All the time -
Sound - I have huge issues with sound /misophonia to the point that I wear earphones or earplugs most of the time. But my hearing is so acute that I can often hear through them (really must get noise cancelling headphones, but damn they're expensive). Any loud noises, shrill / high pitch noises, sudden noises, whispering, constant din such as fridges cooling / fish tank filters etc, mouth noises primarily slurping, sucking, chewing, anything involving spit noises, anything with the mouth that is not speaking I can't stand it.
I once read an article on misophonia somewhere that theorized that the sound information is rerouted via an auditory processing disorder through the fight / flight areas of the brain, and that is how I respond to most sound. Even if I know intellectually it is benign, it is still perceived as a threat, and reacted to via an involuntary instinct. Like snatching your hand off a burning hotplate. You can't control this.
Touch - being touched and the threat of being touched, especially by people who I have told not to touch me and that I don't like to be touched, and they continue to do so. I also can't stand anything restrictive on my body, such as tight clothing or smothering like blankets that exert pressure on my skin.
Heat - can get overwhelmed by uncontrolled heat, including that generated by my own body when exercising. Can only do so in very cool spaces / not wearing much so my body can be kept cool enough. Can't regulate heat properly.
Light - bright light, fluro light, halogen light, dramatic contrasts between light (re pricks in oncoming traffic who refuse to turn down their highbeams on dark nights).
At the moment - other people. I just can't deal with other people at the moment and their very presence is too much.
