Journalists are no longer the gatekeepers. The reality is that many young people are now bypassing the websites and apps of traditional news outlets and seeking information on social media platforms, including TikTok. It’s the ‘fastest growing social network’, according to the Reuters Institute Digital News Report, and new research has found that 20% of 18-24 year olds use the app solely to find their news. While a massive 44% of that age group use the short-form video hosting service for any and every other purpose. The younger generation have “little interest in many conventional news offers oriented towards older generations’ habits, interests, values, and instead embrace the more personality-based, participatory, and personalised options offered by social media”, said Reuters Institute director Rasmus Nielsen. Under 18s are big users too, so for parents whose teens get their news via TikTok, what do you need to understand about the social network and the evolution of digital media literacy? What is TikTok? Every so often a new app emerges and redefines the way we use social media. It’s what TikTok went and did in 2016. Starting as a small niche social media network – founded by Chinese tech giant Zhang Yiming – that attracted lip-synching teens as a short-form video hosting site, it almost knocked Facebook off its perch, and blew up during the coronavirus pandemic to a mega global platform. Do news organisations share news on it? Yes, they do. In many ways, traditional news organisations were forced to join TikTok to avoid being left behind, reach new and younger audiences and ensure they are continuing to find creative ways to pivot in a constantly evolving digital space. “Given the popularity and high engagement level, it’s not surprising that TikTok has become an important news platform for younger audiences, and it makes sense that news organisations are using it,” said Mark Brill, a senior lecturer in Future Media at Birmingham City University. “This, however, is a continuation of an existing trend. For well over a decade social media such as Facebook has been the primary news source for under 25s.” Anna Lee, founder at the Fr. App, added: “We can see that Gen Z individuals are turning to TikTok for any and all searches. While the funniest sound bites and newest dance trends will always have a home on TikTok, you can also equally expect to find videos explaining an arbitrary housing act.” How is it shared? There are various types of videos that can be shared on TikTok. Alongside the short bite-sized videos sharing the latest news, you can share trending sounds, things creators have posted, or videos with friends, family, and your larger community within TikTok or through other social media platforms. Videos can also be shared directly to other users, as long as the user has allowed for it. How do algorithms work? The TikTok algorithm is a recommendation system that determines which videos will appear on your (unique and highly personalised) For You page, which is also known as the homepage. Brill, who has 25 years of experience applying emerging technologies to engage audiences, said: “Much of the success of TikTok is the way that their algorithm decides which videos to show their users. TikTok’s system is based entirely on their interests and previous viewing. “This ‘more of what you like’ approach means that users spend more time each month in TikTok than any other platform. In the UK it adds up to over 27 hours per user per month and 23 hours globally. It shows how the platform’s algorithm can be highly addictive.” Is it OK that TikTok is how young people learn about what’s happening in the world? Some experts believe it is important for young people to be taught digital literacy at an increasingly earlier age – especially with the prevalence of fake news and artificial intelligence and its ability to forge fake articles and pictures. “Users of TikTok and all other social media apps must understand how to evaluate every piece of information they come across,” Lee said. “All parents worry about their child viewing harmful content on the internet. However, most leading internet providers provide extensive parental controls, including blocking and filtering unsuitable content.” Should they be encouraged to look elsewhere? For Brill, there are both benefits and challenges from using social media as a news source. He also cites the recent Reuters Institute report, which noted that TikTok users tend to look for good-news stories, avoiding the ‘doom scrolling’ found in web-based internet sites, which can have a negative impact on mental health. “The big question with social media sources, however, is that of veracity. A lack of fact checking and or acknowledgment of authoritative sources makes it difficult to identify fake stories and information. The short-form video format does not bring an in-depth analysis, where opinions are often presented as fact,” he said. “Perhaps the biggest challenge for TikTok users is with the algorithm itself. By giving more of what they like, it leads to confirmation bias that reinforces existing perceptions.” While child and behavioural expert Amanda Jenner, would encourage parents to tell their children to look elsewhere. “I am not a believer in directing children to learn through TikTok at all. Children can easily become addicted to social media and [it] can quickly escalate and [they could] be looking at other things they shouldn’t be watching. “I genuinely do feel parents need to be worried. I would encourage parents to set an age where it’s acceptable to have TikTok (over the age of 13 preferably) and have a parental control app so you can monitor and control what both they are seeing and the amount of time they spend on [it]. They need to be safeguarded.” Who knows what social network will be the next big thing but right now it’s difficult to get young people to migrate to another platform.

Ever find yourself awake, staring into space at four in the morning? Is it just a bad habit, or is there something more sinister going on? And why does it always seem to happen at 4am? “We start to experience less deep sleep after around four to five hours,” says Lisa Artis, deputy CEO of The Sleep Charity, who have partnered with Simba mattresses. And once we’re in that lighter sleep faze, we wake much more easily. If you generally fall asleep around 11pm – which is a very common bedtime, 4am wake-ups are more likely. And there are many factors leading to these inconvenient stirrings. Hormones “Sleep is guided by our internal clock or circadian rhythm. One of the most significant and well-known circadian rhythms is the sleep-wake cycle,” Artis continues. “Sleep is regulated by the levels of two hormones: melatonin and cortisol, which follow a regular 24-hour pattern. Melatonin assists you in dozing off, while cortisol helps get you up, and keeps you awake,” she explains. Keeping an eye on your hormones is important in preventing those late-night wake-ups. “Engage in calming activities before bedtime, such as reading, listening to soothing music, or practising relaxation techniques, like deep breathing or meditation,” says Dr Mariyam H. Malik, GP at Pall Mall Medical. Equally, pop your phone down for a bit. “Blue light from electronic devices can suppress melatonin production. Try to avoid screens for at least two hours before bedtime, or use blue light filters. It is best to charge them in a separate room overnight,” Malik adds. Diet Caffeine, heavy meals, alcohol, sugar, and a lack of magnesium or B vitamins could lead you to have a more disturbed night’s sleep, according to Malik. Sugar and carbohydrates may have a particular impact. “A diet high in sugar and refined carbohydrates can cause blood sugar fluctuations, leading to wakefulness during the night,” she says. “It’s unlikely you’ll feel hungry in the middle of the night if your blood sugar dips,” notes Artis, “but to reduce ungodly hour awakenings, trial alternatives for your last meal or snack of the evening. Instead of carb or sweet-based snacks, opt for protein-packed and magnesium-rich foods, like hard boiled eggs, cottage cheese, pumpkin seeds, spinach, dark chocolate, cashews, chicken thighs or turkey.” Protein can take the edge off your night-time hunger, she says, while magnesium is known to support sleep. Needing a wee Do you wake up needing to wee at the same time every night? “Try not to drink excessive amounts of fluids before bedtime,” advises Malik. “It’s important to stay hydrated, but try not to drink anything for around two hours before your usual bedtime. Go to the toilet before you go to bed to empty your bladder. ” Age and life stage “Sleep tends to become more disrupted as people get older,” Malik explains. “Sleep patterns change with age, and various factors can contribute to sleep disturbances in older adults. Some common reasons for sleep disruption in the elderly include changes in your circadian rhythm, decreased melatonin production, medical conditions or medications, and potential sleep disorders.” It can also affect women during the perimenopause. “The reproductive hormones – oestrogen and progesterone – are entwined with the sleep and relaxation hormones, melatonin and serotonin,” says Artis. “When oestrogen begins to fall before and during menopause, it can create a disturbance in the sleep-promoting hormone melatonin, meaning it can’t properly balance out cortisol. When this happens, the ability to fall and stay asleep is affected.” Recurring hot flushes, night sweats, dry skin, and low libido can signal waning oestrogen. Artis advises incorporating foods with high levels of phytoestrogens into your diet throughout the day to help with this. “Phytoestrogens imitate the natural estrogens found in your body. As a consequence, they can bind to your body’s oestrogen receptors and produce similar effects.” Try lentils, kidney beans, chickpeas, tofu, edamame, spinach, cauliflower and broccoli. Worrying Stress is not good for sleep. One study by Bupa even found that 32 million Brits wake up worrying about their health at precisely 4:05 am. The report, which surveyed 4,000 British adults, revealed that more than three-fifths of us wake up in the middle of the night. If you are finding yourself awake at all hours worrying, or waking up with stressful dreams, there are a few things that may help. “Keep a journal by your bedside and write down your worries before going to bed. This practice can help get your concerns out of your mind and onto paper, making it easier to let go of them temporarily,” says Malik. You may also want to “engage in mindfulness or meditation exercises before bedtime. Mindfulness can help you focus on the present moment, reducing anxiety about the past or the future.”

Lewis Hamilton said the right decision has been taken to cancel this weekend’s Emilia Romagna Grand Prix amid severe flooding in the region. Formula One boss Stefano Domenicali took the decision to call off the sixth round of the season in northern Italy following an emergency meeting with local authorities and race officials on Wednesday. COMMENT: Why Lewis Hamilton and Mercedes are the biggest losers from Imola cancellation “Hoping everyone in Emilia Romagna is able to stay safe and look out for each other right now,” said Hamilton, who was deeply critical of F1’s decision to travel to Melbourne amid the outbreak of the global pandemic three years ago. “Thoughts are with those affected by this tragedy and the amazing emergency services working on the ground. We were getting ramped up for the weekend and excited to get going but this is definitely the right decision. We wish we could be racing. But I know we all understand that safety comes first. I can’t wait to see you all at the next race.” Read More Lewis Hamilton and Mercedes are the biggest losers from Imola Grand Prix cancellation Will Imola Grand Prix be rescheduled?
