clinical sleep assessments performed at lower altitudes could underestimate the severity of sleep-disordered breathing.

In adults with sleep apnea and existing heart disease, central body fat distribution (measured by waist-to-height ratio) was more consistently linked to recurrent cardiovascular events than standard BMI categories.

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.

Improving sleep in children and adolescents may be associated with lower anxiety symptoms and reduced risk of anxiety disorders developing, and sleep is a practical prevention target in pediatric mental health.

Tai Chi, yoga, and combined exercise may be linked to modest sleep improvements in breast cancer survivors, with moderate-dose protocols potentially offering the greatest benefit.

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