Review Questions

• How does sleep deprivation impact cognitive functioning?
  • Sleep deprivation significantly impairs cognitive functioning by affecting attention, decision-making abilities, and memory retention. Without adequate sleep, the brain struggles to process information effectively, leading to slower reaction times and decreased problem-solving skills. This impairment can manifest in academic performance and daily activities, highlighting the importance of maintaining proper sleep hygiene for optimal cognitive health.
• Discuss the physiological effects of chronic sleep deprivation on the human body.
  • Chronic sleep deprivation leads to several detrimental physiological effects on the body. It can cause an increase in heart rate variability and elevated levels of stress hormones like cortisol. Additionally, prolonged lack of sleep can weaken the immune system, making individuals more susceptible to infections. These physiological changes underline the critical need for sufficient rest to support overall health and bodily functions.
• Evaluate the relationship between sleep deprivation and mental health disorders, considering both immediate and long-term effects.
  • The relationship between sleep deprivation and mental health disorders is complex and multifaceted. Immediate effects of sleep loss can include mood swings, irritability, and heightened anxiety levels. Over time, chronic sleep deprivation can contribute to the development or exacerbation of conditions like depression and anxiety disorders. Understanding this relationship is crucial for developing effective treatment strategies that address both sleep hygiene and mental health care for those affected.
