Can Candles Cause Carbon Monoxide Poisoning? (And How To Protect Yourself)

Candle burning is a popular pastime. It’s romantic, relaxing, and reduces stress. But what if burning a candle could be harmful to your health? What if it could even kill you? Well, there is no such thing as a “safe” candle burning.

However, unless you’re using something like beeswax candles or soy candles (which produce far less harmful smoke than paraffin-based ones), chances are very slim that you’ll poison yourself with carbon monoxide created by your favorite scented wax stick.

What is carbon monoxide?

Carbon monoxide is a colorless, odorless gas. It is toxic to humans and animals. Carbon monoxide is produced during the incomplete combustion of carbon-based fuels such as gasoline, diesel fuel, charcoal, and wood. Some natural gas contains small amounts of carbon monoxide as well.

Carbon monoxide can build up in enclosed areas as a result of vehicle exhaust or appliances burning solid fuels such as coal or wood. In homes, carbon monoxide may come from an exhaust pipe or flue that does not have enough airflow to remove it from the room.

Indoor sources include cars, trucks, and buses; furnaces; space heaters; water heaters; stoves; fireplaces; gas ranges; gas dryers (or clothes dryers); gas ovens; fuel-burning appliances (such as water heaters and furnaces); propane tanks (including portable tanks used by campers).

Carbon monoxide is also present in buildings where it was used as a refrigerant or in heat pumps where it was used as a cooling agent.

What is carbon monoxide poisoning?

Carbon monoxide poisoning is a type of poisoning that occurs when carbon monoxide, a colorless, odorless gas, combines with hemoglobin in the blood. Carbon monoxide is a byproduct of incomplete combustion caused by burning fuel without purging the air of exhaust before it is burned. It can also be produced by generators and other manmade sources.

Carbon monoxide poisoning can have serious consequences, but symptoms may not appear until hours after exposure to the gas has ceased. Early symptoms include dizziness, headache, nausea, and vomiting. In severe cases, victims may experience shortness of breath or chest pain or become unconscious before they realize they are poisoned.

If you suspect you have been exposed to carbon monoxide, seek medical help immediately and call 911 if you have any symptoms of poisoning or exposure to the gas.

How to tell the difference between carbon monoxide poisoning and flu?

You can tell the difference between carbon monoxide poisoning and flu by the symptoms.

Carbon monoxide poisoning is caused by breathing in too much carbon monoxide gas. The symptoms are headaches, nausea, and dizziness. If you suspect that you have been exposed to carbon monoxide, call 911 or go to the emergency room right away.

Flu is caused by a virus that causes your body to make too many antibodies at once. The symptoms of flu include fever, chills, and muscle aches. If you suspect that you have been exposed to the flu, call your doctor as soon as possible.

Do candles produce carbon monoxide?

Unlike the other chemicals discussed in this article, candles produce a large amount of carbon dioxide and water vapor. The amount is small enough that it’s not considered dangerous by most people, but if you’re concerned about your safety or the safety of your home, you might want to avoid burning candles altogether.

How many candles are needed for carbon monoxide poisoning?

The number varies depending on how long you burn each candle and where they’re being used (e.g., inside versus outside). If two identical mason jars were filled with equal amounts of soy wax pellets and paraffin wax pellets, one jar would last longer than the other because there’s more surface area on which heat can be emitted from both containers—and thus more potential for combustion reactions inside those containers!

Most candles are made from paraffin, a petroleum by-product, or beeswax, but soy and tallow (animal fat) candles can also be found.

Paraffin, beeswax, and paraffin wax are all by-products of petroleum. Soy wax is derived from soybeans and tallow (animal fat) candles are made from beef tallow. Scented candles are often made with either paraffin or soy wax.

Candles are sold in different shapes and sizes depending on their function: votive holders for smaller candles; tea lights for larger ones; pillars or candelabras for groups of large strings that can be used throughout your home space without losing their scent through heat.[1]

Candles do not produce carbon monoxide gas.

Long ago, we learned that candles produce carbon monoxide. This is true and it’s not a myth. But let’s take a moment to look at what happens when you burn a candle.

Carbon monoxide is an odorless gas that is produced by incomplete combustion of organic materials in the air (you know, like any fire), and it interferes with your body’s ability to use oxygen from the air around you.

When this happens, your body struggles to get enough oxygen into its tissues for proper function and repair. The symptoms of carbon monoxide poisoning include headache, nausea/vomiting, or dizziness/shortness of breath—all signs that something isn’t right inside your body!

Is it safe to burn a candle in a closed room?

If you’re burning candles in a closed room, you’re probably wondering whether it’s safe. The answer is simple: yes! It is safe to burn candles in your home or office. There are many benefits to using candles, especially if you love the smell of them burning. You can find many different scents offered by many companies today, and they all come with their unique smell.

There are some negative effects of burning candles in your home or office, but those are minimal compared to the positive ones that come with using them. For example, if you live next to a neighbor who doesn’t like the smell of your candles burning, then that might cause issues for you.

But even if this does happen, there are ways around it like placing some type of fragrance diffuser next to your candle allowing its fragrance to reach outside of your home into theirs. This will help reduce any negative feelings from your neighbor about having a strong scent wafting through their home and yours as well.

Be sure to be safe with a carbon monoxide detector.

The American National Standards Institute (ANSI) has set the following recommended CO alarm minimum sound thresholds:

CO alarms should sound for at least 30 seconds when set to low or medium sensitivity levels for a single smoke detector operating with either battery backup or power failure protection. For CO alarms with power failure protection, the time must be no less than 10 seconds and no more than 90 seconds.

When installed in a new home according to the manufacturer’s instructions, carbon monoxide detectors must be tested within 24 hours of installation and provide an audible signal for at least 30 continuous seconds when tested by an ANSI-certified tester. If a CO detector fails this test, it must be replaced or repaired immediately by a qualified person.

Burning a candle to its end could result in soot production and/or smoke residue that may pose health risks.

As you know, burning a candle to its end can result in soot production and/or smoke residue that may pose health risks. Soot is not good for your lungs and can cause cancer. It can also cause respiratory problems in children and infants, as well as cataracts.

If you’re concerned about the health effects of soot production during candle-burning sessions, consider investing in an electric warmer instead of putting out the flame yourself!

Exposure to high levels of carbon monoxide during pregnancy may cause spontaneous abortion or early delivery.

As you didn’t know, carbon monoxide exposure during pregnancy can cause spontaneous abortion or early delivery. The effects of carbon monoxide on an unborn fetus are particularly dangerous because the placenta can absorb a lot of the gas. It’s also possible for infants born with high levels of CO in their blood to suffer from birth defects like heart problems and lung malformations (e.g., pectus excavatum).

In addition to these risks for mothers and fetuses alike, there have been reports of children who have died from inhaling too much CO through cribs or stoves — so even if you haven’t had any symptoms yourself, keep an eye out for any signs that your child might be struggling with this issue!

People with chronic heart disease and those who suffer from chronic lung disease may experience more severe symptoms if exposed to carbon monoxide. Symptoms of carbon monoxide poisoning include headache, nausea, vomiting, dizziness, shortness of breath, fatigue, and loss of consciousness.


Even though candles don’t produce carbon monoxide, burning one can cause you to inhale soot. This could potentially lead to health problems in the form of respiratory issues such as chronic bronchitis or emphysema. The best way to avoid this is by making sure that your candle is clean before lighting it up.
