Are Micro-sleeps Ruining Your Productivity?

Are Micro-sleeps Ruining Your Productivity?

The morning after a night of poor sleep can be rough, as I’m sure you know from firsthand research. For years we’ve known that sleep affects us both physically and mentally—lack of sleep erodes our mental abilities in particular. Just one night of sub-optimal sleep at less than 5 hours might hurt us more the next day than almost two days of no sleep at all.[1]

Despite this, chances are that you spent your morning commute bleary-eyed and desperately clutching a cup of your preferred caffeine fix whilst maintaining a silent litany of “I promise to go to bed earlier tonight!”.

The fact of it is, you may just have to hack your sleep in order to hack your productivity. Actually, you just need to sleep (no hacking necessary) to be more productive. Research tells us that the insufficient sleep you’re currently getting increases the frequency of micro-sleeps[2] and it might just be these micro-sleeps that are ruining your efforts to be your best self.

What is a micro-sleep?

Sitting at your desk at work after getting 4 hours of sleep, you might think you’ve got your workload under control, but you feel your attention slip occasionally. You suddenly and involuntarily lose your focus and it’s a struggle to zone back into full awareness. After a few seconds you manage to get yourself together, but it’s not the last time that this will happen to you today.

Science describes micro-sleep as very short periods of sleep[2], but you may be more familiar with them as unintended lapses in attention[2]. Although short, they are an interruption to your flow and, in a sleep-deprived state, these interruptions might take you longer to recover from.

So why do they occur?

Sleep is a biological necessity, so while we’re awake, our need for sleep builds throughout the day until we fall into bed in the evening. It’s normal to experience crossovers between wakefulness and sleep to a certain extent, but a lack of sleep will expand our sleep debt. A heavy debt will increase the frequency of these crossovers and subsequently, you might find yourself lapsing into micro-sleeps more often[2-3], meaning that you will struggle to concentrate more often and may feel sleepy or tired[4].

If you already struggle with these feelings at work, it’s time to accept that they’re a call for help and not to be ignored until you eventually retire.

Your brain on insufficient sleep

Research thus far has shown that your mood suffers the greatest hit from a lack of sleep[1]. The brain becomes more reactive[5] and emotions can go haywire, causing unstable moods.

One interesting study also showed that we’re more likely to react to negative stimuli[2] when suffering from a lack of zzz’s. Being a bit of a ticking bomb can’t be good in a social setting, especially if you’ve been holding a grudge against your coworker or have suppressed feelings towards your boss.

Insufficient sleep can also affect our mental and creative skills, with lateral and flexible thinking particularly impaired. Furthermore, it has been shown that it takes us longer to complete a task when operating on a lack of sleep[2], especially as our motivation and engagement[2] suffer as well. (Can this explain the cyber loafing problem some have?) In any case, it’s safe to assume that even the tasks that come automatically to us, might be harder to get crossed off our to-do lists.

Even if you push through and complete a task, it’s likely there will be errors[2] you’ll have to spend further time correcting as chronic sleep deprivation decreases speed and accuracy[3]. Let’s face it—the time spent correcting errors could have been better put to use, like on a full night’s sleep.

But I do get enough sleep!

Are you sure? In another effort to prove us all wrong, research reveals that we tend to think we’ve gotten enough sleep even when we haven’t[3]. Furthermore, we tend to greatly overestimate our cognitive performance when chronically sleep-deprived; although we think we’re doing well, our performance might have actually plummeted.[3]

It looks like sleep might be the best first step towards optimising your productivity. Even without delving into polyphasic sleep and other experiments, just getting a good night’s sleep might help you refresh enough for you to make the most of your day at work.

If there’s one thing you’ll take away from this article, it should be this quote by Jim Butcher:

Sleep is God. Go worship.

Make that the litany inside your head.

If it’s the middle of your workday, you’re struggling with being productive at this very moment and thinking that this article is absolutely useless, I’ve got a morsel for you too. Here are:

3 scientifically-backed truths to quickly boost your productivity:

1. Get some exercise: Research has shown that exercise increases productivity so that we are both able to do more and do it better.[6] The good news is that you don’t have to go off to slave away at the gym—even a walk around the office or a run up the stairs might help. If you can find the time, go do it now.

2. Be happy: Think positively and feed positive emotions—happiness can increase an employee’s productivity so that he does more while maintaining a level of quality to his work[7]. In this context, happiness entails any positive emotion experienced often.[7]

3. Try being mindful:Research has shown that even the short-term practice of mindfulness can improve our ability to remain focused as well as our mood and cognitive processes[8].

13 Bad Habits You Need to Quit Right Away

13 Bad Habits You Need to Quit Right Away

Creating your productivity ritual — a routine that helps you to maintain a peak level of energy can get you the best out of your days.

Part of creating your productivity routine involves removing activities that drain you (what I call “kryptonites”), and that includes your bad habits.

Like it or not, bad habits are bad for you — mentally, physically, emotionally and even socially in some cases. While some bad habits are harder to quit than others, it doesn’t change the fact that you need to get rid of them. Here are 13 bad habits to quit right away:

1. Stress Eating

I used to be a serious stress eater. I would eat whenever I felt unhappy, stressed, disappointed, anxious, or even… happy! My eating had nothing to do with being hungry, and everything to do with using food to fill my emotional voids.

While eating would comfort me, this feeling was momentary and would disappear right after I was done eating. Instead, what I had left would be the same emotional void that triggered me to eat in the first place (be it unhappiness or stress), a 2,000 excess calorie intake over what I should have eaten for the day, and anger at myself for having stress ate.

I’ve since overcome stress eating. I have healthy eating habits and a healthy relationship with food today where I no longer use food as a tool to fill my emotions.

If you are a stress eater, don’t fret — here’s how to manage your stress better:

2. Nail Biting

Not only is nail biting unhygienic, it is also socially repelling, leads to dental problems like malocclusion of the anterior teeth,[1] potentially cause stomach problems,[2] and lead to severely deformed fingernails in the long run.

People who bite their nails tend to have shorter nails than the average person; their nail plates also experience scarring and may eventually become absent.[3]

Understand what triggers your nail biting behavior and replace it with another neutral to positive habit. Make habits to break habits.

For example, if you bite your nails when you are stressed, go for a walk or listen to music instead the next time you feel stressed.

3. Hanging out with Naysayers

We all know these people — people who play devil’s advocate to every idea you have and every goal you want to pursue. We are already our greatest self-critics, so it doesn’t help when there’s someone beside us, ever ready to pounce on what we say and tear it down.

Hang out less with these naysayers and spend more time with supportive people who share constructive feedback instead. You will be much happier this way.

Learn how to get rid of naysayers with these 10 Ways to Ignore the Naysayers and Achieve Your Dreams.

4. Being with People Who Don’t Appreciate You

Haven’t all of us been in this situation before? Trying to please people who don’t appreciate us? Bending over backwards to be there for people when they are never there for us?

While we give without expectations of return, we need to draw a line with people who don’t value us because these people damage our souls.

Stop spending time with people who don’t appreciate you, and spend more time with people who do instead.

5. Smoking

Smoking is one of the leading causes of preventable death globally.[4]

In just the United States alone, about 500,000 deaths are attributed to smoking-related diseases annually. A recent study estimated that as much as one-third of China’s male population will have significantly shortened life-spans due to smoking! Gender-wise, male and female smokers lose an average of 13.2 and 14.5 years of life respectively — that’s over a decade of life right there.[5]

Not only that, smoking causes pre-mature skin aging (i.e. wrinkles), yellowing of teeth, bad breath, and worse of all — jeopardy of the health of people around you, including your loved ones. Studies have shown that non-smokers exposed to second-hand smoke are at risk to many of the health problems associated with direct smoking.[6]

    6. Excessive Drinking

    All of us know that drinking too much alcohol is bad for us, but do you know how bad it really is?

    Advertising

    According to the National Institute on Alcohol Abuse and Alcoholism, drinking too much — be it on a single occasion or over time — can seriously damage your health:[7]

    • Brain problems: Alcohol interferes with the brain’s communication pathways, making it harder to think clearly and move with coordination.
    • Heart diseases: Cardiomyopathy – Stretching and drooping of heart muscle, Arrhythmias – Irregular heart beat, stroke, high blood pressure
    • Liver diseases: Steatosis or fatty liver, alcoholic hepatitis, fibrosis, cirrhosis
    • Pancreas problems: Pancreatitis, a dangerous inflammation and swelling of the blood vessels in the pancreas that prevents proper digestion.
    • Different types of cancer: Mouth, esophagus, throat, liver, breast

    If you drink a lot, perhaps cutting it out right away will be tough. Cut down the number of glasses you drink each time, followed by the number of times you drink a week.

    If need be, seek help from an AA group — you aren’t alone in this. Change starts from today.

    7. Eating Junk Food (Including Diet Soda)

    Junk food — they are everywhere in our society today. From McDonald’s, to KFC, to Burger King, to 24-hour takeouts, junk food such as fries, highly processed burgers and sodas has become a staple in our society today.

    If you think, “Hey, but junk food is tasty!”, think again:

    A study by Paul Johnson and Paul Kenny suggests that junk food consumption alters brain activity in a way similar to addictive drugs like cocaine and heroin.[8]

    “After many weeks with unlimited access to junk food, the pleasure centers of rat brains became desensitized, requiring more food for pleasure.”

    And you wonder why you seem to crave fast food when you just had some the day before?

    While it may not be possible to remove junk food completely from our diet right away, we can reduce our junk food consumption starting today. Instead of soda, opt for a fruit juice (fresh juice, not the carbonated kind) or mineral water. Instead of fries, switch to mashed potato, a salad, or rice (many food outlets allow for this today). Instead of a fried meat patty, go for a grilled one.

    Where possible, opt for healthy food joints like salad bars and delis as opposed to fast food outlets. Every little step goes a long way.

    8. Eating Too Much Red Meat

    There has been conclusive evidence that consumption of red meat increases the risk of colorectal cancer; and suggestive evidence that it increases the risk of oesophageal cancer, lung cancer, pancreatic cancer, and endometrial cancer.

    Advertising

    In addition, some studies have linked consumption of large quantities of red meat with breast cancer, stomach cancer, lymphoma, bladder cancer, lung cancer and prostate cancer![9]

    Personally, I’m a vegetarian so I don’t consume red meat, but for those of you who consume red meat, do watch out and limit your intake — better still, cut it out of your diet. World Cancer Research Fund recommends limiting intake of red meat to less than 300g (11 oz) cooked weight per week, “very little, if any of which to be processed.”

    9. Watching Too Much TV

    I stopped watching TV since eight years ago and I have never regretted it. Every once in a while I will switch on the telly to see what is on, and then I will switch it off because it’s just the same boring shtick over and over again.

    Watching TV, particularly well-written dramas, can be a good way to unwind. However, remember that TV isn’t your life.

    Spending three hours every night watching TV will not change your life for the better. Rather, using that time to reflect on your life, take stock, and take action on your goals will.

    It’s not easy to remove TV from your daily routine right away, but follow these 6 Steps To Remove TV From Your Life.

    10. Being Late

    Not only is being late being rude to others, it also means that you’re always rushing from one place to another, playing catch up in your agenda, and having to apologize to every person you meet.

    Stop being late and not being punctual, but practice being early instead. Target to arrive 15 minutes earlier before any appointment and bring along something to do in those 15 minutes (or longer if the other person turns out to be late). Then you can stop playing catch up and stay ahead in life.

    11. Being in Bad Relationships

    Are you always dating the wrong guys/girls? Do you end up with jerks all the time? Well, you may not be able to stop yourself from meeting bad partners but you can certainly stop yourself from furthering contact with them, spending time with them, or even… entering into a relationship with them.

    I used to invest myself in this guy who was nothing but toxic for me. After a good five months of experiencing nothing but getting burned over and over again, I realized that he was a total waste of my time and I deserved better. I decided to cut him off, and it was soon after that I met my soulmate.

    12. Leaving Things to the Last Minute

    Burning the midnight oil isn’t fun — it’s exhausting.

    Those of you who got through college by burning the midnight oil would have learned this the hard way. Not only is it damaging for your body, it is also mentally draining as you’re constantly in a hyper-tense mode, feeling anxious about whether you can finish your work on time.

    Start today on a new note. Rather than react to your deadlines, be proactive about them by planning ahead, identifying what needs to be done for the week, and getting things done in advance.

    By staying ahead of your tasks, you can also use your extra time to plan ahead in your life and get more things done.

    13. Focusing on the Negatives

    In every situation, there are two ways you can react: zoom down to the problem areas and crib about how things aren’t the way you want, or celebrate the areas that are going well and work on making everything better.

    Many of us see the importance of doing the latter but in practice, we do the former. Why though? Criticizing and focusing on the negatives is easy but it doesn’t empower nor inspire us to be better.

    Make a change — for every negative encounter you run into, I challenge you to identify three things that are good about it. Practice doing this for one week, and by the end of the week you’ll find that your first instinct is to think positive, not negative.

    The Bottom Line

    So here you find the 13 most common bad habits and their consequences on your mind and body. The good news’ you can quit them all.
