Pollen is a powdery substance produced by flowering plants, angiosperms, when they reproduce.
Pollen can trigger symptoms of asthma, a chronic condition in which the small tubes that carry air to and from the lungs become blocked and make it difficult to breathe.
According to Asthma Australia, one in five people residing in Adelaide, the 'Garden City of Australia', live with hay fever and/or asthma.
For this reason, Asthma Australia helps coordinate the Adelaide Pollen Count, a daily report of grass pollen levels from the past 24 hours.
In this article, we will look at why pollen counting is vital to the wellbeing of asthma sufferers in Adelaide.

As we mentioned earlier, pollen triggers symptoms of asthma.
Asthma is a chronic condition in which the airways become narrow and make it difficult to breathe.
Severe asthma attacks are generally characterised by shortness of breath or wheezing and can be life-threatening without prompt treatment.
There are 3 main factors that cause the airways to narrow:
The inside lining of the airways inflames and becomes red and swollen
The muscle around the airways constricts or tightens
The airways produce extra mucus
The exact cause of asthma is unknown, though it is thought to encompass a combination of environmental and genetic factors.
Rather, various irritants that commonly trigger allergies (allergens) can trigger symptoms of asthma. Pollen is one such trigger - other triggers can include:
Airborne allergens, including dust mites, mould spores, and animal dander
Respiratory infections, such as the flu and common cold
Exercise
Air pollutants or irritants, including cigarette smoke and perfume
Changes in temperature and weather, especially exposure to cold air
The tell-tale signs of a pollen allergy can include a runny nose, watery eyes, and itchy skin.
Why pollen counts are important
Pollen counts, including the Adelaide Pollen Count, measure the number of pollen grains in a cubic metre of air.
They are used by pollen indexes, such as the Brisbane Pollen Index, to forecast the likelihood of allergic reactions among susceptible people.
This information can help asthma sufferers take the necessary precautions to reduce their exposure to pollen and the risk of an asthma attack. These precautions can include:
Staying indoors on days of high pollen count
Using allergy relief options, such as nasal sprays
Cleaning surfaces regularly to avoid the accumulation of dust
Changing your clothes and taking a shower after being outdoors, to remove any pollen you may have picked up
Final thoughts
Asthma is a chronic condition in which the airways narrow and make breathing difficult.
Though the exact cause of asthma is unknown, symptoms of asthma can be triggered by common allergens, including pollen.
Pollen counts, such as the Adelaide Pollen Count, and pollen indexes provide day to day forecasts on the level of pollen in the air. As such, they are vital in helping asthma sufferers reduce their exposure to allergens and the risk of an asthma attack.

During pregnancy, it is important for women to continue taking their asthma medication. Though some women feel uneasy about continuing their asthma medication during pregnancy, asthma attacks can put unborn babies at risk.
World Allergy Week highlights the severity of Anaphylaxis. Anaphylaxis is an acute, potentially life threatening hypersensitivity reaction. It is important to know first aid for anaphylaxis, as the reaction develops rapidly.
Winter is also the season for the flu, as well as colds and other infections of the respiratory system, which are known to exacerbate the symptoms experienced by asthmatics.
