No, ozone is not safe for humans. While ozone in the stratosphere protects us from harmful UV radiation, ground-level ozone is a harmful air pollutant.
Ozone's Harmful Effects on Human Health
Inhaling ozone, whether in its pure form or mixed with other chemicals, can be significantly detrimental to human health. The negative impacts are well-documented by various health organizations and government agencies.
- Respiratory Problems: Ozone irritates the respiratory system, leading to coughing, shortness of breath, throat irritation, chest pain, and tightness. [Source: EPA, California Air Resources Board, American Lung Association, U.S. National Park Service]
- Lung Damage: Exposure to ozone can cause damage to the lungs. Even relatively low amounts can have adverse effects. [Source: EPA, various health agencies]
- Premature Death: In combination with other risk factors, ozone exposure can contribute to premature death. [Source: American Lung Association]
- Ineffective Air Cleaner: Ozone generators, often marketed as air cleaners, are not only ineffective but also pose serious health risks due to the ozone they produce. These devices may also create other dangerous chemicals. [Source: EPA, California Air Resources Board, Health.ny.gov, Canada.ca]
It's crucial to remember that the ozone layer in the stratosphere is beneficial, but ground-level ozone is a completely different and harmful substance. Ozone therapy, despite some claims, lacks sufficient evidence of safety and efficacy for medical use. [Source: Medical News Today]
