Review Questions

• How does sleep deprivation affect children's cognitive function and behavior?
  • Sleep deprivation negatively impacts children's cognitive function by impairing memory, attention, and decision-making abilities. It can also lead to behavioral problems such as increased irritability, mood swings, and difficulty in managing emotions. This cognitive decline may hinder their academic performance and social interactions, further exacerbating issues related to childhood obesity.
• Discuss the relationship between sleep deprivation and childhood obesity from a physiological perspective.
  • From a physiological perspective, sleep deprivation disrupts the balance of hormones that regulate appetite, particularly ghrelin and leptin. Ghrelin levels increase while leptin levels decrease, leading to heightened feelings of hunger and decreased satiety. This hormonal imbalance may drive children to overeat and make poor food choices, increasing the risk of obesity.
• Evaluate the long-term implications of sleep deprivation during childhood on future health outcomes.
  • The long-term implications of sleep deprivation during childhood can include a higher risk of developing chronic health conditions such as obesity, diabetes, and cardiovascular diseases in adulthood. Additionally, ongoing cognitive deficits can lead to poor academic performance and reduced career opportunities. Addressing sleep deprivation early can have a significant impact on improving not only immediate well-being but also long-term health outcomes.
