I’m not sure if it would. I have given multiple of Sapien’s fields to people who don’t really pay attention to “Spirituality” or any form of spiritual practice, and their able to mix them just fine. Personally, I believe it depends on what fields your mixing and what kind of effect all of them would cause on you. If your listening to alot of physical oriented fields, its natural you may get tired and your bodys gonna use up more energy to compensate. Especially the workout ones, I’ve always eaten 2-3x more than normal if I used them lol.
The same goes for mental ones, I’ve noticed people get more used to them, but they have to pace themselves properly. Also just like the physical ones burning more calories, the mental/“brain” ones can have a similar effect.
Short Version:Pace yourself and your threshold should increase as long as you take the proper steps to go with it (Eat nice, Sleep Properly, Don’t Overdo things if you ever start to feel uncomfortable)
