Improving sleep quality leads to better mental health: A meta-analysis of randomised controlled trials

The extent to which sleep is causally related to mental health is unclear. Our findings suggest that sleep is causally related to the experience of mental health difficulties.

⚡ This is an original paraphrased summary — not copied from the abstract. Full paper available at the source link below.

• 1 One way to test the causal link is to evaluate the extent to which interventions that improve sleep quality also improve mental health.
• 2 We conducted a meta-analysis of randomised controlled trials that reported the effects of an intervention that improved sleep on composite mental health, as well as on seven specific mental health difficulties.
• 3 65 trials comprising 72 interventions and N = 8608 participants were included.

Understanding this could lead to better treatments, improved diagnostics, or a deeper grasp of how the human body works — benefiting patient care globally.
