Play an AI-generated podcast conversation about this lesson

What is the primary focus of most research on sleep and health?

The potential benefits of good sleep

The underlying architecture of sleep and its biological purpose

The negative consequences of poor or restricted sleep (correct)

The relationship between physical activity and sleep

What is the definition of 'sleep health' according to the passage?

Subjective satisfaction with sleep, sustained alertness during waking hours, appropriate timing, and adequate efficiency and duration

A deficit in the quantity or quality of sleep obtained versus the amount needed for optimal health

A pattern of sleep-wakefulness adapted to individual, social, and environmental demands that promotes adequate functioning of physical, mental, and social processes (correct)

The avoidance of problematic sleep and the absence/avoidance of illness, disease, and debilitating conditions

What does the passage suggest is the relationship between physical activity and sleep?

Physical activity is unrelated to the biological purpose of sleep

The relationship between physical activity and sleep is almost an expected outcome (correct)

The relationship between physical activity and sleep is unclear

Physical activity has no impact on sleep
