Final answer:
Children tend to experience more deep sleep than older adults because deep sleep is essential for the body to repair itself and for growth, which is higher in children. Older adults have less deep sleep due to changes in sleep architecture with age.
Step-by-step explanation:
The answer to the question of who tends to experience more deep sleep children or older adults is A) Children. Deep sleep, also known as slow-wave sleep, is crucial for many aspects of health and cognitive functioning. It is in deep sleep that the body repairs itself and that growth and development occur. Studies have shown that children spend a higher proportion of their sleep time in deep sleep compared to older adults, whose sleep patterns tend to include less deep sleep as they age.
Therefore, it is children who experience more deep sleep than older adults, reflecting the growing and developmental needs of youth. Additionally, due to the changes in sleep architecture throughout the lifespan, an older adult's sleep pattern will have more light sleep and awakenings, leading to less overall deep sleep.
