☕️Ever walk into a busy café and feel like the espresso machine, fluorescent lights, and small-talk chatter are all shouting directly at your brain?
That hyper-awareness isn’t you “being dramatic”—it’s often your thalamus (the brain’s sensory traffic cop) waving a frantic red flag.
What’s happening behind the overwhelm
📣Microglial megaphone — When low-grade inflammation sneaks past the blood-brain barrier, microglia release cytokines that dial up the volume on every incoming signal. Suddenly a normal clink of silverware lands like a cymbal crash.
🚨Thalamic filter fail — Cytokines jam the neural circuits that usually sift background noise from must-know data. Picture your spam filter quitting mid-workday; every ping hits your primary inbox.
➡︎Neurotransmitter tug-of-war — Inflammation drains dopamine and GABA, the very chemicals that help you stay calm and focused, leaving your sensory gates wide open and unguarded.
Everyday red flags
🚩Grocery aisles feel too bright or echo-y.
🚩You keep turning car radio volume down—even on your favorite song.
🚩Scratchy clothing tags or perfume that never bothered you now feel unbearable.
🔑Key Takeaway:
If sensory overload tracks with blood-sugar dips, post-viral slumps, or moldy rooms, you’re probably looking at a neuroinflammatory flare—not personality quirks. Start with: stable protein-rich meals, a two-minute nasal-breathing reset in noisy spaces, and evening blue-light limits. Cool the cytokine cascade, and the world turns down from “stadium concert” to “soft jazz” again.
