Study Summary
Insomnia is a common sleep problem affecting many people at various stages of life. Fortunately, there are well-researched behavioural methods that can help improve sleep without relying solely on medication.
What They Did
This review article by Markwald et al., published in ACSMs Health Fit J. in 2019, explored behavioural strategies for addressing insomnia, covering individuals experiencing both chronic and short-term insomnia, including examples from American and older adult populations.
What They Found
The authors highlighted cognitive-behavioural therapy for insomnia (CBT-I) as a highly effective and well-documented treatment, superior to sleeping pills. They also identified exercise—especially aerobic and resistance types—as beneficial in improving sleep and reducing insomnia risk. Behavioural recommendations such as maintaining good sleep hygiene, applying sleep restriction, stimulus control techniques, and practising relaxation are encouraged. Exercise appears to enhance sleep partly through body temperature regulation and anxiety reduction, with the timing and type of exercise influencing sleep quality. Integrating these sleep habits and exercise routines may help resolve insomnia symptoms before consulting a clinician.
Why It Matters
These findings reinforce that non-pharmacological behavioural interventions, including structured therapy and physical activity, can play a vital role in managing insomnia. They offer practical, accessible options that many can apply themselves to improve sleep health.
My Clinical Insight
From a clinical perspective, encouraging patients to adopt CBT-I principles and regular exercise provides valuable tools to tackle insomnia sustainably. The nuanced impact of exercise type and timing on sleep quality means personalised advice can optimise results. This approach supports patients in regaining control over their sleep without immediate recourse to medication.
