Overusing the heater or using an oversized heater can result in elevated levels of carbon monoxide or nitrogen dioxide fumes in the air. These fumes can cause cold or flu-like symptoms, headaches, and eye, nose and throat irritation. Don't use these heaters as your main heat source, even during power failures.
Some forms of electric heating can cause dry air, which could trigger asthma symptoms. Inadequate ventilation in spaces heated by electric heaters could lead to a build-up of indoor air pollutants such as dust and pet dander.
For most people, Lizarzaburu says that, for most people, heater illness symptoms shouldn't last more than a few days.
Vented and Unvented Combustion Small Space Heaters
They may also bring unwanted nitrogen oxide into the home; nitrogen oxide can cause asthma and other respiratory problems. These heaters can also introduce water vapor into the home, which can result in mold and other structural damage.
Key points about carbon monoxide poisoning
A common source is unvented space heaters. Symptoms of CO poisoning include headache, dizziness, weakness, nausea and vomiting, rapid heartbeat, shortness of breath, seizures, chest pain, disorientation, and loss of consciousness.
Since CO has no odor, color or taste, it cannot be detected by our senses. This means that dangerous concentrations of the gas can build up indoors and humans have no way to detect the problem until they become ill.
Similarly, closing our windows and using heat can increase your exposure to lung irritants, such as dust and allergens. This can cause itchy and watery eyes, coughing, headaches, sneezing, and more.
Space heaters can significantly dry out the air in a home, leading to various respiratory issues. Dry air can cause irritation of the respiratory tract, leading to symptoms such as coughing, sore throat, and dry nasal passages. It can also exacerbate existing conditions like asthma and allergies.
Sleeping with the heater on increases the levels of carbon monoxide in the room. People with heart disease may get chest pain, while smokers with heart disease are particularly at risk, so are young children and elderly. The risk of asphyxia (sleep death) is high when using gas heaters.
While they effectively raise the temperature, they also tend to overheat the space. It means that warm, dehumidified air can dry out your nasal passages, creating it uncomfortable to breathe and potentially causing health issues.
Don't leave the heater unattended for long
Always remember to switch off and unplug the appliance before leaving the room or going to bed. Prolonged usage of heaters in closed rooms can be dangerous as it can create carbon monoxide poisoning which can cause headache, dizziness, nausea and weakness.
Overusing the heater or using an oversized heater can result in elevated levels of carbon monoxide or nitrogen dioxide fumes in the air. These fumes can cause cold or flu-like symptoms, headaches, and eye, nose and throat irritation.
According to the CDC, carbon monoxide is a silent killer that takes hundreds of lives per year. Unfortunately, you cannot tell just by looking at your furnace whether it is leaking carbon monoxide. You need a carbon monoxide detector or other special equipment to test the levels yourself.
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.
While in use, heaters lower humidity levels in your home and force hot air through dusty, dirty vents, filters and ducts, if poorly maintained. Constantly breathing extremely warm, dry air that may contain fungi, mold and mildew from the vents can affect your skin, nose, throat and eyes.
It's important to note that an indoor temperature of less than 16°C increases the risk of asthma and other respiratory conditions while going below 12°C puts the cardiovascular system under stress. A cold home can also increase your risk of depression and confusion.
While electric space heaters do not produce carbon monoxide (CO), non-electric space heaters (propane gas, natural gas, kerosene, wood) can if incomplete combustion occurs. If these types of heaters are in use, it is recommended that a working CO detector be used to indicate the presence of high-level CO gas.
Other factors that make a person susceptible to heat illness include older age, heart disease, other chronic diseases, extreme exercise, sunburn, obesity, sleep deprivation, alcoholism and certain medications.
General Symptoms:
Heavy sweating. Painful muscle cramps. Extreme weakness and/or fatigue.
Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.
The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO, it can make you pass out or kill you.
