4 million people a year die from indoor cooking smoke

What’s causing the air inside people’s homes to be so poisonous that it can kill around 11,000 people a day? - Stoves and Gas ovens without a chimney in the kitchen. “Having an open fire in your kitchen is like burning 400 cigarettes an hour,” says Kirk Smith, a professor at the University of California at Berkeley, whose research suggests that household air pollution from cooking killed between 3.5 million and 4 million people prematurely in 2010. These are caused by the cooking heat from burning the solid fuels or gas ovens. The lousy ventilation then prevents that smoke from escaping, sending fine particle levels soaring 100 times higher than the limits that the WHO considers acceptable.

Indoor air pollution may be as much or more of a problem as pollution outdoors, according to new research

"When we think of the term 'air pollution,' we tend to think of car exhausts or factory fumes expelling gray smoke," said study co-author Prashant Kumar of the University of Surrey. "However, there are actually various sources of pollution that have a negative effect on air quality, many of which are found in our homes and offices. From cooking residue to paints, varnishes, and fungal spores, the air we breathe indoors is often more polluted than that outside. Those who live in cities spend up to 90 percent of their time indoors — most of the air they are breathing is "indoor air." Sometimes that air is similar to outdoor air, especially in well-ventilated buildings. But additional pollutants are killing significant numbers of people worldwide. For example, the World Health Organization has said that household cooking with coal or biomass-burning stoves led to 4.3 million deaths in 2012, compared with 3.7 million deaths from outdoor air pollution.

Indoor cooking fire is equivalent to 400 burning cigarettes

Kirk Smith, a professor at the University of California at Berkeley, describes having an indoor cooking fire as being equivalent to burning 400 cigarettes an hour. Breathing the smoke infused indoor air day in and day out eventually causes a slew of diseases: more than a third of the 4.3 million who die prematurely each year succumb to a stroke, while a quarter die of ischaemic heart disease. And around one-third of annual lung disease deaths worldwide are due to exhaust from coal- or biomass-burning stoves, which is way more than deaths out of cigarette smoking.

Indoor Air pollution 10-30 times than outdoor pollution

Most people spend 85% of their life indoors — inside homes or offices, commercial or industrial buildings or schools and colleges. With the increasing incidence of respiratory illnesses in the country, health experts warn about the indoor air pollution hazards as several studies show that indoor pollutants are much higher than those in an urban outdoor environment.  According to Dr. Vivek Nangia, director of pulmonology, Fortis Flt Lt Rajan Dhall Hospital, New Delhi, “Air pollution is an invisible killer.” In some homes, the indoor air pollution has been found to be 10-30 times that of outdoor pollution, Nangia said.
