You’re Not You When You’re Tired. How a Lack of Sleep Can Lead to Anxiety & Arguments

You're Not You When You're Tired: How a Lack of Sleep Can Lead to Anxiety & Arguments

Sleep is one of those things that has an absence as powerful as its presence. A lack of sleep comes with its own face – eyelids that hang, eyes that are redder and more swollen, darker circles, paler skin, wrinkles or fine lines, and a wilting mouth. It is a face that is often identified by others as being sad, communicating, perhaps, that they should go gently. There are also major changes that we can’t see. The brain is shaped by every experience, and a scarcity of pillow time is a heavyweight when it comes to having an influence.

Being able to tell what is important is vital to effectively reading people and situations, but a lack of sleep causes us to lose our neutrality. New research has found that one night of limited sleep is enough to wreak havoc with the brain’s ability to tell what is important, leading it to see everything as significant. It also is enough to weaken our ability to regulate our emotions, and it causes problems for cognitive processing. We will always struggle to learn, remember, attend, judge, solve problems or make decision when we’re wrestling with a lack of sleep.

The research. What they did.

For the study, researchers kept 18 adults awake all night. Following their sleepless night, researchers mapped the brains of the participants who were asked to identify the direction of travel of small yellow dots that moved over distracting images. The images were chosen because of their different emotional impacts – ‘positively emotional’ (a cat), ‘negatively emotional’ (a mutilated body), or ‘neutral’ (a spoon).

After a good night’s sleep, the participants were quicker and more accurate in identifying the direction of the dots hovering over the neutral images. Brain scans revealed the brain responded differently, depending on whether the images were neutral or emotional.

In contrast, when the participants were sleep deprived, they performed badly for both the neutral and the emotional images. According to brain scans, there was very little difference to the way their brains responded to the emotional and the neutral images.

It could be that sleep deprivation universally impairs judgement, but it is more likely that a lack of sleep causes neutral images to provoke an emotional response.Ben-Simon, Researcher, Tel Aviv University.

 In the second part of the study, researchers tested concentration, and the degree to which emotional things or neutral things caused distraction. After only one night of a lack of sleep, participants were distracted by every image – neutral and emotional. On the other hand, the participants who had plenty of sleep were only distracted by the emotional images.

 Interestingly, brain scans revealed that the part of the brain involved was the amygdala. The amygdala is key to the detection of threat and the activation of the fight or flight response. It’s a big player in anxiety and in any situation that involves confrontation (fight) or avoidance (flight).

What it means.

Without sleep, we’ll struggle to tell the difference between the things that could hurt us and the things that won’t. Our brains give as much weight to something neutral as it does to something more emotional. Understandably, this can lead to a bucketload of trouble.

We may experience similar emotional provocations from all incoming events, even neutral ones, and lose our ability to sort out more or less important information. This can lead to biased cognitive processing and poor judgement as well as anxiety.’ -Professor Talma Hendler, Tel Aviv Universisty’s Sagol School of Neuroscience.

Our brains are constantly scanning the environment for threats. We’re all wired to do this and it’s important to keeping ourselves safe. It does this beautifully, but sometimes it can do it too much. Not only does a lack of sleep tend us towards being cranky or irritable, it also puts our brain on high alert.

Being able to read the environment and respond appropriately is critical to having healthy relationships and to living well. The problem with having a brain that’s so quick to interpret things as potential trouble, is the heightened tendency to respond to harmless things as though they could be a problem.

 It’s no surprise then, that when we’re tired, we can be fragile or quick to temper when something is said or done, much to the confusion of the innocent ones in the line of fire. It also makes it clear why it’s so important to catch plenty of peaceful zzz’s the night before something difficult – an exam, an interview, a date. Our brains love sleep, they adore it, and given that we’re completely reliant on our brains to walk us through life as seamlessly as we can, one of the best things we can do for ourselves is to make sure we get plenty of uninterrupted, blissful pillow time.

I hadn’t thought of the inability to screen out emotional responses to neutral occurrences before. “Last straw” & “flying off the handle” “post partum Blues”, so many times and expressions make more sense when seen in that context.
Now, if for various health, economic, or reasons beyond one’s control, that good night’s sleep is not going to occur, what are some useful tools in handling this response?

It makes a lot of sense doesn’t it. I know what you mean – sometimes sleep is easier said than done. If a good night’s sleep is something that isn’t going to come easily, try mindfulness. Even 10-20 minutes a day will make a difference. It been proven to have some amazing capacities to strengthen the brain, including helping to protect the brain against anxiety, stress, depression – and so much more. It really is incredible. Here is some information here https://www.heysigmund.com/category/being-human/mindfulness/ . There are plenty of ways to practice mindfulness but there is a free app from Smiling Minds which is a great way to get started. It has mindful meditations on it for kids to adults http://smilingmind.com.au. Hope this helps towards a happy brain.

Great article. Very interesting study! I notice this on myself a lot. When I’m tired I get very irritable and emotional over small things. It makes sense that sleep plays a big role in our anxiety.

It’s a great study isn’t it. It makes a difference to understand why we do what we do, and this is a study that just makes pieces click into place – it makes a lot of sense!

Great article – but as with every article that recommends 7 – 8 hours’ sleep, I find myself wondering ‘what about mums of young children’? My child is now 3 and sleep pattern remains mixed, but we are guaranteed at least one waking per night (which incidentally I can cope with, it’s 2+ wakings that wreak havoc!).
I’m not a believer in controlled crying methods, so we try to go with the flow, encouraging good sleep but managing wakings with as much compassion as we can muster. Does this condemn me to being a terrible person until we are through this phase? I can’t be the only mum who has experienced prolonged sleep disturbance!

You are definitely not alone there! It’s something that all parents of young children go through, including myself (for about 10 years!) 7-8 hours is an ideal but for a lot of people, including shift workers and people with young children etc, it’s just not possible. If you aren’t able to get 7-8 hours, don’t worry – it won’t make you an awful person! If you aren’t sleeping well, try to do as much as you can to add in the other lifestyle factors. Remember that these are all ideals, and anything you can do will make a difference.

During adolescence, our teens are more likely to pay attention to the positives of a situation over the negatives. This can be a great thing. The courage that comes from this will help them try new things, explore their independence, and learn the things they need to learn to be happy, healthy adults. But it can also land them in bucketloads of trouble. 

Here’s the thing. Our teens don’t want to do the wrong thing and they don’t want to go behind our backs, but they also don’t want to be controlled by us, or have any sense that we might be stifling their way towards independence. The cold truth of it all is that if they want something badly enough, and if they feel as though we are intruding or that we are making arbitrary decisions just because we can, or that we don’t get how important something is to them, they have the will, the smarts and the means to do it with or without or approval. 

So what do we do? Of course we don’t want to say ‘yes’ to everything, so our job becomes one of influence over control. To keep them as safe as we can, rather than saying ‘no’ (which they might ignore anyway) we want to engage their prefrontal cortex (thinking brain) so they can be more considered in their decision making. 

Our teens are very capable of making good decisions, but because the rational, logical, thinking prefrontal cortex won’t be fully online until their 20s (closer to 30 in boys), we need to wake it up and bring it to the decision party whenever we can. 

Do this by first softening the landing:
‘I can see how important this is for you. You really want to be with your friends. I absolutely get that.’
Then, gently bring that thinking brain to the table:
‘It sounds as though there’s so much to love in this for you. I don’t want to get in your way but I need to know you’ve thought about the risks and planned for them. What are some things that could go wrong?’
Then, we really make the prefrontal cortex kick up a gear by engaging its problem solving capacities:
‘What’s the plan if that happens.’
Remember, during adolescence we switch from managers to consultants. Assume a leadership presence, but in a way that is warm, loving, and collaborative.♥️
Big feelings and big behaviour are a call for us to come closer. They won’t always feel like that, but they are. Not ‘closer’ in an intrusive ‘I need you to stop this’ way, but closer in a ‘I’ve got you, I can handle all of you’ kind of way - no judgement, no need for you to be different - I’m just going to make space for this feeling to find its way through. 

Our kids and teens are no different to us. When we have feelings that fill us to overloaded, the last thing we need is someone telling us that it’s not the way to behave, or to calm down, or that we’re unbearable when we’re like this. Nup. What we need, and what they need, is a safe place to find our out breath, to let the energy connected to that feeling move through us and out of us so we can rest. 
.
But how? First, don’t take big feelings personally. They aren’t a reflection on you, your parenting, or your child. Big feelings have wisdom contained in them about what’s needed more, or less, or what feels intolerable right now. Sometimes it might be as basic as a sleep or food. Maybe more power, influence, independence, or connection with you. Maybe there’s too much stress and it’s hitting their ceiling and ricocheting off their edges. Like all wisdom, it doesn’t always find a gentle way through. That’s okay, that will come. Our kids can’t learn to manage big feelings, or respect the wisdom embodied in those big feelings if they don’t have experience with big feelings. 
.
We also need to make sure we are responding to them in the moment, not a fear or an inherited ‘should’ of our own. These are the messages we swallowed whole at some point - ‘happy kids should never get sad or angry’, ‘kids should always behave,’ ‘I should be able to protect my kids from feeling bad,’ ‘big feelings are bad feelings’, ‘bad behaviour means bad kids, which means bad parents.’ All these shoulds are feisty show ponies that assume more ‘rightness’ than they deserve. They are usually historic, and when we really examine them, they’re also irrelevant.
.
Finally, try not to let the symptoms of big feelings disrupt the connection. Then, when calm comes, we will have the influence we need for the conversations that matter.
"Be patient. We don’t know what we want to do or who we want to be. That feels really bad sometimes. Just keep reminding us that it’s okay that we don’t have it all figured out yet, and maybe remind yourself sometimes too."

Would you be more likely to take advice from someone who listened to you first, or someone who insisted they knew best and worked hard to convince you? Our teens are just like us. If we want them to consider our advice and be open to our influence, making sure they feel heard is so important. Being right doesn't count for much at all if we aren't being heard.
⠀⠀
Hear what they think, what they want, why they think they're right, and why it’s important to them. Sometimes we'll want to change our mind, and sometimes we'll want to stand firm. When they feel fully heard, it’s more likely that they’ll be able to trust that our decisions or advice are given fully informed and with all of their needs considered. And we all need that.

"We’re pretty sure that when you say no to something it’s because you don’t understand why it’s so important to us. Of course you’ll need to say 'no' sometimes, and if you do, let us know that you understand the importance of whatever it is we’re asking for. It will make your ‘no’ much easier to accept. We need to know that you get it. Listen to what we have to say and ask questions to understand, not to prove us wrong. We’re not trying to control you or manipulate you. Some things might not seem important to you but if we’re asking, they’re really important to us.❤️"
