When Goosebumps Are Normal—And When They’re Not
Goosebumps are usually harmless, triggered by cold or strong emotions like fear or awe.

They occur when tiny muscles at the base of hair follicles contract, making hairs stand up—a response tied to the body’s adrenaline-fueled “fight or flight” system.

Normal Triggers Include:
Cold temperatures
Emotional reactions (music, memories, fear)
Watching thrillers or horror films
goosebumps appear without clear reason, it might signal an underlying issue:

Nervous System Disorders – Conditions like epilepsy or MS may disrupt nerve function, causing random goosebumps.
Seizures – Rare “piloerection seizures” may cause goosebumps, especially with other symptoms like confusion or blackouts.
Hormonal Imbalance – Tumors like pheochromocytoma can trigger adrenaline surges, leading to spontaneous goosebumps.
