High energy and short wavelength of blue (around 450nm) fits argon.  Not common to work with, but light therapy in general can be associated with trendy terms and claims.  See how it continues to work for you.

Hi,

There's no insinuation you claimed anything, you inquired if it was coincidental.  Light therapy in general was mentioned to be associated with claims that could be considered trendy.  If wondering about being coincidental, further experience was mentioned simply as an opinion.

Understandable, no problem.  You're kinda new here, I can be a round-about, general idea communicator, mostly due to abbreviated and and sloppy notetaking type writing.  The dictionary's a damn three steps away, it's got dust on it.   Only sometimes even I know what I'm talking about.   

If we accept that episodic CH is at least partially associated with circadian and/or circannual cycles, light therapy seems like a reasonable additional preventative.  It can't hurt anything (except for the pocketbook if you get one of those fancy full-spectrum light units sold for Seasonal Affective Disorder.)  You can get full-spectrum light bulbs at Home Depot.  Sit in front of bright lights in the early morning and evening see if it helps.

That being said, my cycles tend to start right after the spring equinox, when days start to get longer here in the northern hemisphere.  I think that, at least in part, I absolutely love Autumn -- the days get shorter!  Everyone's cycles fall their own rhythms, though.

I believe I have SAD (seasonal affective disorder). Never been formally diagnosed but I can deeply feel the change in light and its impact on my overall mood. I have tried light therapy for mood and it does seem to have a positive effect. But its the type of thing you have to stick with for it to really work.

Have no idea of its potential for CH.
