The sun is out today here in Surry, New Hampshire and I managed to drag my self out for a snowshoe in the woods. I soaked up the broad spectrum beams and felt much better upon my return home (see my video below). Exercise is key to fighting dysphoria across diagnostic groups...meaning that people with all sorts of Axis One or Two disorders may also have co-occuring Seasonal Affective issues which are often neglected.
It's often difficult to get people with Autism and related problems out to exercise when it's cold due to their inability to endure even low levels of discomfort. And we know that exercise (whether for individuals with ASD's or no disorders) is a matter of conflicting consequences: Short term discomfort for long-term benefit. But alas, neurotypicals and people with ASD's alike need to "get out" and get those endorphins moving and people with ASD's may need a bit more of a push.
