Review Questions
How does insomnia impact overall health and daily functioning?
Insomnia significantly affects overall health by leading to daytime fatigue, irritability, and reduced cognitive functioning. People with insomnia often struggle with concentration and memory, making it difficult to perform daily tasks effectively. The lack of restorative sleep can also contribute to mood disturbances like anxiety and depression, creating a cycle that exacerbates the insomnia itself.
What are some common causes of insomnia and how do they differ between acute and chronic forms?
Common causes of insomnia include stress, anxiety, depression, medical conditions like chronic pain, and lifestyle factors such as irregular sleep schedules or excessive screen time. Acute insomnia is usually triggered by specific events or situations such as stress from work or travel disruptions, while chronic insomnia is often associated with ongoing psychological or physiological conditions that require more comprehensive treatment strategies.
Evaluate the effectiveness of Cognitive Behavioral Therapy for Insomnia (CBT-I) compared to medication-based treatments.
Cognitive Behavioral Therapy for Insomnia (CBT-I) has been shown to be highly effective and often more sustainable than medication-based treatments. CBT-I addresses the underlying thoughts and behaviors that contribute to insomnia through techniques such as sleep restriction and cognitive restructuring. While medications may provide short-term relief, they can lead to dependency and do not address the root causes of insomnia. Studies indicate that individuals who undergo CBT-I experience longer-lasting improvements in sleep quality and overall well-being compared to those relying solely on medication.
