The makers of Spire  believe fitness is comprised of both mind and body and that being healthy is about more than exercising and eating well. True health, according to those at Spire, means having clarity, control, and inner peace.
What is Spire?
Spire is a wearable device (it clips onto your pants or bra) that offers the same movement features as other activity trackers on the market but with the addition of sensors that monitor how you react to stress. Our bodies are constantly giving physical cues that indicate our mental state, such as increased or shallow breathing, rapid heart rate, and perspiration. Spire picks up on these cues and alerts you in real time so that you can adjust your behavior and reduce the effects of stress.
For example, if you are in a meeting with your boss and things are not going well, you might feel a little vibration from your Spire. A notification on your phone (which synchs to Spire) will indicate that your heart rate is increasing and that you need to breathe deeply. It sounds almost too simple, but researchers say correcting the physical effects of stress allows us to better tackle the mental effects, even in the heat of the moment.
And this goes for situations that you don’t even know are stressful, like driving on highways or talking with certain people. The creators of Spire hope that by becoming aware of how our bodies are reacting at any given moment, we can create a positive feedback loop and get relief from stress. Breathing is literally the only automatic function in our bodies that we also have control over. How you breathe sets up how you feel, and vice versa.
How does it relieve stress?
The main way that Spire works, like other fitness wearables, is by tracking and accumulating information that we are too busy or unable to track ourselves. Sensors detect your breathing and respiratory movement, including the depth of each individual breath. Advanced algorithms allow the device to make sense of your breathing patterns based on multiple laboratory studies that show links between respiration patterns and emotional states. In addition, Spire is customizable and able to tweak and reinterpret the data it receives over time (“stressed” for you is different than “stressed” for someone else).
Because Spire is always tuned in to your behavior, it also serves as a monitor during times of calm and focus. Looking at your data and recalling moments of peace, contentment, and clarity can allow you to reproduce these results at a later time.
How much is it?
I was very surprised to see that Spire costs just $99, considerably less than many other wearable fitness trackers. Considering the fact that Spire still tracks steps and calories expended in addition to the other respiration tracking capabilities, it seems that people in the market for this type of device might benefit from having a look at Spire. It may not be an overnight cure-all for stress, but those interested in “body hacking” may find it’s a welcome tool for providing a more complete picture of the whole self.
