Final answer:
The correct statement regarding changes in sleep with aging is that REM sleep decreases. Sleep patterns change throughout our lives, with deep and REM sleep reducing as we grow older, and sleep may become more fragmented.
Step-by-step explanation:
Among the options provided, the true statement about the changes that occur in our sleep as we age is B) REM sleep decreases. The amount of sleep we need changes throughout our lives; infants may sleep up to 16 hours a day, but by the time we are 65 years old, we may sleep fewer than 7 hours. Additionally, as we age, sleep can become more fragmented, and there are changes in the structure of sleep, including a reduction in slow-wave (deep) sleep and REM sleep. It is a misconception that sleep duration increases or that nightmares decrease with age. Sleep problems can become more common as we get older, contributing to a more fragmented sleep pattern.
