– John Lopos, CEO, National Sleep Foundation

In today’s busy world, it’s easy to get lost in the hustle and bustle of our lives. We understand the benefits of prioritizing sleep, but the to-do list is never-ending and can cause our stress levels to go up.

This has been highlighted in a recent study from one of the world’s leading sleep organizations, the National Sleep Foundation (NSF), finding that during the pandemic, more people in the US have been sleeping longer, but the quality of that sleep has suffered.

In fact, the NSF believes one of the biggest challenges facing the public is the need to keep prioritizing sleep for our health and well-being. Embracing the continuously growing category of sleep technology can help. From smart environmental controls to smart sleep tracking, cutting-edge and evolving technologies are reinventing and improving the sleep experience for the public. Sleep technology is coming to the industry forefront as consumer brands — like Samsung — are prioritizing sleep-related capabilities within their products.

To find out more about the impact sleep technology can have on improving sleep health, we sat down with NSF CEO John Lopos to take a closer look at the intersection of sleep and technology.

Managing Routines and Tracking Progress

According to the NSF’s 2022 Sleep in America^® Poll, there’s a significant opportunity to improve daily activities that are associated with positive sleep and health outcomes. Eating your meals at a consistent time, the amount of physical activity completed in the day, and even the level of light exposure during the day and around bedtime, all impact sleep health and are manageable.

The NSF has specific guidelines and recommendations for positive sleep health, and this, Lopos said, is where “technology can be a thread that runs through our sleep experience. It helps us as a reminder, a facilitator, a communicator and a tracker, and can play a role in helping meet the NSF’s recommendations for better sleep — both while awake and asleep.”

Keep up with your daily workout routine with Galaxy Watch4 for a good night’s sleep

Controlling Your Sleep Environment

The right kind of light exposure during the day and night can make the difference between a good night’s sleep and a restless night. With nearly 60 percent of Americans saying they look at screens very often or somewhat often in the hour before bed or while in bed before sleep, it’s no wonder sleep quality is on the decline as light from phone, laptop and TV screens can significantly impact sleep.

And while technology can be the culprit when used inappropriately, like viewing screens too close to bedtime, it can also be part of the solution. “As people prepare for sleep, technology can help establish a sleep-friendly environment, help with a wind-down process that makes people feel more calm and relaxed, and then — and this is important — take its place in the background without disrupting a person’s sleep,” noted Lopos. A good example of this is the SmartThings functionality¹ which allows users to program a pre-set time to turn off the bedroom TV and turn down the lights as part of a bedtime routine to help prepare them to sleep and create better sleeping conditions throughout the night.

Adjusting Sleep Patterns

While sleep technology can play a meaningful role and help with long term health benefits, it can also help users adjust sleep patterns in the near term. Whether “springing forward” or “falling back”, Daylight Saving Time can have a significant impact on sleep. To help prepare, the NSF provides a number of tips including prioritizing natural daylight exposure, adjusting your clocks the night before the time change, and in the week leading up to a clock change, going to bed a little earlier each night to adjust your sleep schedule. The NSF also encourages the practice of relaxation techniques to help get a good night’s sleep every day, including during a time change disruption. The Galaxy Watch4 and the Samsung Health app can help with this by empowering users to manage their mindfulness through its breathing, meditation and stress monitoring capabilities.²

Better Sleep Today and Tomorrow From Samsung

It’s with this understanding of the power of sleep technology that Samsung has introduced features on the Galaxy Watch4 that are empowering users to track and meet wellness goals and help users work toward a better night’s sleep.

For example, the new sleep coaching program on the Galaxy Watch4 helps users achieve better sleep habits and achieve their sleep goals.² The Samsung program assigns one of eight sleep symbol animals representing the user’s sleep type after tracking sleep patterns over seven days and completing two related sleep surveys. Then, it guides users through a four-to-five-week coaching program that includes missions, checklists, guidance and reports to support users as they work towards improving their sleep health.

With wearable devices now a regular part of many people’s lifestyles today, tracking and understanding elements of sleep are more common than ever — and the NSF wants to see even more access to sleep technology, believing that the sleep technology industry is going to ride new waves of collaboration and knowledge sharing. “We’re going to see even more integration across wearable and connected devices, lifestyle and wellness platforms and home goods,” Lopos affirmed. “People’s choices and feedback will confirm there’s lots of room for products and services that use sleep technology.”

The future of sleep technology is promising, and Samsung is committed to developing and enhancing their sleep offerings and capabilities with the sleep expertise of the National Sleep Foundation.

Samsung Electronics today announced a new update to the Galaxy Watch4 and Galaxy Watch4 Classic, continuing its commitment to helping users reach their health and wellness goals and express their personal style. Users can expect new improvements like advanced interval training designed for any cyclist or runner, a new sleep coaching program and new body composition¹ insights. Galaxy Watch4 users will now have even more ways to customize their look with upgraded watch faces, and a new line of stylish straps.

“We understand the growing needs of smartwatch users, and are committed to guiding our Galaxy Watch4 series community on their unique wellness journeys with our latest update,” said Janghyun Yoon, Executive Vice President and Head of Software Platform at Mobile eXperience Business, Samsung Electronics. “We are excited to continue this effort as part of our wider initiative to redefine holistic wellness through expanded experiences and new innovations.”

The latest body composition update gives users even more insight into their health progress. Samsung Health will also be providing body composition insights powered by Centr,² a digital fitness program curated by Chris Hemsworth, to help users transform their health, fitness and mindset. In addition, Galaxy Watch4 users will receive a 30-day trial³ for full and unrestricted access to Centr. 

Whether you’re just looking to get active or training for an upcoming race, Samsung’s new interval target feature for runners and cyclists lets them pre-set the duration, distance and number of sets for their workout. From there, Galaxy Watch4 guides them through a custom intensity training session with a series of high-intensity workouts interspersed with low-intensity workouts, making for an impactful and targeted workout every time.

We are continuing our collaboration with top-ranked apps⁴ like adidas Running and Strava to help users power through their exercise.

Work Towards a Better Night’s Sleep

Building on Galaxy Watch4’s robust sleep tracking capabilities, the new sleep coaching program helps users develop better sleep habits. By tracking sleep patterns over seven days and completing two related sleep surveys, the program assigns one of eight sleep symbol animals representing the user’s sleep type. Then, it will guide users through a four to five week coaching program that includes missions, checklists, sleep-related articles, meditation guidance and regular reports to support users as they work towards improving their sleep quality.

When it comes to waking up refreshed, a peaceful and quiet environment is key to achieving a healthy rest as well. Galaxy Watch4 recognizes when users fall asleep and automatically turns off Samsung SmartThings enabled lights to help create better sleeping conditions.⁵

Deeper Insights for a Healthier Heart

Combined with the advanced BioActive Sensor technology and Samsung Health Monitor app,⁶ Galaxy Watch4 measures both blood pressure⁷ (BP) and electrocardiogram⁸ (ECG), allowing users to monitor their heart health anytime and from anywhere. Since the first introduction in 2020, Samsung Health Monitor app is currently available in 43 markets globally, expanding to 11 more in March, including Canada, Vietnam and South Africa.

Greater Selection of Matching Straps and Watch Faces

The new Galaxy Watch4 update makes the wearable experience even better, from the inside out. Users can further customize their watch face with additional colors and digital clock fonts that make the watch truly their own. Also, new strap colors⁹ such as burgundy and cream, and the new fabric band and link bracelet will be available for a more personalized look.

Committed to Expanding Compatibility Within the Android Ecosystem

In 2021, Samsung and Google introduced co-developed Wear OS Powered by Samsung, bringing smoother connections across Android devices and seamless access to more apps via Google Play including Google Maps, Google Pay and YouTube Music. Coming soon through an additional update, users will be able to stream music over Wi-Fi or LTE from the YouTube Music app on their Galaxy Watch4. This means that users can leave their phone behind and still enjoy their favorite artists as they work out on-the-go.

Additionally, Google Assistant will be available on Galaxy Watch4 series in the coming months. With access to both Bixby and Google Assistant, consumers will be equipped with advanced voice assistant functionality to meet their various needs.

Users can also now install their favorite smartphone apps¹⁰ on their Galaxy Watch4 during initial setup with one tap, creating a seamless experience across devices right out of the box.

Availability^{11, 12}

This software update will be available via the Galaxy Wearable app for Galaxy Watch4 and Galaxy Watch4 Classic starting the day of the Unpacked – February 10^th KST. Users can purchase the new watch straps beginning late February.
