Verified step by step guidance

1. Understand the importance of sleep: Sleep is a critical component of overall health and wellness. It plays a vital role in cognitive function, memory consolidation, immune system support, and emotional regulation. Adults typically need 7-9 hours of sleep per night for optimal functioning.
2. Analyze Samantha's sleep pattern: Samantha is averaging 5 hours of sleep per night, which is significantly below the recommended amount. Chronic sleep deprivation can lead to various negative outcomes, including impaired cognitive function, reduced academic performance, and weakened immune response.
3. Evaluate the options provided: Review each option and assess its alignment with the effects of sleep deprivation. For example, a strengthened immune system and increased productivity are unlikely outcomes of insufficient sleep, as sleep deprivation typically weakens the immune system and reduces productivity.
4. Focus on the correct outcome: Research shows that sleep deprivation is strongly associated with a decrease in cognitive function, including difficulties with memory, attention, and problem-solving. This can directly impact academic performance, making this the most plausible outcome for Samantha.
5. Conclude with the correct answer: Based on the evidence and understanding of sleep's role in health and wellness, the correct answer is 'A decrease in cognitive function and academic performance.' This aligns with the well-documented effects of chronic sleep deprivation.
