Chalky foods (merengues, smartie candies, antacids, etc). I also hate the sound of chalk being used. It makes my teeth hurt.
Blue LEDs that aren’t properly balanced (they give me migraines)
Electricity whining (I can hear this almost anywhere inside)
Dense fleeces (they make me itchy regardless of material)
Turtlenecks (I feel like I am choking)
If you are like me and looking for nice holiday lights that won’t hurt your eyes, check out Technology Connections on YouTube who has tested all the brands and found two that include soft blue lights! I am investing in them soon because I miss having colored lights.
