Based on the best available evidence, how many hours of sleep are recommended for adults (18-65 yrs)?

Question

BlackTom AI · Accepted Answer

Considering sleep guidelines for adults aged 18-65, several options require evaluation.
Option 1: '5-6 hours' is generally considered below the recommended range for most adults, and chronic sleep within this window is linked to higher risks of cognitive and health issues.
Option 2: '7-9 hours' aligns with widely endorsed recommendations from major health organizations, which synthesize the best available evidence showing that this range supports optimal cognitive function, mood, and physical health for the majority of adults.
Option 3: '10+ hours' exceeds typical adult needs for most people and is not considered the standard recommendation; excessive sleep for extended periods can be associated with underlying health concerns or disrupted sleep patterns.
Option 4: 'There is no formal recommendation' contradicts established guidelines from authoritative bodies; a formal, evidence-based recommendation does exist and specifies a specific range.
In summary, the middle option matches the consensus from sleep science research and public health guidelines, while the other choices reflect oversleeping, undersleeping, or a misunderstanding of official guidance.
