Podcast: Subscribe: Show Notes on 2B-Alert The US Army commissioned a study to find the optimal amount and timing of caffeine consumption for soldiers to maintain peak alertness. I have never been more proud of my tax dollars in all my life. Now, the 2B-Alert tool has been released in a web application accessible to the public. While this is a very fun tool, its use should be considered carefully. Should we really expect that the populace be placed on stimulants to maintain peak performance? Should expectations be adjusted? Or are there other options for a healthy balance of work, sleep, caffeine, and life? Sometimes, you just need to smile. Interesting Engineering article from 2019 announcing the public availability of 2B-Alert. Original research paper publication from the Journal of Sleep Research detailing the study and its conclusions. The 2B-Alert web tool. In order to use it, you must register for an account. 2B-Alert Episode Transcript View full episode transcript Welcome to the Data Science Ethics Podcast.

Lexy: Hello everyone and welcome back to the data science ethics podcast. Marie: And caffeine. Lexy: So excited. The article that we are going to link this time is a study that was conducted by the U s army to try to identify an algorithm that could predict the optimal quantity and timing of caffeine for service men and women to stay at their peak alertness despite their lack of sleep. And now they have released this tool as a web tool to the public. I am so excited about this. We will link to it. What they did is they studied the timing and the quantity of caffeine across a range of beverages to determine the impairment level of those consuming it. So how could that caffeine help reduce their impairment versus just being sleep deprived and struggling through it? Lexy: Yup. They do have the ability to predict the impairment level if you are not sleep deprived. Correct. The only factors that this tool takes into consideration is the amount and timing of your sleep and the amount of caffeine that you consume. Lexy: We played around with this. Marie: Of course we did. Lexy: Because of course we did and we had some really interesting conclusions coming out of our experimentation with this tool and of course some questions. Marie: Absolutely. Lexy: The first thing to note is if you do try this tool, the alertness level that it shows you is actually an alertness impairment and it compares your alertness impairment to a blood alcohol content of 0. So if you pass that line, you basically are acting as impaired as if you had been consuming alcohol. All of the above. And we found that if you put it in your naps, it seems to help. If you put it in your caffeine, obviously it shows a decrease temporarily. So over the course of the day it has this kind of sine wave curve going on where earlier in the day it shows more impairment and then it drops and then it comes back and so forth. This is very interesting stuff. And of course because they did this based on the military, we have a lot of questions as to how applicable it is. Marie: And so this just goes back to how the algorithm was trained in the population that they were training on. Yes. So when it comes to people that are in the military, they usually have more physical activity in terms of their normal job requirements versus what maybe a civilian would normally have. Their age is usually going to be lower versus what maybe an average civilian is going to be. So those are things to keep in mind as you look at this tool that this could be skewed a little bit towards certain populations. Lexy: Absolutely. The other thing that came to mind is not only the activity level but also the nutrition in the military. They are given specific types of nutrients. They are given a different balance of nutrients. I mean the human body is a complex system. Marie: Yeah. And apparently they also have access to something called military energy gum. Lexy: I want to know what that is. Marie: And another thing that Lexy was thinking about as she was looking at her examples is that she knows that she needs caffeine because otherwise what happens, Lexy? Lexy: Headaches and a lot of grumpiness. Just to maintain her current caffeine dosage? Lexy: So, there are two different functions within this tool. The first is to show you your impairment level over the course of whatever days you entered in. The other is to predict your optimal caffeine intake in order to maintain peak awareness levels. So there is a tool in there where you can assign when you want to be awake and it will tell you when and how much caffeine to drink Marie: when you want to be most alert. Lexy: True — when you want to be most alert. And then he goes back to caffeine and he can drink a red bull and actually has an effect for him. Lexy: Wait, so, so you mean to tell me the caffeine works like a drug and that over time if you continue to use it, you may need more of it to get the same effect? Marie: Yes. I have my dad. Big coffee drinker. And one year for lent he gave up coffee. Lexy: Oh that had to be painful. Marie: He went through big withdrawals. Lexy: Oh Gosh. Marie: Headaches and everything. Lexy: Been there, done that. Not Fun. Marie: Yeah. So caffeine is a drug. Lexy: Yeah, exactly. Marie: There is a time and a place for it for sure. Lexy: Exactly. Marie: So there are different ways that people deal with their caffeine consumption. Sometimes you try to maintain it and sometimes you do want to decrease it or maybe you want to eliminate caffeine. This tool could also help you see how to do that with maybe a more regular sleep schedule or with maybe being able to incorporate naps into your schedule. Or what was really interesting as we saw that over time, the more days that you kind of go with sleep deprivation, it shows gradually how your response time degrades. So it could also help you determine like, do I have enough sleep banked where I can kind of skimp on hours for this night and be okay? Or, you know, do I need to get into a more regular pattern? So we encourage all of you to jump onto the tool and test out the algorithms yourself and see what you find. Lexy: Mmhmm. I personally would love to see this be a justification for the adoption of Siesta across the world. Marie: We should all adopt this great Spanish tradition. Lexy: Way to go Spain, you figured it out. Lexy: Having access to these tools and without it being a supervised kind of medically-warranted assessment is a little bit dangerous. Marie: Oh, absolutely not. Lexy: Yes. Lexy: Yeah. Lexy: True. Marie: Yeah. Like it shows that as you were saying over the course of multiple days of not getting sufficient sleep, you will get progressively worse. But then if you get a good long nights rest, your impairment drops considerably. Marie: Good point. And you can have a more regular sleep cycle and be more well rested and be more alert on your own. I need to get through these four years of college. Lexy: Yeah. And certainly has an impact here. And then beyond that it starts to get really problematic. Definitely look at all the research, definitely do your homework. This is not the only thing out there. Marie: They do. Lexy: Agreed. Marie: Very true. Lexy: Thanks so much for joining us on this episode of the Data Science Ethics podcast. I hope you get into to be alert and play around with it for yourself. Let us know what you find. Marie: And the next time you have a caffeinated beverage you can think of us. So cheers to that. Lexy: This has been Lexy Kassan Marie: and Marie Weber. Lexy: Thanks so much. Marie: Bye.
