Heaters may be essential to keeping warm during the cold winter months, but they can also pose a serious health risk, causing respiratory diseases by depriving people of oxygen. Improperly installed appliances may not burn fuel properly, leading to emission of poisonous gases such as carbon monoxide.
According to the World Health Organization, gas stoves, smoke hoods, and heaters increase indoor air pollution and health risks. Indoor air pollution due to solid fuels increases the risk of pneumonia among children and chronic respiratory diseases among adults.
