Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or waking up too early, leading to unrefreshing or non-restorative sleep. It can significantly impact daily functioning and quality of life, often affecting mood, energy levels, and cognitive performance. Insomnia can be acute or chronic and may arise from various causes, including stress, anxiety, medical conditions, or lifestyle factors.

Review Questions

• What are some common behavioral and environmental factors that contribute to insomnia?
  • Common behavioral factors that contribute to insomnia include irregular sleep schedules, excessive screen time before bed, and high caffeine consumption. Environmental factors such as noise, uncomfortable temperatures, and poor sleep hygiene practices also play a significant role. These elements can disrupt the body's natural circadian rhythm and hinder the ability to fall asleep or stay asleep throughout the night.
• Discuss the differences between acute insomnia and chronic insomnia in terms of duration and potential causes.
  • Acute insomnia is typically short-term and lasts for a few days or weeks, often triggered by specific stressors such as major life changes or temporary anxiety. In contrast, chronic insomnia persists for at least three times a week over a period of three months or longer. Chronic insomnia is frequently associated with underlying health issues such as anxiety disorders, depression, or chronic pain conditions, making it more complex and difficult to treat effectively.
• Evaluate the effectiveness of cognitive behavioral therapy for insomnia compared to traditional medication treatments.
  • Cognitive behavioral therapy for insomnia (CBT-I) has been shown to be highly effective in treating insomnia by addressing underlying thoughts and behaviors that disrupt sleep patterns. Unlike traditional medication treatments that may offer temporary relief but come with risks of dependency and side effects, CBT-I focuses on long-term solutions that help individuals develop healthier sleep habits. Research indicates that CBT-I not only reduces symptoms of insomnia but also improves overall sleep quality without the adverse effects associated with pharmacological interventions.
