Binge-watching or sleep-wrecking? How your favourite TV shows are sabotaging your sleep
Image: KoolShooters /pexels
We all love a good bedtime binge. A familiar show, a cosy blanket, and maybe something to sip on, it's the perfect way to unwind, right?
Not quite, according to sleep experts and new research that shows our favourite late-night viewing choices might be stealing more than just our time.
They could be messing with our sleep in a big way.
Not all TV is created equal, at least not for sleep
A recent study from Premier Inn surveyed 2,000 Brits to find out how their TV habits affect their sleep. The results are eye-opening: the genre of show you choose before bed has a direct link to how well and how long you sleep.
It turns out that tuning into calming content like sports documentaries, kids' shows, and nature documentaries (think Planet Earth or Drive to Survive) can actually promote better rest. Nearly 7 out of 10 people who watched sports documentaries before bed rated their sleep as 'very good' or 'fairly good'.
On the flip side? Fans of true crime, horror, and intense thrillers are sleeping significantly worse, with true crime topping the list of genres most associated with poor sleep.
'Our brains don't just stop processing once the TV turns off,' explains Dr Lindsay Browning, a chartered psychologist and sleep expert. 'What you watch before bed can leave your mind racing or even trigger stress responses, especially when it involves suspense, violence or real-life trauma.'
Shows that help you sleep better
If you're struggling to fall or stay asleep, it might be time to trade your serial killer obsession for something a little softer. Based on Premier Inn's findings, here are the genres most likely to support a restful night:
TV genres that had noticeably higher good sleep scores: Sports documentaries (Drive to Survive) 69%
Kids & family shows (Bluey) 66%
Legal drama (Suits) 65%
Nature documentaries (Planet Earth) 62%
Talk shows (Graham Norton) 62%
These shows often feature predictable pacing, low-stakes conflict or soothing visual elements that help the brain relax, rather than amp up.

It might feel like the latest true crime doc or spooky thriller is just your guilty pleasure. But it could be costing you quality rest.
According to the study: 31% of true crime fans rated their sleep as ' poo r'
45% reported feeling tired at least four days a week
Horror and crime dramas

While gripping, shows like "Making a Murderer", "The Staircase", "Squid Game" and "Stranger Things" are loaded with suspense, fear and high cortisol triggers. And that's not great news for your nervous system right before bed.
'Cortisol, our stress hormone, can spike while watching something intense, and it can take hours to return to normal levels,' says Dr Michael Breus, also known as "The Sleep Doctor". This disrupts our body's natural ability to transition into sleep mode.'
Why screen time matters more than we think
This research isn't just about what's on the screen, but how much time we're spending in front of it. According to the study, almost half of the participants watch TV for 3-4 hours each night a habit that's becoming the norm in many households.
When you mix extended screen time with stimulating content, it's a double hit to your sleep cycle. The blue light emitted by screens suppresses melatonin production (the hormone that helps you sleep), and intense emotional content keeps your mind wired long after the credits roll.
How to make TV work for you, not against you
The good news? You don't have to give up TV altogether. Here are a few lifestyle tweaks that could help:
Time it right: Cut off TV at least 30-60 minutes before bed to give your brain time to wind down.
Choose sleep-positive genres: Opt for light-hearted, slow-paced or educational content.
Dim the lights: Reduce screen brightness and room lighting in the evening to help your body recognise
it's
bedtime.
Set a viewing limit: Instead of binge-watching, cap your watching time at one or two episodes.
Try audio alternatives: If TV is your go-to comfort, consider switching to a calm podcast or audiobook before bed.
The way we unwind matters more than we think.
In a world where 'just one more episode' feels like self-care, it's worth asking whether that final click is doing more harm than good.
Sleep is a non-negotiable and protecting it starts with what we choose to invite into our heads each night.

Meet the medical doctor who now hosts Sunnyside Up on Southside FM
Dr Pubern Padayachee co-hosts Sunnyside Up on Southside FM. Image: File IN A WORLD where passions often clash, few individuals manage to blend two seemingly divergent careers. Dr Pubern Padayachee, born and raised in Chatsworth's Arena Park, is one such individual. A doctor, award-winning model, and now radio presenter, Padayachee is captivating listeners with his new breakfast show, Sunnyside Up, on Southside FM from Monday to Friday from 6am to 9am. Padayachee's journey began at the Nelson Mandela School of Medicine but beneath his white coat lay a young man eager for creative expression. With a background in Western music and Indian classical dance, he has always found joy in creativity, whether it be through cuisine or the performing arts. "I was always academic and musically-inclined even throughout school," said Padayachee. Pubern Padayachee competed in Mr International in Indonesia. Image: Suppied Video Player is loading.

Next Stay Close ✕ "Medicine was a first love but there was always a creative side to me that also had to be satisfied. When I was approached at a shopping mall, while with my mum to enter my first pageant, I remember her being supportive only after I promised to not let it affect my studies. It was seen as a hobby, not as a career path. "I was fortunate to win both Mr India South Africa 2004/2005 and Mr South Africa International 2013. It launched a parallel career in modelling, presenting and acting. I did multiple theatre productions, The Chalo Cinema franchise from 2005 to 2012, and wrote and produced theater productions during my medical school years. "I remember long days spent during school hours and between productions. It wasn't always received well by the conservative medical field and the directors and agents back then, and I found myself working twice as hard to prove my dedication to both fraternities. "I really had to fight to keep pursuing both fields as it was unheard of, for anyone at that time being equally passionate about both. My dedication to ensuring I didn't let the baton drop allowed me to win them over and be recognised for doing both simultaneously. Now society is a little more welcoming and accepting and I'd like to think I played a small hand in bringing that to the present." He said pageants for men were also considered taboo among some circles, and the stigma of intellect and beauty never being able to co-exist in the professional and entertainment realm prevailed. "I pushed the boundaries and proved to be the exception to the norm. I gained respect for wearing the sashes with pride, and using them as platforms into successful entertainment and philanthropic fields while still being dedicated to my patients." Padayachee went on to present for Eastern Mosaic which, he said, allowed him access into every Indian South African home. "And years later, I began presenting on the Expresso morning show, making me a national household name. These two experiences taught me valuable tools in the trade." He said having won both pageants also meant doors opened for him in India and Asia. "I relocated for some time until I returned to South Africa to resume medicine during Covid-19." Since he was away from the media scene for a while, the environment had become different to when he was involved. "I've re-entered after a long hiatus because I was tired of sighing deeply and shaking my head every time a vapid influencer expressed an undignified thought on a public platform. I was tired of watching impressionable youth spend hours mindlessly following and mimicking the actions of a 'public figure' to the detriment of their pockets, their time and their future. "We all think that it is not our problem or none of our business, until you start dealing with it in real life. Leaving culture unpromoted, morals unattended, and work ethics not reinforced will ultimately lead to a community that is weak. I was waiting for someone to come and save the public platforms. Someone trending and fresh to take on the fight, but when I look around, I think popularity was prioritised above talent. I had the credentials, experience and urgency, and it was my time to re-step in one way or another. "I am excited to use this new radio cap to bring back the importance of media and entertainment in shaping people's thoughts and views and hopefully provide formidable role models." His co-host on Sunnyside Up is Thashriya Naidoo. "She is from a different generation to me but when you listen to our show, it's a seamless blend of current South African, Indian and international culture that's ageless and entertaining. She is talented, wise beyond her years and is also making great sacrifices on her end to make the show relevant and successful. We thankfully gelled from day one and have an on-air chemistry that would be difficult to fake. "We pride ourselves in having a range of music genres from golden oldies to the latest Tamil, Telugu and English songs and our content is creative while being current." Padayachee said he prioritised giving back to the listeners. "I grew up when Indian radio and TV stations really got involved with the community. That's missing today and it is a pivotal gap that I'm trying to fill. There's a real sense of family and friendship that exists on Southside FM and I'm excited to become a part of their daily mornings. "There are plans for a youth club, community events, listener challenges and games and freebies. Everything you need from the new breakfast kids on the block." The response since joining the station, he said, was overwhelming. "There are new listeners joining in every day, even extending as far as Johannesburg and the UK." To add another feather to his cap, Padayachee said due to being featured on multiple culinary platforms, and having a passion for food and flavours, was writing a recipe book to document all his kitchen adventures.

'As artistic director, my mission is to show that joy, community, creativity and fashion are all still connected. That humanity, culture and connection are still the access points. They stand where I stand, and I'm honoured to invite a whole bunch of people to stand Off the Wall with us.' This move follows the earlier launch of her beauty brand, 'Not Beauty', earlier this year. The range debuted with three lip gloss shades, which are 'In The Flesh', 'Strawberry Jelly' and 'Quartz' She first sold her lip gloss range at pop-up shops during her 'Grand National Tour' with Kendrick Lamar. SZA has been wearing her own products long before releasing them. 'I'm not a beauty maven, but I know lips. I know what I like, and I'm diligent about finding the best quality ingredients,' she told "Vogue". Following her success in beauty, SZA's collaboration with Vans marks another significant step in her creative path. The 'SOS' singer's new role is also a big step for Vans. The brand has a long history of working with creative people, and teaming up with her brings a fresh point of view. They intend to combine her personal style with Vans' skate and streetwear aesthetic, all while upholding the brand's core values of originality and authenticity.

The post made it clear she was standing firm on her stance. Without dismissing freestyling as an art form, she appeared to stress that her focus is on creating polished, intentional music rather than spur-of-the-moment verses aimed at creating viral moments. 'I make real music for real music lovers, take that however pleases you,' she wrote.

The rapper further elaborated that the album explores themes of overcoming fears, confronting challenging situations, and ultimately forcing oneself to face difficulties.
