Review Questions

• How do stimulants influence the occurrence of insomnia?
  • Stimulants, such as caffeine and nicotine, directly impact the body's ability to fall asleep and stay asleep. They stimulate the central nervous system, increasing alertness and making it harder for individuals to wind down at night. The consumption of these substances, particularly in the hours leading up to bedtime, can disrupt the body's natural sleep cycle and contribute to both acute and chronic insomnia.
• Discuss the relationship between insomnia and mental health conditions such as anxiety and depression.
  • Insomnia is often interconnected with mental health issues like anxiety and depression. Individuals suffering from anxiety may find it difficult to relax enough to fall asleep due to racing thoughts or excessive worry. Conversely, those with depression may experience disruptions in their sleep patterns. The bidirectional relationship means that insomnia can exacerbate mental health issues while also being a symptom of them, creating a challenging cycle for those affected.
• Evaluate the effectiveness of cognitive behavioral therapy (CBT) in treating insomnia compared to pharmacological approaches.
  • Cognitive behavioral therapy (CBT) has been shown to be an effective treatment for insomnia by addressing underlying thoughts and behaviors that contribute to sleep difficulties. Unlike pharmacological approaches that may provide temporary relief but come with side effects or dependency risks, CBT focuses on long-term solutions by teaching coping strategies and promoting healthier sleep habits. Studies indicate that CBT not only improves sleep quality but also provides lasting benefits compared to medications alone, making it a preferred option for many healthcare providers.
