sleep & caffeine, part 2

My friend Brent suggested that measuring caffeine intake by the ounces of the beverages consumed isn’t a good calculation, and he’s right. So, I went back and used this chart to determine the milligrams of caffeine per ounce depending on the beverage consumed. Here’s how the totals break down:

I found it interesting that while I drank about 35 more ounces of diet soda than coffee, coffee was clearly the major source of my caffeine intake.

Comparing the new set of data regarding my caffeine intake with the hours of sleep during the same time period, the chart looks a little different:

I gave the hours of sleep a multiplier of 100 so that it would be easier to compare them visually. There are definitely some points where the hours of sleep decrease and the milligrams of caffeine increase.

sleep & caffeine

I’ve been meaning to share this here. Back in January & February, I started using Daytum to keep track of the hours of sleep and ounces of caffeine I consumed each day. I’m not sure how much being aware of the data gathering influenced my decision-making, but it felt about like normal, so this is probably a decent snapshot.

You can see more visualization options and analysis on the Daytum page, if you are so inclined.

sleep patterns

On Friday night, I stayed up much later than I usually do. I’m not sure why — I wasn’t feeling well all evening and had decided to stay home rather than going out as planned. Somehow I managed to find things to entertain myself until 2am, although aside from the crossword puzzle, I can’t remember what those things were.

My cats — specifically Alex — woke me up at 7am. I was not happy, but I was just rested enough that by the time I fed them, I knew I wasn’t going back to sleep. In any case, the live feed of two of my favorite podcasts would be coming on around 9:30 or 10, and I didn’t want to miss the start. I knew that if I went back to sleep then, it would be for at least three more hours.

I was pretty sluggish for the rest of the day, but I kept on going. I figured I’d get to bed early that night and be back on my regular sleep schedule. However, by 6:30pm my body informed me that a nap was in order. So, I took a nap. A refreshing, four hour nap. So refreshing, in fact, that I could not make myself go back to sleep for the night.

Three hours later I was finally tired enough to go to bed. Again. The cats woke me up at 7am. this morning. Again.

I think they’re trying to get me on their sleep cycle, but until I’m allowed a siesta at work, it isn’t going to happen.

women in technology

Are you a women in the tech industry? If so, the Librarian In Black wants to hear from you.

The Librarian In Black commented on a series of articles in Business Week on women in technology. She’s looking for some feedback:

Maybe all the women are getting LIS or IS degrees instead…do those count as technology degrees? *wink* In all seriousness though, I would be interested in hearing (in the handy comments section of this post) what other women in technology out there think of this article. Do you think the technology world is gendered? Hell, do you think the technology aspect of librarianship is gendered? Is it egalitarian, or more so than the other industries that the article mentions?
