The emWave2 is meant to be used for "training" yourself to develop self-control. Because of this control we can improve mental performance. Most of the sessions I have published involve tasks of simple concentration, slight distractions through visual/audio, and writing. This new session involves playing a video game.
The image above and and the HRV charts below are the result of playing Ghost Recon Online, without putting a major emphasis in self-control. This is what my body does when it plays video games.
The results point heart rate of 80. Coherence of low (67%), med (19%), and high (14%), were recorded. These results compared to previous sessions demonstrate a degrading of "good" scores. In a way gaming is causing some stress. During the 20 minutes of gameplay I only managed to get 21 seconds of continuous high coherence. What's even more surprising is that I did poorly during the game (placed on the bottom scores of the squad). The next session shows the results while controlling my breathing.
Coherence levels compared. The first number is what would be the "normal" scores, the second is what I achieved trying to control my breathing when playing the video game.
The HRV chart above show periods of intense activity, and then periods of "rest." When my digital-self found itself confronting a dire situation the heart increased activity, but it was easier to bring down the rate when the situation intensity decreased.
While the emWave2 is intended to be used in a "training" way, I don't think the function should be exclusive to only that task. To me, everyday tasks are more important than simply "meditating." Exercising self-control in normal everyday activities are the "real improvements" I'm seeking. By having the emWave2 I can now track most things by using the ear sensor.
I learned the importance of self-control while being in the Marines. For distance runs it is better to have a steady pace than run variably with sprints and slow downs. The oxygen provided by the lungs have an effect in the entirety of the body (heart, muscles, brain, etc).
While these days I do more "desk jobs" than the "very physical" tasks I can see that reminding myself of taking good deep breaths will improve performance. But in case I forget to practice self-control, the emWave2 is a good method of establishing the habit.
