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.
