Sleep is a crucial aspect of our overall health and well-being, and understanding the factors that can influence its quality is essential. One such factor is temperature, which can play a significant role in the sleep process. Research has shown that our body's temperature fluctuates during sleep, and these fluctuations can impact the quality of our rest. With the latest update to our sleep tracking app, Pillow, you can now effortlessly track your temperature during sleep, empowering you to optimize your sleep environment and improve your overall sleep quality.

The Science Behind Sleep and Temperature

Numerous scientific findings have established the connection between sleep and temperature. Our body's core temperature follows a circadian rhythm, naturally decreasing during the night to reach its lowest point in the early hours of the morning (Kräuchi, 2002). These temperature fluctuations have been linked to sleep stages and the overall quality of sleep.

Ambient temperature, or the temperature of our sleep environment, plays a significant role in determining the quality of our sleep. Studies have shown that ambient temperature affects sleep stages, particularly slow-wave sleep (SWS) and rapid eye movement (REM) sleep (Okamoto-Mizuno & Mizuno, 2012). An overly warm sleep environment can lead to reduced SWS, while excessively cold temperatures can cause disruptions in REM sleep (Kräuchi, 2007).

Optimizing your sleep environment's temperature can significantly impact your sleep quality, as it facilitates the natural fluctuations in core body temperature that promote restful sleep. By monitoring and understanding these fluctuations with Pillow, you can make informed decisions on adjusting your sleep environment to enhance your sleep quality.

Introducing ASMR sounds to Pillow, our sleep tracking app, was no easy task. We wanted to make sure we offered a variety of compositions that catered to different personal preferences. After much research and testing, we're excited to announce that ASMR sounds are now part of our Sleep Aid library. So, if you're struggling to fall asleep, this might be the solution you've been looking for.

ASMR, or Autonomous Sensory Meridian Response, is a tingling sensation that starts at the scalp and moves down the spine. It's triggered by specific auditory or visual stimuli, like gentle, soothing sounds, which can help relax the mind and induce a sense of calm. Research has found that ASMR can reduce stress, anxiety, and insomnia, leading to improved sleep quality. One study published in the journal PLOS ONE showed that participants who experienced ASMR reported increased feelings of relaxation, decreased heart rate, and better sleep quality. Another study in the journal PeerJ found that ASMR could have potential therapeutic applications in reducing stress and anxiety.

We've carefully curated a collection of ASMR themes for you to explore, such as Scissors, Keyboards, Water Splashes, Plastic Wrap, and Paper. Whether you find the rhythmic snipping of scissors or the gentle rustling of paper relaxing, there's something for everyone.

Pillow's ASMR sounds section is now live, and we can't wait for you to try it out. We're confident that these soothing sounds can help improve your sleep experience. Download the app, dive into the new ASMR section, and let us know what you think. We'll continue to work hard to enhance your sleep tracking experience and bring you the tools you need for better rest.

Are you tired of waking up groggy and unrested? Has your partner been complaining about your snoring? Pillow now has a brand new feature designed to help you better understand your snoring.

The Importance of Snoring Trends

Tracking your snoring duration is essential for understanding your sleep quality and overall health. Chronic snoring can lead to sleep deprivation, strained relationships, and even serious health conditions like sleep apnea. By monitoring your snoring habits, you can identify patterns and make necessary changes to improve your sleep. And now, with Pillow's Snoring Trends, you'll have a new tool you need to take control of your nighttime noises.

How it works

Snoring Trends allows you to visualize your snoring habits on a weekly, monthly, and annual basis, providing valuable insights into the patterns of your snoring. Additionally, you can compare your snoring duration with a number of health and sleep-related metrics, such as sleep quality, steps, body weight, and more. This comprehensive view of your health data helps you make informed decisions about your sleep environment, bedtime routine, and lifestyle choices to reduce snoring and improve your overall sleep quality.

What sets Pillow's Snoring Trends apart from other sleep trackers is its ability to show you which hours of the day you tend to snore more. This unique feature can help you pinpoint specific factors that may be contributing to your snoring, such as stress, diet, or sleep position. By understanding the times when your snoring is most prevalent, you can make targeted changes to your routine and sleep better than ever before.

To view your Snoring Trends, you'll need to record a sleep session manually before going to sleep. This ensures that the app captures accurate data about your snoring throughout the night. Don't worry, the recording process is simple, and the app will guide you through each step.

Once you've recorded your first sleep session, the Snoring Trends feature will become available in the Trends section of the app. You can then explore your snoring data and discover patterns to help you make informed decisions about your sleep habits.

By tracking your snoring duration over time, you can make informed decisions about your sleep environment, bedtime routine, and lifestyle choices to reduce snoring and improve your overall sleep quality. Start using Snoring Trends tonight and unlock the secrets to a better night's sleep.

Sleep stage trends

It's a well-known fact that our sleep is not the same throughout the night. Scientists have categorized and named the distinct stages we go through during sleep, and every one is essential. Pillow's sleep stage analysis is a first step towards being more aware of how you slept and how much time you spent in each sleep stage.

Pillow's latest update introduces a big update that can help you discover how these sleep stages change over time. The trends tab now includes three new sections, one for each sleep stage with helpful weekly summaries. If you want to delve deeper, Pillow offers a rich detail view where you can review your sleep stage trend on a weekly, monthly and annual basis. What's more, you can compare the time spent on each sleep stage with various categories from Apple Health like, Steps, Caffeine consumption, Dietary Calories, and more.

Sleeping heart rate trends

Another important aspect of sleep is our heart rate. Pillow 4.7 brings a new section that helps you track your average heart rate during sleep. This trend comes with a quick weekly summary and a detail view that helps you track your average heart rate during sleep on a weekly, monthly and annual basis. This is also a trend that you can compare with various Apple Heath categories and discover potential correlations.

A huge update for Pillow's audio recording feature.

As you know, you can let Pillow record sounds during sleep like snoring, sleep talking or any other environmental sounds that could be affecting your sleep. Pillow didn't have a way to categorise these sounds but now it does!

Using machine learning, Pillow can now automatically categorize all your sound recordings under specific categories related to sleep. The categorization takes place using on-device intelligence. Pillow doesn't need to send anything outside your device for this analysis which is great for your privacy. This feature doesn't need an internet connection!

We've redesigned the audio recordings section so that you can get a quick overview of the sounds that Pillow recorded during sleep and compare their duration across sleep sessions. This also opens up a new dimension in sleep tracking that we will be introducing in the next versions of Pillow to provide significant insights like the duration of snoring over time and many more.

Our sound categorization algorithm has been specifically engineered for sounds during sleep, and we're very proud of how well it performs. However, it can continue to evolve and adapt based on your feedback. If you believe that Pillow hasn't categorized a sound under the right category, you have the option to change its category. You even have the option to disable any categories that you don't care about to let Pillow keep track of the categories you care about.

If you have any audio recordings that were recorded before this update, you can let Pillow categorize all of them automatically. Simply go to the sleep session and tap to view your audio recordings.

As always, Pillow cannot record audio if you are tracking sleep automatically by wearing your Apple Watch. To let Pillow record sounds during sleep, you must track your sleep manually by pressing "Start" in Pillow before sleep. You can do that by using your Apple Watch, iPhone or iPad. If you use the Apple Watch, please remember to start the sleep session from your Apple Watch and place your iPhone on the nightstand next to you because Pillow will use the microphone of the iPhone to record audio.

Lastly, if you want to help us improve Pillow's categorization algorithm, you have the option to send us any miscategorized sound anonymously.
