A man from North Wales has a strange reaction to the smell of his wife’s perfume: A simple whiff of Chanel No. 5 can make him collapse, according to The Daily Express.  

Glynn Parry, 36, suffers from familial hemiplegic migraines, a rare genetic condition that causes certain channels of the brain to temporarily stop working.  This ultimately leads to weakness – and even paralysis – on one side of the body.

According to Parry, his migraines are mostly triggered by strong odors.

“Some people react to chocolate, cheese, alcohol and caffeine. I’ve cut all of these out just to be safe,” Parry told The Daily Express. “But one of my strangest and strongest triggers is smells. I’m very sensitive to them. My wife Carrie wore some Chanel No 5 and I just dropped.”

Parry’s wife, Carrie, told the paper that she has stopped using the perfume and only uses mild shampoos in an effort to protect her husband.

“The worry is this could be life-threatening or he might not quite recover from an attack,” she said.
