Unscramble the Blue Letters

And it tunrs out that there are implications for understanding how sleep is structured in this way. Let's take someone who typically goes to bed at 10pm, and they wake up at 6am, so they have an eight-hour sleep window. But this morning, they have to wake up early for an early morning meeting, or they want to get a jump start on the day to get to the gym. And as a consequence, they have to wake up at 4am in the morning, rather than 6am in the morning. How much sleep have they actually lost? Two hours out of an eight-hour nhgit of sleep means that they've lost 25 pnceret of their sleep. Well, yes and no. They have lost 25 percent of all of their sleep, but because REM seelp comes mostly in the second half of the night and particularly in those last few hours, they may have lost perhaps 50, 60, maybe even 70 percent of all of their REM sleep.

Original Text

And it turns out that there are implications for understanding how sleep is structured in this way. Let's take someone who typically goes to bed at 10pm, and they wake up at 6am, so they have an eight-hour sleep window. But this morning, they have to wake up early for an early morning meeting, or they want to get a jump start on the day to get to the gym. And as a consequence, they have to wake up at 4am in the morning, rather than 6am in the morning. How much sleep have they actually lost? Two hours out of an eight-hour night of sleep means that they've lost 25 percent of their sleep. Well, yes and no. They have lost 25 percent of all of their sleep, but because REM sleep comes mostly in the second half of the night and particularly in those last few hours, they may have lost perhaps 50, 60, maybe even 70 percent of all of their REM sleep.
