Definition
Noun: - An illness that can affect people exposed to high concentrations of ozone, typically encountered in the cabin air of high-altitude aircraft. Symptoms include drowsiness, headache, chest pain, and itchiness.
Usage
This is a specific medical condition related to a particular environmental exposure. It is used in medical, aviation, and occupational health contexts. - Early jet aircraft sometimes had poor filtration, leading to occasional cases of ozone sickness among passengers and crew. - The symptoms of ozone sickness can resemble those of mild hypoxia or other ailments.
Advanced Usage
