We talk a lot about productivity on here for two primary reasons – the first is we have a lot of projects we’re passionate about and if we didn’t have a strong interest in productivity ourselves none of them would ever get done, and the second is everyone always wants to be more productive. It’s one of those areas that everyone uniformly wants but struggles with.
While there are a lot of things you can do to increase your productivity it can be easy to get bogged down in the little things. Apps, complicated organizational or notebook systems, specialized methods like timeboxing, and things of that nature all seem cool and exciting.
The problem is when you worry too much about that sort of thing it’s easy to completely ignore the stuff that doesn’t seem as cool – and that’s the stuff that’s actually going to help the most.
Sleep Is a Key Foundation of Productivity
These things getting left by the wayside when people focus on their productivity are often the most foundational elements of being productive. The one we’re going to look at today – because frankly it’s the most important one – is sleep.
If you want to be productive but don’t get eight hours of sleep a night, then you’re shooting yourself in the foot before the race even starts.
Sleep gets a bad reputation nowadays as something for the lazy, or the unambitious. It’s seen as a weakness. People say things like, “Sleep is for the weak,” or, “I’ll sleep when I’m dead.” They act like it’s something to boast about when they go long periods without sleeping or rely on caffeine and other stimulants just to function every day. People act like the truly productive, the hardest of hard workers, sleep little or pull frequent all-nighters in the name of productivity.
All of that is stupid.
Lack of Sleep Destroys Productivity
In a University study from June of 2000 researchers found in the thirty-nine subjects they tested going without sleep for seventeen to nineteen hours caused them to perform as badly on tests as when they tested at a blood alcohol content of 0.05%, with many being worse when tired than when inebriated. Beyond nineteen hours many participants performed worse than they had at a blood alcohol content of 0.1%.
Now, for reference, in most places in the U.S. the legal limit for driving is 0.08%. Seventeen hours of being awake would be waking up at 6 a.m. and staying up until 11 p.m. – which is not an unlikely scenario for many people. People on that schedule could be nearly as impaired as if they were too drunk to drive.
Compounding the problem is the issue of sleep debt.
If you only get three hours of sleep one night, but make sure you get eight the next night, that doesn’t reset you to where you would’ve been if you had gotten two nights of eight hours of sleep. Sleep deprivation accumulates in what’s usually called sleep debt or a sleep deficit.
Research has shown two weeks of getting less than six hours of sleep per night reduces your cognitive ability as much as going a full twenty-four hours without sleeping. A single week of only getting four hours of sleep a night reduced participant’s performance equivalent to going three full days without sleeping.
If you’re getting under six hours of sleep every night, for example if you have to get up around 6 a.m. for work everyday and regularly stay up until midnight, you are performing at a cognitive level equivalent to being too drunk to legally drive.
Caffeine and stimulants may make you feel like they’re making up for it but, just like like drinking a bunch of espresso when you’re drunk, it doesn’t make you perform better it just gives you more energy with which to perform poorly.
Sleep debt is why it’s a stupid idea to think you can be more productive by working late or pulling all-nighters. Let’s assume two example people, Jane and Jim. Both of them have to get up at 6 a.m. every morning for work. Jim routinely stays up until midnight to get a little extra work done. Let’s assume for the sake of the example that Jim genuinely spends those two extra hours working and not on Netflix or Reddit or something. Jane goes to bed at 10 p.m. every night to get a full eight hours.
At the end of the week Jim has put in fourteen more hours of work than Jane. That sounds pretty good, until you realize he’s been performing at a level equivalent with being drunk. Not just for those extra fourteen hours either, but for all of Jim’s productive hours he’s been performing at a severely reduced level.
That means in Jane’s 112 waking hours she’ll not only have been able to do better work, she’ll also have done more work than Jim in his 126 waking hours. Do you think you could get more work done in an hour sober, or after six beers?
Productivity isn’t about the sheer number of hours put in, it’s about the amount of quality work accomplished.
If you’re worrying about productivity apps and don’t-break-the-chain charts but only getting six hours of sleep every night, your priorities are way out of order.
How to Make Sure You’re Sleeping Enough
Okay, so you get now that getting eight hours of sleep every night is crucial for being productive –
how do you go about doing it?
Like with productivity itself there are all sorts of low impact high excitement things out there to help you sleep more and better, and none of them are worth a damn if you don’t have the boring basic stuff down first.
Keep to a Regular Bedtime – We have no problem with the concept of waking up at the same time everyday, so why do people balk at the concept of going to sleep the same way? I’m not sure if people associate a set bedtime as something for children, but going to sleep at a variable time is a great way to not only accidentally stay up too late and deprive yourself of vital sleep, but also a great way to reduce the quality of the sleep you do get.
Set a specific time every night as the time you go to sleep. Stick to it. Don’t make excuses for why you need to stay up a little longer. Don’t let other people talk you out of it. Do you know what’s not childish? Making a decision to do something and sticking to it even when you don’t feel like it.
Avoid Stimuli Before Sleeping/In Bed – If you know when your set bedtime is,
then you can avoid watching TV, playing video games, browsing the Internet, or doing other overly stimulating things for an hour beforehand. You should also avoid doing all those things in bed. Your bed should not be the place you hang out in the evening watching TV and eating snacks and playing around on your iPad.
Your bed is for sleeping, and having sex. If you’re not doing one of those two things, do it somewhere else – and to be fair one of those things can be done somewhere else too. Don’t sit in bed and watch TV until you feel tired. When you get in bed it should be because you are intending to go to sleep. If you toss and turn and aren’t asleep after fifteen minutes, get up and do something relaxing (not TV or anything with a screen) and try again as soon as you start to feel tired.
Avoid Caffeine After Noon and Alcohol Before Bed – Caffeine can stay in your system for longer than you think. Keep all your caffeinated drinks to before noon to be certain the stimulants aren’t keeping you from getting to sleep or reducing the quality of the sleep you’re getting.
Alcohol is no different. Avoid drinking too much close to bedtime since alcohol before bed severely reduces the quality of the sleep you get. It’s fine every now and again, but don’t make it a habit or you’ll ruin your sleep.
These few things might not seem like much, but that’s kind of the point.
They don’t seem cool or flashy but, unlike that fancy app you bought with the expensive peripheral wearable, they’ll actually get you eight hours of quality sleep every night.
Get your sleep in order, and then you can worry about filling in the little details later. Your productivity will increase without you feeling like you’ve even done anything.
