Fragrance And Asthma: A Triggering Scent?

Fragrances and strong odors have been identified as possible triggers for asthma symptoms. Many asthmatics avoid fragrances and strong odors, and 41% of people with asthma report health problems from air fresheners or deodorizers. While the mechanism by which exposure to pure, non-irritating odorants can cause an adverse reaction in asthmatic patients is still unclear, it is believed that physiological and psychological processes are involved. For example, the perception of an odor as harmful can lead to cognitive and emotional responses that affect biological pathways and cause changes in smooth muscle tone, airway inflammation, and increased airway sensitivity to inhaled agents.

Perfumes, in particular, are common triggers for asthmatics. They often contain chemicals derived from coal tar and petrol, which help the fragrance stick to the object it is sprayed on. Other fragrance sources that can trigger asthma include colognes, nail polish and remover, wood-burning stoves, carpet and flooring materials, paint and paint thinner, bathroom sprays, and air fresheners.

To manage asthma symptoms triggered by fragrances, it is recommended to avoid known triggers, take regular preventer medication, and inform friends, colleagues, and employers about fragrance use to reduce exposure.

Fragrances and strong odors can exacerbate asthma symptoms

Perfumes are often made with chemicals derived from coal tar and petrol, which help them stick to the object they are sprayed on. Other agents used in perfumes include petrochemicals, alcohols, and coal, which can all be harmful to asthmatics.

In addition to perfumes, other common sources of strong odors that can trigger asthma symptoms include colognes, nail polish and remover, wood-burning stoves and fireplaces, carpet and flooring materials, paint and paint thinner, bathroom sprays, and air fresheners. These products often contain chemicals with strong odors that can irritate the airways of asthma sufferers.

It is important for individuals with asthma to identify their specific triggers and take steps to avoid them. This may involve using fragrance-free products, improving ventilation, and asking others to limit their use of strong fragrances. Taking regular preventer medication, as prescribed by a doctor, can also help reduce inflammation in the airways and lower the risk of an asthma attack.

While the exact mechanisms behind how fragrances and strong odors exacerbate asthma symptoms are not fully understood, it is clear that they can have a significant impact on individuals with asthma. Avoiding these triggers and managing asthma symptoms through medication and lifestyle changes are crucial for preventing asthma attacks and improving quality of life.

Asthmatics can avoid fragrances and strong odors by using fragrance-free products

To avoid triggering asthma symptoms, asthmatics can use cleaning and personal care products that are odor and fragrance-free. For example, rose water, which is made with just water, rose essential oils, and sometimes a mint aroma, has been noted as a fragrance that does not trigger asthma symptoms. Asthmatics can also ask friends and family to limit their use of perfumes and make sure their home and workplace are well-ventilated.

In addition to using fragrance-free products, asthmatics can also benefit from using air purifiers with HEPA filters and activated carbon to absorb chemicals from the air. When going out in public, asthmatics can carry a respirator to avoid problems when passing by strong odors or fragrances. Some public spaces, such as hospitals and doctors' offices, have started to implement fragrance-free policies to support those with asthma and allergies.

Asthmatics can ask friends and family to limit their use of perfumes

It can be difficult to avoid common odors, but it is important to identify triggers for asthma and inform your doctor if you experience any worsening symptoms. Taking regular preventer medication, as prescribed by a doctor, can help to reduce inflammation in the airways, meaning they are less likely to react to triggers.

In addition to asking friends and family to limit their use of perfumes, asthmatics can also avoid wearing perfumes themselves, and take steps to avoid other common triggers, such as secondhand smoke and fragrances in public spaces.

The mechanism by which exposure to pure, non-irritating odorants can elicit an adverse reaction in asthmatic patients is unclear

It is estimated that 2.5 million people in the UK find that fragrances such as perfumes or aerosols trigger their asthma symptoms. However, the mechanism by which exposure to pure, non-irritating odorants can elicit an adverse reaction in asthmatic patients is still unclear and may involve both physiological and psychological processes.

Physiological processes

Asthma is an inflammatory disease that causes the muscles around the airways to go into spasm, resulting in shortness of breath, wheezing, chest tightness, and coughing. Fragrances can act as triggers for these symptoms, likely due to particles in the air that are breathed in and irritate the airways, making them more inflamed and narrow. This can lead to wheezing, coughing, a tight chest, and potentially life-threatening asthma attacks.

Psychological processes

The perception of an odor as harmful or irritating may also play a role in triggering asthma symptoms. Expectations and beliefs about the potential harm of a fragrance can affect airway physiology and impact asthma exacerbations. For example, in a study where asthmatic participants were exposed to a fragrance described as either eliciting or alleviating asthma symptoms, those who believed the fragrance to be harmful reported higher levels of bronchoconstriction, hyperventilation, and panic.

Other factors

In addition to physiological and psychological processes, other factors may also contribute to the adverse reactions observed in asthmatic patients exposed to pure, non-irritating odorants. These factors include individual differences in sensitivity to specific fragrances, the presence of other triggers or allergens in the environment, and the duration and intensity of exposure to the odorant.

While the exact mechanism remains unclear, it is evident that exposure to pure, non-irritating odorants can elicit adverse reactions in asthmatic patients. Further research is needed to fully understand the complex interplay of factors contributing to this phenomenon.

Perfumes are triggering because they are commonly made with chemicals derived from coal tar and petrol

Fragrances and strong odors have been known to trigger asthma symptoms in many sufferers. Asthmatics often express concerns about the impact of airborne chemical exposure on their health, and these concerns are heightened when emissions are odorous. Perfumes are particularly triggering because they are commonly made with chemicals derived from coal tar and petrol.

Coal tar is a thick, dark liquid that is a by-product of coke and coal gas production from coal. It is composed of approximately 10,000 chemicals, of which only about 50% have been identified. Many of these constituents, including polycyclic aromatic hydrocarbons, benzene, toluene, and xylene, are known carcinogens. Coal tar has a very unpleasant odour and is used as a fixative in perfumes to make them evaporate slowly and emit odours for longer.

Perfumes and colognes are so commonplace that asthmatics encounter them almost every day. However, identifying these as triggers can help manage symptoms. Other common sources of triggering chemicals include nail polish and remover, wood-burning stoves and fireplaces, carpet and flooring materials, and paint and paint thinner.
