The Impact of Screens on Sleep

Obtaining a good night’s sleep is important for our mood, concentration and psychological well-being. The use of technology at night-time can interfere with both the amount that we sleep and the quality of our sleep. Sleep as you may know, is critical for our mental health.

Impact of bright screens on sleep.

Viewing bright screens (as in from a phone, computer or tablet) at night can significantly impact the time we start to feel sleepy and eventually fall asleep. This is because viewing screens increases alertness and inhibits the secretion of melatonin. Research tells us that viewing screens at night effects sleep, circadian patterns (sleep/wake cycle) and unsurprisingly, next morning alertness.

Screens have a particular type of light that makes them bright and this light mimics the effects of sunlight on the brain. In other words, when we view a bright screen our brain thinks it’s the morning sun and wakes itself up by inhibiting melatonin. Some studies have found that viewing screens up to 5 hours before bed can impact our sleep quality where screens are viewed for 1.5 hours or more.

Technology use increases our mental alertness because we may also become absorbed in what we are doing and delay our bedtime. A meta-analysis of studies with teenagers, found that using technology at night was related to later bedtimes because of the increase in alertness and failure to recognise sleep signals due to being engrossed in technology.

Not all forms of technology use are equally stimulating. Generally speaking, active forms of technology use (playing video games and texting) are more stimulating than passive ones (reading an e-book). Therefore, it’s worth engaging in more passive forms of screen use (or none at all) prior to going to bed.

What to do about screen use.

The first thing is to have ‘no screen time’ for at least on hour before bed. As well as this, a consistent bedtime routine helps to prepare the body and mind for sleep and may be beneficial.

If you can’t bear to be without screens there are few screen light-reducing products that reduce the intensity of the concentrated blue light emitted by bright visual displays. The ones I recommend based on user feedback are:

  • night shift, which is a setting on iPhone/iPads; and
  • F.lux which is both an app for android phones and program for desktops. F.lux is free.

You can also buy orange tinted glasses to further reduce out the concentrated blue light from bright visual displays. These glasses work by blocking out the concentrated blue light.

Avoiding night time temptation to view screens.

The best way to avoid the temptation to respond to texts or looking something up on your phone is to have all devices charging in a separate room. Studies have also shown that young people who have screens in their bedroom get up to an hour’s less sleep per night.

Melbourne, Adelaide … Will you join us? 

The @resilientkidsconference is coming to Melbourne (15 July) and Adelaide (2 September), and we’d love you to join us.

We’ve had a phenomenal response to this conference. Parents and carers are telling us that they’re walking away feeling even more confident, with strategies and information they can use straight away. That’s what this conference is all about. 

We know taking care of the young people in our lives is up there with the most important thing we can do. Why shouldn’t there be a conference for parents and carers?!

I’ll be joining with @maggiedentauthor, @michellemitchell.author, and @drjustincoulson. We’ve got you covered! And we’re there for the day, with you. 

For tickets or more info, search ‘Resilient Kids Conference’ on Google, or go to this link https://www.resilientkidsconference.com.au/conference/.
We have to change the way we talk about anxiety. If we talk about it as a disorder, this is how it feels.

Yes anxiety can be so crushing, and yes it can intrude into every part of their everyday. But the more we talk about anxiety as a disorder, the more we drive ‘anxiety about the anxiety’. Even for big anxiety, there is nothing to be served in talking about it as a disorder. 

There is another option. We change the face of it - from an intruder or deficiency, to an ally. We change the story - from ‘There’s something wrong with me’ to, ‘I’m doing something hard.’ I’ve seen the difference this makes, over and over.

This doesn’t mean we ignore anxiety. Actually we do the opposite. We acknowledge it. We explain it for what it is: the healthy, powerful response of a magnificent brain that is doing exactly what brains are meant to do - protect us. This is why I wrote Hey Warrior.

What we focus on is what becomes powerful. If we focus on the anxiety, it will big itself up to unbearable.

What we need to do is focus on both sides - the anxiety and the brave. Anxiety, courage, strength - they all exist together. 

Anxiety isn’t the absence of brave, it’s the calling of brave. It’s there because you’re about to do something hard, brave, meaningful - not because there’s something wrong with you.

First, acknowledge the anxiety. Without this validation, anxiety will continue to do its job and prepare the body for fight or flight, and drive big feelings to recruit the safety of another human.

Then, we speak to the brave. We know it’s there, so we usher it into the light:

‘Yes I know this is big. It’s hard [being away from the people you love] isn’t it. And I know you can do this. We can do hard things can’t we.

You are one of the bravest, strongest people I know. Being brave feels scary and hard sometimes doesn’t it. It feels like brave isn’t there, but it’s always there. Always. And you know what else I know? It gets easier every time. I’ve know this because I’ve seen you do hard things, and because I’ve felt like this too, so many times. I know that you and me, even when we feel anxious, we can do brave. It’s always in you. I know that for certain.’♥️
Our job as parents isn’t to remove their distress around boundaries, but to give them the experiences to recognise they can handle boundaries - holding theirs and respecting the boundaries others. 

Every time we hold a boundary, we are giving our kids the precious opportunity to learn how to hold their own.

If we don’t have boundaries, the risk is that our children won’t either. We can talk all we want about the importance of boundaries, but if we don’t show them, how can they learn? Inadvertently, by avoiding boundary collisions with them, we are teaching them to avoid conflict at all costs. 

In practice, this might look like learning to put themselves, their needs, and their feelings away for the sake of peace. Alternatively, they might feel the need to control other people and situations even more. If they haven’t had the experience of surviving a collision of needs or wants, and feeling loved and accepted through that, conflicting needs will feel scary and intolerable.

Similarly, if we hold our boundaries too harshly and meet their boundary collisions with shame, yelling, punishment or harsh consequences, this is how we’re teaching them to respond to disagreement, or diverse needs and wants. We’re teaching them to yell, fight dirty, punish, or overbear those who disagree. 

They might also go the other way. If boundaries are associated with feeling shamed, lonely, ‘bad’, they might instead surrender boundaries and again put themselves away to preserve the relationship and the comfort of others. This is because any boundary they hold might feel too much, too cruel, or too rejecting, so ‘no boundary’ will be the safest option. 

If we want our children to hold their boundaries respectfully and kindly, and with strength, we will have to go first.

It’s easy to think there are only two options. Either:
- We focus on the boundary at the expense of the relationship and staying connected to them.
- We focus on the connection at the expense of the boundary. 

But there is a third option, and that is to do both - at the same time. We hold the boundary, while at the same time we attend to the relationship. We hold the boundary, but with warmth.♥️
Sometimes finding the right words is hard. When their words are angry and out of control, it’s because that’s how they feel. 

Eventually we want to grow them into people who can feel all their feelings and lasso them into words that won’t break people, but this will take time.

In the meantime, they’ll need us to model the words and hold the boundaries firmly and lovingly. This might sound like:

‘It’s okay to be angry, and it’s okay not to like my decision. It’s not okay to speak to me like that. I know you know that. My answer is still no.’

Then, when they’re back to calm, have the conversation: 

‘I wonder if sometimes when you say you don’t like me, what you really mean is that you don’t like what I’ve done. It’s okay to be angry at me. It’s okay to tell me you’re angry at me. It’s not okay to be disrespectful.

What’s important is that you don’t let what someone has done turn you into someone you’re not. You’re such a great kid. You’re fun, funny, kind, honest, respectful. I know you know that yelling mean things isn’t okay. What might be a better way to tell me that you’re angry, or annoyed at what I’ve said?’♥️
We humans feel safest when we know where the edges are. Without boundaries it can feel like walking along the edge of a mountain without guard rails.

Boundaries must come with two things - love and leadership. They shouldn’t feel hollow, and they don’t need to feel like brick walls. They can be held firmly and lovingly.

Boundaries without the ‘loving’ will feel shaming, lonely, harsh. Understandably children will want to shield from this. This ‘shielding’ looks like keeping their messes from us. We drive them into the secretive and the forbidden because we squander precious opportunities to guide them.

Harsh consequences don’t teach them to avoid bad decisions. They teach them to avoid us.

They need both: boundaries, held lovingly.

First, decide on the boundary. Boundaries aren’t about what we want them to do. We can’t control that. Boundaries are about what we’ll do when the rules are broken.

If the rule is, ‘Be respectful’ - they’re in charge of what they do, you’re in charge of the boundary.

Attend to boundaries AND relationship. ‘It’s okay to be angry at me. (Rel’ship) No, I won’t let you speak to me like that. (Boundary). I want to hear what you have to say. (R). I won’t listen while you’re speaking like that. (B). I’m  going to wait until you can speak in a way I can hear. I’m right here. (R).

If the ‘leadership’ part is hard, think about what boundaries meant for you when you were young. If they felt cruel or shaming, it’s understandable that that’s how boundaries feel for you now. You don’t have to do boundaries the way your parents did. Don’t get rid of the boundary. Add in a loving way to hold them.

If the ‘loving’ part is hard, and if their behaviour enrages you, what was it like for you when you had big feelings as a child? If nobody supported you through feelings or behaviour, it’s understandable that their big feelings and behaviour will drive anger in you.

Anger exists as a shield for other more vulnerable feelings. What might your anger be shielding - loneliness? Anxiety? Feeling unseen? See through the behaviour to the need or feeling behind it: This is a great kid who is struggling right now. Reject the behaviour, support the child.♥️
