Aloha Orca71,
Ideally you'd want to give the body 15-20 minutes to settle after doing the active exercises and or meditation, but if you need to go, you need to go.
One thing My wife does with the Spring Forest Meditation groups in the winter is make sure they do the harvesting at the end of the work (generally they do an hour of active and an hour of sitting meditation), and then spend a couple minutes cupping C7 before going out side (with their neck and back of the head amply protected.
Much Love,
Shawn
