Ozone (O3) is a naturally occurring gas that can be beneficial at high levels in the upper atmosphere, where it acts as a protective shield against harmful ultraviolet (UV) radiation from the sun.
However, at ground level, ozone can be harmful to human health.
Breathing in ozone can irritate the lungs and airways, leading to a range of symptoms such as cough, chest pain, shortness of breath, and worsening of asthma and other respiratory conditions. It can also irritate the eyes, nose, and throat, and can cause chest tightness and wheezing.
