Cooking and cleaning are two of the main sources of indoor pollution. Indoor air quality can be affected by cooking and cleaning, as per researchers of Colorado State University. The results of the study were published in the journal, ‘Environmental Science & Technology’. Cooking generates unhealthy air pollutants from heating oil, and other food ingredients, especially at high temperatures. Self-cleaning ovens can also create high levels of pollutants as food waste is burned away. Exposure to these can cause a wide range of health problems such as headaches, fatigue, and nausea. Young children and people with asthma or heart disease are especially vulnerable to indoor air pollution.
