Quell measures and tracks how much sleep you are getting.
Good sleep is essential to maintaining health. Chronic pain is a common cause of poor sleep, which is why many people with chronic pain do not get a good night’s rest and feel tired upon awakening. Inadequate sleep can worsen chronic pain, which can trigger a vicious cycle of decreased activity during the day, less sleep, and even worse pain. It is essential that you get as much high-quality sleep as possible.
Quell measures and tracks how much sleep you are getting and presents this information to you via the Quell Relief app. Quell also analyzes your body movements and position while sleeping. This sleep data is meant to help you optimize healthy sleep. It is not intended for use in the diagnosis, mitigation, treatment, or prevention of sleep disorders or other related conditions.
The table below explains how Quell Sleep Insights can help you understand the amount and quality of your sleep. The frequently asked questions provide additional information and useful tips. If you are experiencing overnight pain, you may increase Quell use at bedtime and while sleeping. If you have concerns about your sleep, you should discuss them with your doctor.

Frequently asked questions
Sleep monitoring
How does Quell monitor my sleep?
The device has an accelerometer and algorithms that decode your movements and body position, from which sleep quantity, quality, and other characteristics are determined.
How does Quell sleep monitoring compare to other wearable devices?
Most wearable devices are located on the wrist, whereas Quell is placed on the leg. As a result, Quell acquires unique information about body movements and position that provides novel insights about your sleep.
How does Quell know when I got to sleep?
Quell has algorithms that determine when you are in bed and trying to sleep. If you find that Quell is overestimating your Time Asleep, you can indicate when you are about to go to sleep in the “Lights Out” section of the Settings screen.
What can I do if Quell overestimates time in bed?
Reading in bed or watching TV with your legs elevated may be treated as “in bed” by Quell. You can indicate that you are about to go to sleep in the “Lights Out” section of the Settings screen.
Why does Quell occasionally underestimate how much I sleep?
If you tend to move a lot while sleeping, it may be difficult for Quell to reliably determine when you fall asleep. You may disable this feature, called Automatic Sleep Onset, in the “Lights Out” section of the Settings screen. If you do this, you will also need to indicate when you are about to go to sleep.
Why is the amount of time I spend in bed important?
If you have difficulty sleeping and your time in bed is much longer than your Time Asleep, you might consider waiting to get into bed until you are ready for sleep.
How much sleep do I need?

Consistently sleeping less than 7 hours per night is associated with increased pain and poorer health, including weight gain, diabetes, high blood pressure and depression.

What is a typical number of position changes while sleeping?

What does it mean if I frequently change body position?
A high number of Position Changes may indicate that you are uncomfortable while sleeping. One possible cause is pain.
I only change my body position a few times a night; should I be concerned?
There are various reasons for a low number of Position Changes while sleeping. If you have concerns about your sleep, you should discuss them with your doctor.

Why is the app not showing “ON BACK” or “ON SIDE” percentages?
You need to start Sleep Position Tracking in the Settings screen every night you want your sleep position analyzed.
Do I need to start sleep position tracking every night?
Only if you want sleep position information every night.
Does sleep position tracking depend on which leg is the device is placed on?
No, you may place the device on either leg.
Is it better to review my sleep position results over time?
Yes, using the week or month period in the Sleep Tracking screen will provide the most relevant assessment of your sleep position.
Will sleeping on my back increase my snoring?
Back sleeping may increase snoring. Side sleeping is recommended for people who snore or have other sleep related breathing issues. There are a number of recommended ways to decrease back sleeping. Please visit WebMD: 7 Easy Fixes for Snoring.
