Sleep Study: What They Study

[woodwardiocom]

For those who've never done one, here's the data they gathered in my sleep study:

• Heartbeat.
• Breathing.
• Whether my eyes were rapidly moving.
• Whether I was grinding my teeth.
• Whether my legs were twitching.
• Blood oxygen levels.
• Nasal intake/outgo.
• There was a second doohickey on my upper lip . . . possibly to measure CO₂ levels?
• Brainwaves.
• Whatever random noises I might be making.
• And, of course, a seven-hour video of me sleeping.

That's a lot of data to crunch . . .

PS: And yes, another person counts, whether in the same bed, across the room, or breathing and making noise down the hall. We aren't all cut out for cuddling or even social living during our sleep time.
