Efforts to improve sleep quality focus on optimizing both the physical environment and personal relaxation habits. Recommendations include maintaining specific temperatures and humidity levels, using blackout curtains to control light, and minimizing noise to ensure deep rest.

Beyond environmental adjustments, specific techniques have been suggested to combat insomnia and stress. These include using scents, music, or warm lighting to create a relaxing atmosphere. Additionally, the Tokyo Metropolitan Police Department’s Disaster Management Division suggests a five-minute progressive muscle relaxation method, which involves tensing and slowly releasing muscles while breathing deeply to transition the body into a state suitable for sleep.
