Visual: Sunlight, though I can generally minimize this by staying indoors. Flickering lights, particularly red or yellow lights. The color red.
Auditory: Low-pitched, loud noises, or high-pitched loud noises. Examples include airplanes, blenders, carpet cleaning trucks, smoke alarms, fire alarms, sirens, and children screaming or crying. Much harder to avoid these, though I have good noise-reduction headphones to help.
Tactile: Touch from an unfamiliar person, or an unexpected touch from a familiar person. Any fabric that is not very soft. I only wear loose cotton clothing, with all labels removed. Buying socks is particularly challenging. If my feet didn't get so cold, I wouldn't wear them. I cannot wear turtlenecks, shifts that button all the way to the neck, watches, rings, or anything other jewelry, or belts.
I also have sensory integration issues. For instance, the McGurk effect does not work on me. So any complex sensory environment will likely tire me out.
