Doctors warn of perfumes and scented candles

Allergies and Asthma? Be Careful when Burning Scented Candles

Candles are the most popular mood-makers. In particular, scented candles are very popular. They provide an “individual smell” in shops, at events, in restaurants and in homes. However, lung doctors warn against using scented candles, especially if they are made of paraffin. Paraffin candles are made from petroleum, which is produced from oil. Slags are often used by the oil industry for the manufacturing of candles. This allows the production cost of the candles to be kept to a minimum, ensuring a larger profit margin for manufacturers and retailers. Alternatively, lung doctors recommend candles from beeswax or soy instead, and advise consumers to refrain from scented candles and other scented air products altogether.

Scented Candles – A Problem for Allergy and Asthma Suffers

Pulmonary doctors of the German Lung Foundation (DLS) consider the use of scented candles made from paraffin as a concern for allergy sufferers and asthmatics. When the burning materials are released, they may cause or exacerbate the respiratory symptoms. Even people with perfume allergies are at risk. Skin reactions may be exacerbated by the burning of scented candles. Those with perfume allergies are therefore advised to abandon all scented candles.

Which is of Greater Concern…Natural Fragrance or Chemicals?

It is often stated, it was “only” a natural fragrance. The consumer often makes purchases with this promise of a false sense of security. Whether natural fragrances are a better choice than chemical fragrances is answered by Professor Thomas Fuchs, an allergist with the Department of Dermatology with the University of Medicine at Goettigen, November 2010 in the Rheinische Post: “… in the end fragrances are fragrances, whether they are natural or produced in the laboratory.”

Should those with a fragrance allergy use any fragrances at all? Professor Fox, who belongs to the Association of German Allergists, makes his position on this matter clear: “Those who are affected by a fragrance allergy should also do without all fragrances as much as possible.”

Fragrances Can Trigger Asthma Attacks

Scented candles are very problematic for asthma sufferers. It is reported that some asthmatics must resort more often to using asthma inhalers. Extreme caution must be used to leave locations where scented candles are being burned.

Paraffin Candles Emit Pollutants

“Paraffin candles are made from petroleum,” said Professor Harald Morr, CEO, on the website of the German Lung doctors. “Especially people, who have already developed a contact allergy to certain perfumes, risk the increase from the burning of substances released to the skin or allergic symptoms in the airways. This can cause skin rashes and asthma symptoms.”

Concern for the burning of candles is not just for asthma or allergy sufferers alone, but also for anyone who is in a room where candles are burning. It is recommended by pulmonary doctors from the German Lung Foundation to be cautious and have good ventilation, especially in small rooms or in places with poor ventilation. In addition, they even advise, to set up fans to get rid of the pollutants faster which are released by the candles. Is this advice over the top? Surely not, because especially if several candles are burning at the same time, this can quickly lead to significant pollution in indoor environments. Not only is the paraffin of concern, but also the wicks, which are very often contain lead. The U.S. Environmental Protection Agency published that the proven lead exposure in children was caused to a considerable extent by the burning of candles. (3)

Candle Magic to Create Atmosphere

Those who are concerned about health should refrain from scented candles and instead use candles from plant based sources, soy and beeswax instead of those made from paraffin.

In addition, beeswax candles should be organic. Conventional beeswax is contaminated by pesticides and drug residues which can be expected to be released during burning into the air.

Mood candles in the living room should be limited to special occasions and should be selected for their pollution-free quality. After the use of each candle it is important to thoroughly air out the room, and make sure that candles are “suffocated” completely.

Scientific findings on the causes of contact allergy

Fragrances, which are used in many households and skin care products can cause contact dermatitis when oxygen is exposed to air, as this research shows as presented at the dermatologist conference in Gothenburg, at the University of Gothenburg and at the Sahlgrenska Academy.

The Swedish researchers have focused their research on identifying how these can be activated by contact with oxygen in the air and how this in turn affects the skin. A specially focused study examined whether the activated fragrance caused a contact allergy in eczema patients at the Sahlgrenska University Hospital Dermatology Clinic and at the Occupational and Environmental Medicine Department of Dermatology in Malmö. It was found that a high percentage of the 3,400 patients with eczema had an allergic reaction to the tested fragrance substances.

“In an effort to get a deeper understanding as to how contact allergies occur, we now use state-of-the-art microscopes to track what happens to an allergen when it enters the skin,” said Ann-Therese Karlberg, Professor of Dermatochemistry / skin allergies and researcher at the Sahlgrenska Academy.

When determining how an allergenic substance works, it must be also taken into consideration the skin’s ability to activate a substance by metabolism.

We have developed a mixture that corresponds to the composition of real skin enzymes. We use them to find out if the chemicals can be activated in the skin and to see what the allergen is.”

The discovery from the Swedish scientist will help health service providers by developing new diagnostic tools to correctly diagnose allergic contact eczema, and long-term contribution to reducing the number of cases with allergic contact dermatitis. For the patients, a correct diagnosis that they can avoid exposure to triggering substances, and to heal their eczema gives them a chance.

“Future research will include evaluating new diagnostic methods and conducting more in-depth studies on what penetrates the skin. This will allow us to develop new drugs and to replace the only treatment, cortisone ointment, which is currently available for eczema,“ said Prof. Karl Berg, who believes that their research through their effects on producers, consumers and legislators can improve the prevention work.

Contact allergy

It is estimated that in Europe almost 20% of the population is affected by a contact allergy, which means that patients develop eczema when they come into contact with substances to which they are allergic. After nickel, fragrances are the most common cause of contact allergy. For this type of allergy, there is no cure, but cortisone cream can alleviate the symptoms, and avoiding all possible contact with the allergen is helpful as well.
