Use these features to improve your health and performance with better sleep and naps
When it comes to your health, there’s arguably nothing more important than sleep. And yet it’s a problem for a lot of people and an opportunity for improvement for many more. The National Heart, Lung and Blood Institute estimates that 50 to 70 million Americans have a chronic sleep condition, and at least a third of adults don’t get the recommended seven to nine hours of nightly sleep they need to thrive.
It’s difficult to optimize your sleep if you don’t know where you’re starting from. Garmin CIRQA™ Smart Band makes it easy to monitor your slumber each night, view trends over time and find ways to enhance your sleep. Let’s see how the technology works.
How do I know if I’m sleeping enough?
If you’re looking to track your daytime activity, fitness and wellness, CIRQA Smart Band provides plenty of advanced functionality. It also offers a bevy of overnight features that work behind the scenes to evaluate the quantity and quality of your sleep without you needing to do anything but rest.
The simplest, yet also one of the most significant, metrics served up by CIRQA Smart Band is sleep duration. A study published in the America Academy of Sleep Medicine found that people tend to overestimate their total sleep time by 20 to 60 minutes. CIRQA Smart Band evaluates how much sleep you actually get so that you have a more accurate picture of your true sleep habits and are notified when you need more shuteye.
What do I need to know about sleep stages?
The quality of your sleep is just as important as how much you’re getting. CIRQA Smart Band assesses movement, skin temperature and other factors to see how long you spent in each sleep stage1. Every morning, you can look in the free Garmin Connect™ app to see the amount of time you were awake (preferably zero) and in three sleep stages:
Light sleep is the gateway to deep sleep. During this stage, you regulate hormones, consolidate memories and restore mental alertness. The Smart Wake Alarm feature can detect if you’re in a light sleep before your morning alarm and gently vibrate to wake you at the optimal time, helping you feel less groggy.
Deep sleep occurs when you stop moving and your breathing and heart rate slow. During this stage, it can be harder to wake you. Deep sleep supports muscle recovery, immune function, and heart and brain health.
Rapid eye movement (REM) sleep is the final stage of each sleep cycle. It’s likely when you regulate emotions, process things you’ve learned and protect against cognitive decline.
What does my sleep score mean?
Sleep duration and the time spent in each sleep stage are just a few of many metrics that CIRQA Smart Band utilizes to calculate a nightly sleep score. Ranging from 0 to 100, this number gives a convenient, at-a-glance view of your overall sleep quality the night before. Through the Garmin Connect app, CIRQA Smart Band offers insights into which habits might have contributed to a high or low score.
If you were very active the day before and not very stressed, that could be why you slept well. Whereas if you drank alcohol or did an intense late workout, perhaps that’s why your sleep was less than optimal. These explanations can help you make beneficial choices and create helpful habits that contribute to better sleep.
How can I benefit from sleep coaching?
Garmin sleep coach on CIRQA Smart Band considers five factors to further evaluate your sleep and provide personalized recommendations. Taking age, short- and long-term activity levels, recent sleep history, naps and heart rate variability (HRV) into account, it offers guidance on how you can further improve your sleep quality.
For example, you might need to go to bed earlier or wake up later to get more total sleep time, which typically ranges from seven to nine hours. Or perhaps you’d benefit from taking a nap to supplement insufficient slumber last night. Sleep coach helps make course corrections that help you achieve your lifestyle aims and performance goals by improving your rest.
How long should I nap for, and when is the best nap time?
Napping is a great way to catch up on sleep. Taking a brief snooze can help improve focus, boost energy levels, enhance recovery and more. CIRQA Smart Band detects when you’re napping and logs the same data as during your nightly sleep. You can then view recommendations for dialing in your nap schedule and duration via the Garmin Connect app. Logged naps also impact your Body Battery™ score and inform sleep coach advice.
How does sleep affect my overall health?
Sleep status can impact physical and mental performance, recovery, and overall health. When you wear CIRQA Smart Band consistently, it measures five core metrics overnight:
- Heart rate variability
- Heart rate
- Pulse oximetry
- Respiration rate
- Skin temperature
Over time, these measurements provide a baseline that’s presented to you as Health Status in Garmin Connect2. You’ll be notified anytime you’re out of range in any area, prompting you to improve your sleep habits and get your Health Status back on track.
How can sleep tracking improve women’s wellbeing?
Hormone changes during your cycle can cause your skin temperature to fluctuate. CIRQA Smart Band tracks these changes overnight, allowing you to be more informed about your ovulation cycle and better predict your upcoming period.
How do I wear Garmin CIRQA Smart Band while sleeping?
With a low profile designed to enable undisturbed sleep, the comfortable CIRQA Smart Band can be worn on your wrist or, with an optional accessory, on your upper arm overnight.
With Garmin CIRQA Smart Band, you can learn more about your sleep, get advice on how to improve it and see how you’re progressing, all without a monthly subscription. You’ll rest easy while CIRQA Smart Band does the hard work.
Better sleep is just one part of the wellness puzzle. CIRQA Smart Band offers a broader view of your health and fitness that we’ll explore in upcoming posts. Garmin also has a full lineup of smartwatches to support your goals.
