How to stay safe online for students - 12 online safety tips to teach your students

It would be fair to say that many parents, guardians, teachers, and other adults responsible for the wellbeing of young people, are very concerned about the risks and dangers of digital technology for children and teens. It would also be fair to say they have good reason to be so concerned.聽聽

However, the solutions typically proposed to address these concerns are less reasonable. Interventions like bans or limits on phones or social media for younger people, restricting what devices they can use, or granting parents and guardians total control over their younger people鈥檚 digital activity.聽

The problem is, such interventions are harsh, unlikely to work, likely to breed resentment and conflict, and ultimately not in-keeping with the available evidence regarding the reality of digital technology, and the impact it has on younger people. And older ones too.聽聽聽聽聽

Because whatever you think of them, phones and other devices are an unavoidable part of life now. And a significant chunk of modern life, including much of childhood, now takes place online.聽聽

So, if we can鈥檛 remove digital technology from young people鈥檚 lives, we should do what we can to ensure they use it safely, wisely, and in as healthy a manner as possible.聽

With that in mind, here are some evidence-based tips to pass on to students, to ensure they stay safe and maintain a positive relationship with the digital realm.聽

Ways to keep students safe online聽

Children on mobiles surrounded by icons signifying the online world

If you鈥檙e going to be using screens, vary the screens聽

A young person鈥檚 eyes are growing and changing like every other body part. But if you only ever look at your phone held five inches from your nose, for hours a day, the muscles that allow us to focus at different differences don鈥檛 develop as they should, causing myopia and other issues. 聽

This can be avoided just by regularly switching to screens at different distances, whether it鈥檚 from phone to tv to console.聽聽

It鈥檚 ok to use phones, as long as that鈥檚 not all you do聽

Children and teens are growing rapidly, and their growing bodies are shaped by the activity they do. So, if you spend most of your time sat down, hunched over a phone, your developing body will think that鈥檚 all you need to do, which can lead to physical issues as you enter adulthood. 聽

We call them mobile phones for a reason. Don鈥檛 let them stop you moving.聽

Phones in bed are not a good idea聽

Young people, especially teens, need more sleep than adults, and at different times. And they often don鈥檛 get it, because of school and parental expectations. But while it鈥檚 tempted to keep using your phone when you鈥檙e already in bed, it鈥檚 a bad idea. The blue light, the constant novelty, the never-ending feeds; all these can end up delaying and disrupting sleep even further, causing all manner of issues.聽

It's always better to finish with your phone for the day before you get into bed. Not after.聽

Keep your phone on silent, and leave it out of arms reach from your bed聽

Phones and devices can also disrupt sleep by waking young people up. An alert or noise at a certain moment in the night can throw a whole sleep cycle out of whack, and if you鈥檝e checked your phone to see what it was, your brain has 鈥榳oken up鈥 even more.聽聽

Keeping a phone on silent and keeping it a reasonable distance from your bed can help prevent this. A tired brain is a lazy brain, and if checking your phone in the night involves even slight effort, it鈥檒l usually choose to ignore it and go back to sleep.聽

鈥楩ollowers鈥 are not the same as 鈥榝riends鈥櫬

If you get a lot of followers on a social media account, or a lot of likes on a picture or video you posted, it can feel really good. It makes you feel popular, and respected, and accomplished. And you may well be all those things, but the numbers who like you online don鈥檛 really prove that. Unfortunately, people often forget this, and end up focusing more on their online 鈥榝riends鈥 than real life relationships.聽

This can be very harmful, because real relationships are important for wellbeing, particularly when you鈥檙e younger. But real, healthy relationships take a long time to form, and require constant back-and-forth interactions, mutual respect, and more. You can鈥檛 get this from crowds of anonymous followers, who are just numbers on a screen.聽聽

When it comes to people liking you, focusing on quality is much healthier than focusing on quantity.聽

It鈥檚 a lot easier to look beautiful and successful online聽

Many studies show young people developing body issues or wellbeing problems when confronted with an endless stream of beautiful, successful people living their best lives, which is what platforms like Instagram are always showing us.聽

But one aspect of phones and digital platforms that everyone likes is that they give us complete control over how other people see us. And most people use this to make themselves look as good as possible.聽聽

This means that you鈥檙e seeing a very carefully designed self-image of people online, with all the negatives and unsightly elements airbrushed or edited away, leaving nothing but glamour.聽

It can be upsetting to see all this and think you鈥檙e a hideous failure. But you鈥檙e not. You鈥檙e just seeing the unflattering aspects of your own life, but only the heavily-polished good parts of everyone else鈥檚.聽

Understanding this can help you realise your own situation is not so bad after all, which can help you feel better.聽

Join the discussion, rather than just sit on the virtual side lines.聽

One of the positives of phones and social media is that they connect us with more people than ever before, and connections and interactions are vital for human wellbeing. But that connection doesn鈥檛 really help if it鈥檚 never used.聽聽

Studies suggest that social media platforms can be worse for mental health for young people who never engage in discussions or posts but just observe the whole time. 聽

It's much better for your mental health if you鈥檙e part of a conversation, contributing your own thoughts and creations, rather than digitally eavesdropping on other people having a good time. That just makes you feel worse.聽

Information you like is not the same as information that is true.聽

There鈥檚 a great deal of information available in the online world. But a lot of it is wrong, or deliberately misleading. But it all looks the same? How is anyone meant to tell what鈥檚 what. 聽This is a thorny issue with no easy answers, but question to ask when confronted with information online is this: do I want it to be true?聽

Because if you do鈥 it probably isn鈥檛. Not all the time, of course, but it鈥檚 relatively rare for some new discovery or insight to conform exactly to someone鈥檚 pre-existing beliefs and opinions. The world just doesn鈥檛 work like that. But telling people what they want to hear is a great way to make them support you, maybe even buy things from you. So, any information that tells you exactly what you want to hear should be treated as suspicious and checked with other sources. 聽

Privacy is important聽

While a lot of what happens online can seem very 鈥榯here and gone鈥, the truth is that most of what鈥檚 shared lingers around in some form, for a very long time.聽聽Also, when everyone is hidden behind a profile pic, it鈥檚 harder to know exactly who you鈥檙e talking to. 聽

For these and other reasons, young people should always take a second to think before digitally sharing something private or intimate. Especially if it鈥檚 publicly. Something you shared because you felt it was a good laugh could end up resurfacing 10 years later, in ways that are embarrassing and uncomfortable.聽

Other people don鈥檛 want to be involved with your online life聽

You may want to film some funny video or take a cool selfie in an interesting place for your online output. But if your efforts to do so affect and disrupt other鈥檚 people鈥檚 day, they鈥檙e going to get angry at you, and you technically have no reasonable comeback. Because while you may care about giving your followers and subscribers something to enjoy, your online life and world doesn鈥檛 mean anything to other people.聽 聽

If you want to create content for your channels, that鈥檚 your decision. But nobody else is obliged to sacrifice their peace or plans to let you do so. Forgetting this can lead to even more conflicts.聽聽聽

Bad influences聽

Everyone has their favourite influencer, or YouTube star, or whatever. Charismatic and successful people can be very compelling and easy to look up to. But they鈥檙e still just one person, and if you鈥檝e ever met a person, you鈥檒l know they鈥檙e often wrong about all manner of things. Because it鈥檚 impossible for any one person to know everything.聽

This can become a problem when influencers and high-profile types start spreading ideas and claims that are well outside their own expertise and experience. There鈥檚 a lot of good that the online world provides, but one downside is that there鈥檚 no quality control. Anyone can say anything they like, no matter how wrong or bizarre, and if they have enough followers, people will believe them. 聽For this reason, you should never rely on one single person, or handful of people, for your information. Particularly about important matters. 聽

Stick to who you know聽

In the old days, parents would often tell their children 鈥淣ever speak to strangers鈥. And while digital devices make speaking to strangers easier than ever, this is still good advice for young people.聽

Because while most platforms and online spaces will be fine, it鈥檚 still very easy for a complete stranger to knock up a normal looking profile and start messaging others. And these strangers may have shifty motives or dodgy intentions.聽聽

Because it鈥檚 harder to tell who鈥檚 who online, it鈥檚 best to stick to communicating with people you know in the real world, like your friends and family. This means you can avoid suspicious interactions with unknown types altogether.聽聽
