For many sufferers, the smell of cigarette smoke, heavy perfume, or cleaning chemicals acts as an instant trigger. This is due to a hyper-connected olfactory system that bypasses typical sensory filtering and sends an immediate "threat" signal to the brain's pain centers.
If certain scents trigger you, your nervous system is likely already near its threshold. Identifying these scent triggers in your logs helps create a safer environment and shows your doctor the full picture of your sensory sensitivity.
The Relief app correlates your attacks with weather, sleep, food, and more — automatically.
