What percentage of total sleep is comprised of REM sleep?

Explanation:
Rapid Eye Movement (REM) sleep typically constitutes about 20-25% of total sleep in healthy adults. This stage of sleep is critical for various functions, including memory consolidation, emotional processing, and brain development. The percentage can vary depending on different factors such as age, sleep patterns, and overall health, but the standard percentage acknowledged in sleep research reflects that REM sleep usually falls within this range. Therefore, identifying 25% as the correct answer aligns well with established sleep science findings.
