- Your room must be cold. If you stand around in the room you should feel kind of chilly
- Your room should be quiet. If you have loud A/C which turns on and off that's a problem c.f. step 1 -- think hard about how to meet both requirements given your personal situation/constraints
- Your room must be dark. Not necessarily pitch black but dark. No blinking LEDs.
- A couple hours before bed, remind your brain that it is soon time to sleep
- Your phone must not be in the room with you. Your phone sleeps in the kitchen. I cannot emphasize this enough. It's OK you are going to have a nice book to read instead
- You need a real physical book. Books are cheap and make you more sexy and smarter. No Kindle
- There's nothing special about that headtorch -- there are hundreds of head torches you can buy with a red ~630nm LED. it's the standard red color LED. It would be interesting to swap it out for the 670nm wavelength described in the article though!
- Actually that model is pretty heavy and just happens to be the one I bought for camping -- you could do a lot better/smaller/lighter e.g. Nitecore NU25, Black Diamond Spot 350
- You will feel like a clown when you put the headtorch on. That's okay -- you read books and sleep well, making you very attractive in the daytime. It's OK to look like a clown at nighttime
- You are going to sleep on your back. You can do this, I believe in you. You are going to sleep positioned like Tutankhamun and for nearly as long
- You need a reasonably firm pillow and you need to set it up right. It needs to support your neck and stop you rolling on your side. None of this foam bullshit it needs to have feathers in it. You are a human being not a cellphone. You don't sleep on plastic
- OK let's get this bread. You lie down you turn off all the lights and you turn on your cool little headtorch. You get your head very well positioned on the pillow. You are about to sleep like a boss, you're going to sleep like Genghis Khan. You better get those covers tight because it's fucking cold in your room. Then you start reading. Hell yeah this book is so good. It feels so natural and rewarding and you remember that people used to write in ways that are outside our grasp today, no LLM or modern author can touch it. Within a couple of pages your eyes are shut. You find yourself holding the book with your eyes closed, barely awake. At that moment boom you put down the book, ideally switch off the headtorch, and disappear
