i have two strategies for soothing which smooths-over the rough edged rasp of life:
avoidance- i am a hermit, and in my semi-controlled private environment, i control how much of anything i have to experience;
amelioration- i wear sunglasses outdoors, year-round, for as long as the sun is shining. i wear noise-suppressing earmuffs when outdoors doing yard work, and when i am walking outdoors, i plug my ears whenever something noisy cruises by me. i wear minimal clothing, and it is loose-fitting to a fault. air-conditioning in the hot summer months is a must. i block out the sounds of my noisy neighbors with my own soothing noises, either with music or a loud large box fan which produces a masking dull roar.
