Final answer:
Chronic sleep deprivation is true to promote obesity and impair memory due to its effects on cognitive function and physiological health, including hormonal imbalances that can contribute to weight gain.
Step-by-step explanation:
The statement that chronic sleep deprivation is likely to promote obesity and impair memory is True. Sleep plays a critical role in maintaining various aspects of cognitive function, one of which is memory consolidation. Without adequate sleep, our ability to understand, consolidate, and recall information is compromised.
On the physical side, lack of sleep can lead to hormonal imbalances that contribute to weight gain. Obesity is linked to numerous health issues, including insulin resistance and type 2 diabetes. Therefore, the negative consequences of sleep deprivation extend far beyond feeling tired, impacting both mental alertness and physiological health.
