Review Questions

• How do the symptoms of insomnia influence daily life and cognitive functioning?
  • The symptoms of insomnia lead to significant impacts on daily life by causing excessive daytime fatigue, irritability, and difficulty concentrating. This lack of restorative sleep impairs cognitive functions such as memory retention, decision-making skills, and overall mental clarity. As a result, individuals with insomnia often struggle to perform at their best in academic or professional settings due to diminished focus and increased mistakes.
• Discuss the potential relationships between insomnia and other psychological conditions.
  • Insomnia is often intertwined with various psychological conditions like anxiety and depression. People suffering from anxiety may find it difficult to relax at night, leading to difficulties in falling asleep. Conversely, chronic insomnia can exacerbate feelings of depression by contributing to fatigue and hopelessness. The relationship creates a cycle where mental health issues disrupt sleep, which in turn worsens those mental health issues.
• Evaluate the effectiveness of cognitive behavioral therapy for insomnia compared to pharmacological treatments.
  • Cognitive Behavioral Therapy for Insomnia (CBT-I) has been shown to be highly effective as a long-term solution for treating insomnia. It focuses on changing behaviors and thoughts that contribute to sleep problems. While pharmacological treatments may provide quicker relief by inducing sleep, they often come with side effects and risks of dependency. Studies suggest that CBT-I not only addresses the symptoms but also tackles underlying issues related to sleep disturbances, making it a more sustainable approach for many individuals.
