I use the method of keeping my senses calm to help my moods.
When I am more prone to react to my surroundings - over stimulization of some senses pushes me over the edge quicker, and if I can keep my environment stable, I can sometimes avoid over-reactive responses.
Examples, low lighting, using sound on low - or noiseless. Shutting away to keep surroundings calm. Using light scents.
My spouse is a quiet person, we both use headphones, and our dogs don't bark - maintaining sounds (and for him lighting must be low) help us both immensely.
Does anyone else use this method - or would like to try it and share.
