We recommend you do it daily so you are well-regulated every day. When you get triggered or stressed, it's when you use it.  It's like an anchor that's always there to keep you calm and cool. There’s a saying that strikes the iron when it's hot. The best time to practice breathwork or nervous system techniques is when you are calm and relaxed. So that you remember how to breathe slowly and steadily. It will be harder when you are triggered or stressed. Practice it regularly so that when you are being triggered or stressed, you can pick up easily. We recommend you do it 10 times for each practice.  Imagine when you are going into an important meeting and you were triggered with anxiety, you could feel the weight of the necklace, as you touched it,  it reminded you to breathe deeply and focus on the air in and out which prevented you from spiraling down negative thoughts.
