Here is a list of things to avoid while staring at the hand.
It is imperative that you do it far enough away from all manmade radiation, (note that we didnt evollve near such radiation) , like within ten or fifteen feet of a computer or monitor.,flat screened or large screened tvs,, regular tv's if super close, , cordless or cell phone even carrying them in your pocket when not turned on due to the battery, radio, some modern cars which are now full of computer chips, and car radios etc, the street power line shouldnt be within ten or ffifteen yards of you. No giant transmission towers should be in your vicinity.This manmade radiation, if we are too close to the source makes the immune systom not able to be stiumulated.
. Take your watch and rings off. too. I can explain how that reduces the effectiveness to be wearing either. Nothing should be in your ear like a hearing aid and smoking is another big category you must avoid as it too reduces the effect greatly.
Immunosuppressive drugs too will reduce the effect , like the synthetic opiate pain killers, sleeping pills like ambien, antianxiety meds like valium, poppy seeds since they contain traces of opium, marijuana , alchohol, nicotene, muscle relaxants, cough meds, menthol
