You'll see links to F.lux [0] occasionally on HN, but I can't overstate how F.lux has changed my life.
Before F.lux, my laptop would suck me in. I would browse HN, Metafilter, and Twitter even as my eyes stung and my head felt like a bag of sand. Eventually I would go to bed at 3am, confused about how time flew by so quickly.
The next morning was always rough. Some days I would wake up at 8am and arrive at work on time with a headache. Sometimes I would jump up at a quarter to nine, arrive an hour late, and chug two tall cups of coffee before noon. I'm embarrassed to say that I called in sick a few times because I was too exhausted to get out of bed. This was a terrible existence.
With F.lux I feel myself getting sleepy. After a certain hour, my body kills any running mental processes and orders me to sleep. I always get sunlight and exercise, but eliminating blue light in this controlled experiment (with F.lux and a Kindle for late-night reading) has dramatically improved my quality of sleep.
My only problem with F.lux is that I can't find the "Donate" link on their page.
OP here. I've been using F.lux for several years now. I really can't understand why anyone would not use it. It's so easy on the eyes.
If you like F.lux and you're an OSX user, I'd also recommend using it with Toggle Screenshade [http://screenshade.en.softonic.com/mac]. It doesn't change the color composition like F.lux does. It just reduces the brightness of the monitor well below OSX default minimum. It's shocking little light that gets through. Give yourself 2 minutes to adjust in a dark room, and you'll still be able to see the monitor, but with much less light intrusion on your body.
Second, if you're getting hardcore on this. You should also buy a orange plastic screen shade from Low Blue Lights [https://www.lowbluelights.com/products.asp?cid=16] or make one yourself. I have one rubber-banded to my monitor at night. It ~triples the effect of Flux.
Can't overstate this. For some reason Flux got deactivated on my computer. I just found out. The last nights my sleep shift has shifted and shifted. Until 6am bed time. Go figure.
For mornings, esp. in winter, I use a day light lamp [1]. Highly recommended.
As I understand it, F.lux works because your body uses light cues to determine the rate of melatonin production. Essentially: less light (or warmer light) => more melatonin production => sleepiness.
Rather than mess around with your monitors' color balance (which I find extremely annoying), I just skip the first step and pop an over the counter melatonin pill. It works splendidly, doesn't seem to be habit forming (been using it on and off for 5 years; it basically got me through the last 2 years of college), and doesn't seem to have any adverse side effects other than more vivid dreams (or, equivalently, better recollection of dreams).
Oh my god this app is amazing!! How did I not know about it!
It's midnight here, I was feeling bleary-eyed and wide awake, switched on F.lux, and now I feel like I'm being bathed in the warm glow of a nightlight..
1. I love F.lux as well but it is (still) buggy for me, especially on my living room Mac Mini (where it is connected to an HDTV – F.lux never remembers to apply the white-point shift after the display reawakens…).
2. If people would like to see their iPhone/iPad/iPod Touch do the same thing, Apple needs to allow such functionality. Request F.lux support – native or by exposing an API – on iOS by duping #10158436 on http://bugreport.apple.com. (Please!)
Thanks for mentioning F.lux. I recall reading about it a while back but never tried it. I'm planning to install it tomorrow.
I did a quick search for an iPad equivalent, but nothing promising turned up. I'll keep looking. Much of my evening and night reading is on the iPad and I've wondered if the 'glow' has been disrupting my sleep.
If anyone has suggestions for non-jailbroken iOS devices, please share. Thanks.
I had heard it mentioned before but just installed it for the first time. It's only been 5 minutes and I've already adjusted pretty well to the color balance shift. I thought that it would end up driving me nuts but I think this'll really help. Thanks for the recommendation!
I have thought about this before, and I can confidently trace it back to two causes in my own life.
1) This was happening even when I was a developer and not just an entrepreneur. It is because when you are working on a problem, you want to reach a "save state" before going away. So you can pick up where you left off in the morning. Sometimes you think the "save state" is just an hour away and it turns out to be 3 hours or more. Basically you have the context in your head NOW and it's annoying to have to serialize it into something and unserialize it later. You want to at least finish a subtask. As a result, the "bedtime" of a developer is indefinite, unlike in 9-5 careers where you can clock out and stop thinking about things.
For entrepreneurs, this is a smaller problem, but for developer-entrepreneurs, it is a combined problem. The entrepreneur might be puzzle-solving at night as well, and doesn't want to have to serialize/unserialize in some arbitrary state. Also their brain gets used to problem solving and can't stop. Kind of like this: http://xkcd.com/356/
2) Now, the second reason is that we are probably young, in our 20s or early 30s. As a result, we came out of a college environment and late night partying is important to younger people. Late night anything, because one again, that is the time that young people have for themselves and they don't want to put a definite curfew on it. You can be more irresponsible earlier in life, drinking and socializing until late. In addition, many young people have to study in college and aren't gonna get fired if they don't show up at 8 AM to work, so once again we have this "I don't want to put this book down until I've finished the chapter" thing.
As you get older and have a family, if you have to wake up early, then your habits will change.
I also have a theory that young people have ALWAYS been more nocturnal than their elders, who become morning people at 70 :)
I can't speak for everyone, but for some it's a case of never being able to get your brain to shut down properly from a work point of view, which can be both the reason for sleep problems and the reason for success.
My current boss summed it up once when he said "the reason I'm always working outside hours [he works most evenings, will often get an email from him at 3am, most days a call sometime between 8pm and midnight - and this isn't some young startup hacker, he's a successful CEO of 10 years] is that I'm afraid of missing any opportunities".
Another way of putting that is Carpe Diem, one of my favourite quotes.
I'm the same, no matter what I'm doing - including trying to get to sleep - thoughts keep cropping up. Should we be talking to Company X. Do we need to hire Person Y. Why haven't we created Product Z.
I've found my poor sleep correlates with how late I'm working on a problem. I try to go to bed around 11pm. If I'm done working by 6pm I'm more likely to sleep ok. 8pm is pushing it. Any later than that the problem won't be out of my head by the time I lay down, and it stays there all night.
First thing is nope I had the problems like his before I had a computer. Had it when I was a kid and right though out high school, right now I'm staying with my parents while I focus on some products, and am waking around 10am again, thats my naturally sleep pattern 2am-10am.
But I'll agree the computer CAN makes it worse ... because even as the guy mentioned controlling light can be critical. On the flip side it can make it easier to sleep by mentally tiring you, if you have a problem you have to test it and see. Both are true for me.
As for what he said about lighting 100% agree with it. I summed it up the other day here talking about how I created a fake sun rise in my room : http://news.ycombinator.com/item?id=2990669 what I didn't mention was I hid every single light source. My room was pitch black, I rewired my body clock by controlling the light.
in 20 years we will look back at our "work" and not see a "life" around it. I burn the midnight oil and watch the sun come up once a week, but turning off the desk lamp at 5pm to engage in life is critical for me to be recharged for the next days' opportunities and challenges.
I've used the goLITE BLU device for just over a year now and have found it to be really effective for giving me more energy. Use cases: full blast soon after waking up to reset my circadian rhythms and then on a lower setting later in the day. (You obviously need to be careful not to use it too late in the day as it will inhibit the synthesis of serotonin into melatonin.) I would describe the energy boost as subtle, but effective and long-lasting.
That said, it's way overpriced. You could make your own device for MUCH less. Basically, any blue leds operating around 470 nm, which are pennies apiece on digi-key, would work. Wire up a whole bunch in parallel, put them behind a diffuser and you're good to go!
Looks like there has been significant research on chronotype (A person's preference for daytime vs. nighttime activities). One study showed "About 1/10 people are actually hard-wired... to be early risers" and "2/10 people are what are known as night owls". So there maybe some proof to your genetics theory. People maybe hardwired to reach peak functionality at different times.
Which would make sense in evolutionary terms. You want someone in your group to be awake at night as a watch. Its also very helpful to have very early morning risers, to prepare stuff for the group.
I've always been a night owl (fortunately, not DSPS) with my most productive hours and highest energy late into the evening. This usually led me to wake up late too, as you'd expect.
In the last few months, however, I've found myself waking up early too - because I am so excited about what I am working on. Sometimes, I'll try to sleep in. All that leads me to do is just lie there, thinking about all the stuff I could be doing instead.
What I perhaps ought to do is take a siesta in the afternoon to balance out this lack of sleep. I haven't done that yet though...
(Web) Entrepreneurs don't sleep because they're proficient with the internet. Not only do you get into a routine of not going to sleep, but your also not really trying to. I know, this was me!
Now I try to unwind, I have to make conscious decision to down tools and watch the TV, set the timer. I have a time when I know I should really have my head down.
On the flip-side, 2-3 years ago - I was up till 6-7am, waking at 12/1pm and repeating all over again. After all, I had the internet (read: unlimited stuff to look at) and nothing to get up for.
I think light sensitivity can also play a role in this. I find direct sunlight uncomfortable, especially in summer and winter (sun reflecting off the snow). As soon as evening begins my brain fires into gear. I think other Asperger's types might struggle w this too, without even realizing it.
A friend recently recommended using sunglasses more, which I'm going to try out. Makes sense
Interestingly enough my Uncle is the same way. He is an entrepreneur although, his business has absolutely nothing to do with the tech industry, so it's not a problem unique to hackers, but to startups. Along with my own experience, my startup is in tech field, of trying to get a startup up and running I would have to say number 4 is probably, at least in my and my uncle's case, the most probable cause of insomnia. The later it gets the less texts I get, the less emails to answer, my friends are all asleep, and I feel like I can finally get some work done.
When I was working a full-time job, I found I could be super productive between 7am and 9am before most other people got in, then I wouldn't really get a huge amount done beyond supervisory and mentoring type work until 8pm or so when I could restart working.
Currently, on my own stuff, I work about 11pm to 3 or 4am which has been super productive but somewhat tiring. The huge benefit is almost complete peace and quiet, which really helps me focus.
I'm in High School and regularly go to bed later than 3 because of the points you raised. F.lux has also made my life much better. I love to wake up early, that's my other problem. I hate to sleep in and waste time.
