A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.
Tell us what you love.Napping is a evolutionarily habit that still works wonders today. I can get by with several hours less sleep per night by adding a 20-minute nap in the afternoon. But I work at home where napping is easily done. The point of this book is to persuade you that the benefits of napping, scientifically derived, are so great you should do everything you can to make napping a habit whatever your schedule. As this concise guide makes clear the benefits to nappers are significant: smarter, more productive, healthier. For those who have tried napping without success, this book offers several different methods to try. It is hard to imagine the siesta returning in full force in the workplace, but it should be resurrected in some fashion. Start here. This is the best practical book on naps yet. — KK
You know nothing about nearly a third of your life. Sure, you think you have some sense of how you sleep, but you really don’t. We’re notoriously inaccurate in estimating how long it takes us to fall asleep, how long we’re awake in the middle of the night, how long we dream and how much deep sleep we get. And the total hours you sleep are only one factor of many in determining the quality of that sleep and the restorative effect it will have on you. Even worse, if you want to improve the quality of your sleep, all you’ve got to go on is general advice, while the one thing we know about sleep is that we’re all different.
What you need is data. That’s what Zeo provides. It’s a clock-radio-sized device that sits on your bedside table, with a comfortable wireless headband that you wear while you sleep. The headband measures electrical signals from your brain and can distinguish between four states: awake, light sleep, REM sleep and deep sleep. The base station records all this, and displays all the data in easy to understand charts, as well as recording it on a SD card that you can plug into a computer to upload to a very good website for tracking and analysis.
(It’s also a great alarm clock, which can wake you at the time when you’re most ready to wake, which may be some minutes before the set time)
I was given a Zeo when it first came out last year, and I’m hooked. I knew I was a poor sleeper who is plagued by too-vivid dreams, but here’s what I found out with Zeo: 1) I get very little deep sleep (often less than 10%), which is the most restorative type. My wife, meanwhile, usually gets more than 25% deep sleep over the same period. 2) When I think I’m tossing and turning all night, I’m usually not. The wake periods are typically short, and I am actually asleep between them. 3) There are simple things I can do to improve my sleep, even if I’m not sleeping any more hours.
To that last point, Zeo is all about running experiments on yourself. Take a couple weeks of baseline data to measure day-of-week cyclicality, and then start changing things. For me, the difference between one glass of wine and two a night is an average of five points of “ZQ” score (I average around 80). Cutting off screens (email, web, even reading on the iPad) a half-hour before bed and turning to a paper book also adds about five points. I’d hoped that exercise would add to my score, but it didn’t. Three milligrams of melatonin before bed has a small but positive impact, which may well just be the placebo effect. 11:30 is better for me than 12:00, but 11:00 is no better than 11:30. And so on.
If you’d like better sleep and want to be smart about how you go about it, Zeo is the perfect tool. And even if you don’t have one, subscribe to the Zeo blog, which is full of smart data- and science-driven advice and discussion about sleep quality and how to improve it. — Chris Anderson
Mind Metrics
One of the self-tracking projects that I always wanted to do was to determine the impact of sleep, diet and exercise regimen on my mental and cognitive abilities. I needed an app to measure my cognitive or mental skills/abilities — rather than training or improving them. I also wanted measurement methods to be as close to scientific as possible. And of course the tests should take as little time as possible (preferably under 5 min), and run off portable devices. I settled on Mind Metrics — it’s an awesome phone app that lets me measure alertness, higher cognitive abilities such as attention and memory, and their combination.
For instance, in the alertness test you are asked to tap the sun as soon as it appears in the same part of the screen randomly every few seconds. You can control the number of trials and timing for both tests. After completing a preset number of trials, you get both average reaction time and average attention/memory score. You can see all your current and previous scores on the screen, and also e-mail them to yourself in comma separated format.
I’ve been using Mind Metrics to measure mental alertness in a couple of experiments, including finding the optimal time to go to bed (my finding was that going to bed between 11 and 11:15 leads to higher alertness next morning and better sleep), and validating orthostatic heart rate test (difference between standing and resting heart rate right after waking up reasonably well predicts mental and physical performance later in the day). I am currently using Mind Metrics to track my cognitive well-being on a daily basis. — Konstantin Augemberg
