How Samsung Is Tackling Sleep Apnea to Energise Your Days

Millions worldwide suffer from sleep apnea, but 80% of sufferers[1] don’t even know they have it. This serious condition causes people to pause breathing while asleep, potentially disrupting oxygen supply, lowering sleep quality, and leading to health complications including hypertension and stroke. Despite these risks, the disorder largely goes unnoticed because getting a diagnosis usually requires time-consuming and costly in-lab sleep studies.

To mark World Sleep Day 2026, a global study of Samsung Health users[2] is shedding new light on the true extent of the condition and the disruptive impact it has on your sleep. Aligned with this year’s World Sleep Day theme, “Sleep Well, Live Better,” Samsung is turning the invisible signs of sleep apnea into actionable insights through its Galaxy Watch series, helping those affected improve their sleep habits and overall health.

How Does Sleep Apnea Impact Your Sleep?

The report found that 23% of study participants are at risk of sleep apnea.

“The microarousals and awakenings that follow breathing pauses fragment your sleep,” explains behavioral sleep scientist Dr. Vanessa Hill. “Those occurrences can prevent the brain from staying in the REM and deep sleep stages necessary for cognitive and physical restoration.”

The report shows these constant disruptions take a direct toll on sleep duration and quality, leading to:

  • Reduced REM Sleep: Participants with moderate to severe sleep apnea indicators detected by their Galaxy Watch got around four minutes less rapid eye movement (REM) sleep, the phase where our brains process emotions, consolidate memories and cement learning. Without enough of it, people can experience mood instability and memory problems, impacting performance at work and overall well-being.
  • Less Deep Sleep: Sleep apnea also robs sufferers of deep sleep, approximately eight minutes less per night, on average. This is the body’s critical physical restoration phase, where growth hormone is released, muscles are repaired, and your immune system is activated. Losing out on deep sleep is why you may feel physically exhausted, have slower recovery times, and get sick more often.
  • Frequent Nightly Awakenings: Study participants with signs of sleep apnea also woke up regularly during the night and stayed awake around four minutes longer. These interruptions derail the sleep cycle, locking you into lighter, less restorative stages and making next-day exhaustion inevitable, no matter how long you slept.
  • Shorter Sleep Duration: Overall, people with a higher likelihood of sleep apnea averaged around 12 minutes less sleep. While this loss may seem minor, it can have a significant impact on overall sleep quality as your sleep cycle gets fragmented throughout the night.

Why It Matters: “Even a small loss in sleep duration is compounded by a larger loss of sleep quality,” said Dr. Hill. “This can be the difference between simply being ‘in bed’ and getting restorative rest, which could be why people feel so tired the next day.”

Dr. Hill also advocates a multidimensional approach to sleep health. “Sleep apnea affects many dimensions of sleep, duration, quality, sleep efficiency and even daytime fatigue,” she stated. “They together help determine our health and functioning.”

With sleep apnea shown to impact all aspects of sleep and lead to other health complications, detection is an essential first step in the fight against the condition.

How Does Galaxy Watch Help Detect Signs of Moderate to Severe Sleep Apnea?  

For years, sleep apnea has been difficult to detect due to the need for inconvenient hospital tests. However, Samsung offers at-home detection with a first-of-its-kind Sleep Apnea[3] feature on your Galaxy Watch.

  • How It Works: Users simply track their sleep with a compatible Galaxy Watch[4] for more than four hours over two nights within a ten-day period. Available through the Samsung Health Monitor app, the Sleep Apnea feature enables users to proactively spot signs of the condition. Initially launched in Korea, the feature has since received De Novo authorization from the U.S. FDA and is now available in 78 markets[5] worldwide and counting.
  • The Technology: Leveraging the Galaxy Watch’s BioActive Sensor, the feature tracks blood oxygen levels to determine when the user stops breathing (apnea) or is not breathing enough (hypopnea). Based on this data, the feature estimates the user’s Apnea-Hypopnea Index (AHI), which indicates the severity of obstructive sleep apnea (OSA).
  • From Awareness to Action: By detecting signs of sleep apnea early, the feature provides the data needed for an informed consultation with a medical professional. In addition to tackling sleep apnea, your Galaxy Watch can help you build habits for better holistic sleep health. Features include the Sleep Coaching program for detailed analysis and tips on how to improve sleep quality and Bedtime Guidance,[6] which recommends your optimal bedtime to ensure you consistently get enough sleep.

“For years, the inconvenience of an in-lab clinical sleep study has been a barrier to diagnosing sleep apnea,” added Dr. Hill. “Wearable technology such as Galaxy Watch is a breakthrough because it democratizes that first step. It allows people to gather meaningful data from their own beds, providing a starting point for a conversation with a healthcare professional.”

YouTube expands parental controls in Ireland and beyond

Today, YouTube announced a new set of tools and content standards designed to give parents more control over their teen’s viewing experience. New research also reveals that 77% of EU parents using YouTube’s supervised accounts agree the content their child views is age-appropriate, and 73% agree the tools give them confidence in a safer digital environment for their child.

Dr. Garth Graham, Global Head of YouTube Health, said:

“We believe in protecting kids in the digital world, not from the digital world. That’s why providing effective, built-in tools is so essential, as parents play a critical role in setting the rules for their family’s online experiences.”

“After feedback from parents and guidance from independent experts, we’re equipping families with even more tools and protections that are right for them. This builds on a decade of investments to create a healthy experience for young people on YouTube.”

Key updates shared in a new YouTube blog post include:

  • Additional controls for mindful teen viewing: Parents can now help teens be even more intentional about how they watch, with a control to set the amount of time spent scrolling Shorts. And soon, they will also have the option to set the timer to zero – an industry-first that gives parents flexibility to, for example, set the Shorts feed limit to zero when they want their teen to use YouTube to focus on homework, and change it to 60 minutes during a long car trip to be entertained. Parents will also be able to set custom Bedtime and Take a Break reminders, building on the existing default-on wellbeing protections for teens.

  • Making it even simpler to get the right experience for the right age: A new sign-up process will make it easier for parents to create a new kid account and switch between family accounts in the mobile app, depending on who’s watching with just a few taps. This makes it easier to ensure that everyone in the family is in the right viewing experience with the content settings and recommendations of age-appropriate content they actually want to watch.

  • A blueprint for high-quality teen content: YouTube is introducing new principles to steer teens toward age-appropriate and enriching content. Developed with the Center for Scholars & Storytellers at UCLA and supported by experts from University College London, the APA and Boston Children’s Hospital, these principles will guide YouTube’s recommendation system to raise high-quality videos from creators in Ireland and beyond.

Alongside the new high quality principles for teens, YouTube unveiled a Creator Guide, developed in

partnership with the streaming service’s Youth & Families Advisory Committee and supported by Save the Children International.

Rebecca Smith, Global Head of Child Protection, Save the Children International, said:

“We are pleased to partner with YouTube on the launch of their new Creator Guide, which equips content creators with the knowledge and tools to stay informed, educated and safe online. With the help of this guide, not only can creators make the most out of their own digital experience, but they can support fellow creators as well. This initiative reflects YouTube and Save the Children’s shared commitment to fostering a safer digital environment for all.”

Professor Peter Fonagy, Head of the Division of Psychology and Language Sciences at UCL, said: “The mental health of children and young people is a global concern, and in the digital age the content teens encounter online can have both positive and negative impacts. These YouTube Teen Quality Principles give creators a practical, research-informed roadmap for making videos that are developmentally appropriate, emotionally safe, and genuinely supportive of young people. UCL was delighted to partner on this programme to bring evidence-based insights on adolescent development, helping ensure creators understand their wider responsibility to help teens thrive while minimising potential harm.”

These updates will be rolling out starting today and will expand globally over the coming months.

New YouTube/Ipsos research: A survey conducted by Ipsos for YouTube in August 2025, found that:

  • In the EU, 77% of survey respondents who are parents and have used YouTube supervised account tools said they agree that the content their child views on their supervised YouTube account is appropriate for their age.

  • In the EU, 73% of survey respondents who are parents and have used YouTube supervised account tools said they agree that YouTube’s supervision tools give them confidence that their child is accessing a safer and more controlled digital environment.

Creating For Teens on YouTube: Teens often look at creators for guidance as they grow and navigate the world. Together with global experts, we created a new guide of principles to help you make content that’s responsible, fun, and positive while avoiding harmful qualities so teens can build confidence, connection, and community online. These are the High Quality Principles included in the Creator Guide, to inspire teens to explore, learn, and feel good about themselves:

  • Joy, Fun And Entertainment: Show humor and warmth that lift teens’ moods like a day-in-the- life video or funny, self- accepting outtakes.

  • Curiosity and Inspiration: Encourage exploration through creative tutorials, behind-the-scenes demos, or new hobbies that are easy to try.

  • Deepening Interests and Perspectives: Create deeper dives into subjects teens love, like music, gaming, or fashion, and show process, not just outcomes.

  • Building Life Skills and Experiences: Offer relatable guidance for real-life moments, like teamwork or budgeting, to help them prepare for the future.

  • Credible Information that Supports Well-being: Share accurate, age-appropriate information. Use trusted sources and avoid spreading misinformation.

The Creator Guide also includes a series of top tips for creators to be positive online role models. These include:

  • Set the tone for your community: Speak up against hate, avoid unproductive conflict, and challenge misinformation, while distinguishing between fact and opinion.

  • Create a safer space for everyone:  Encourage teens to revisit their privacy settings, curate their feeds, and unfollow accounts that harm their well-being.

  • Support teen resilience and well-being: Whether it’s from pressures to succeed, to look a certain way, or to fit in with their peers, teens can face an overwhelming amount of stress, leading to burnout and other negative outcomes. Your content can give teens the right tools to build resilience and combat stress.

  • Help teens thrive on and offline: Your impact as a creator doesn’t stop when teens log off. By showing creative ways to connect with friends and family and prioritising healthy habits, you remind them that balance matters.
