Hello Jessi,

There are two types of fatigue.[/B] There’s the type of fatigue that comes from doing more than one has the fuel for. Like the tired one gets from climbing a mountain. This is basically doing more than one has the fuel for or doing more than one CAN have the fuel for.
The second sort of fatigue comes from leaky kidney energy. This would be something to watch in your own practice and it is a requisite action in backbends but it is not an action limited to backbends. Additionally there are restorative practices as I;m sure your teacher training imparted. Such practices can focus on or target the aforementioned kidney energy.

Share from your overflow not from your self[/B]. Put another way a teacher of yoga is trained to champion their own energy, protect it, and not over give when teaching. There are two pragmatic ways to do this, The first is through Yama and Niyama, specifically Saucha. Why? Because the energies we pick up are not our and they need to be lifted or removed from our layers or Koshas.
I suggest clean clothes each time you teach and bathing immediately after. When that is not possible at very least wash your hands and feet right after class - as in before leaving the studio. Certainly effort to NOT bring the teaching gook home. We all have stuff and the teacher who does not learn to protect themselves will assuredly pick up things from students.
[B]Active meditation[/B]. Unfortunately most Hatha yoga systems forsake meditation or cling to an antiquated position relative to its practice and use. Here the work is to connect with the heart center, bring light into it, then spread that light around the physical form thus creating an energetic cocoon of light. This can be done while you are teaching Savasana just before you bring students up and out for your closing.
Additionally I would avoid wearing of dark colors as they suck up available “light” and do not reflect the effulgence of Yoga. They hide things and there is no room for more hiding in yoga as we are already doing enough hiding in the world.
[B]Nutritional aspects[/B]
Please avoid caffeine, alcohol, tobacco, and refined sugar.
As far as supplements are concerned I prefer food-grade herbs when I can vet the company, formulations, and production before turning my money over (basically supporting or voting for whatever said company is doing). That having been said, I’ve found Sunrise from the Sunrider line to be most effective with supporting my energetic needs. It is not the only thing I take but a good start. If you want more information feel free to PM me.
