Getting the jump on spring allergies

Respiratory specialist Dr Philip Masel encourages people with seasonal allergies to be aware of and avoid known triggers

With spring now here, many of us are looking forward to the warmer weather, greener grass and blooming flowers.

But for some people, spring brings a rise in immune-related health issues that require careful attention and management.

According to the Australasian Society of Clinical Immunology and Allergy (ASCIA), approximately 1 in 5 people living in Australia and New Zealand are affected by allergic rhinitis or hay fever, a condition commonly exacerbated by an increase in seasonal allergens.

The Prince Charles Hospital (TPCH) Respiratory Specialist Dr Philip Masel said that people with respiratory conditions like asthma and allergic rhinitis tend to have more immune flare ups during the warmer months because of increased pollen levels in the air.

“We see more flowering trees, appearance of different and grasses, and an increase in mould spores because of the humidity,” Dr Masel said.

“People with conditions like asthma and hay fever have an immune system that is more reactive to these types of allergens which can sometimes result in an allergic reaction.

“Unlike individuals without allergies, when these people inhale allergens, their immune system mistakes it for being harmful, and then goes into defence mode by releasing histamines which cause inflammation and spasms in their airway.

“If not treated, these immune flare ups can be very disabling and can result in life-threatening events such as throat swelling or severe drop in blood pressure. These flare up can sometimes also be accompanied by other types of allergies including skin-related reactions.”

Dr Masel said that certain weather conditions can also trigger allergic reactions in some people.

“During summer, increased haze, smoke from bushfires and thunderstorms can all cause a spike in allergens and chemicals in the atmosphere,” he said.

“It’s important for individuals with respiratory conditions to know the triggers so they are well prepared to manage any immune system flare ups.”

Dr Masel’s key tips to help people with respiratory conditions avoid and manage flare ups:

• Check in with your GP to ensure your asthma is well controlled and you are on adequate preventer medication. If allergies are not well controlled, ask your GP about a possible referral to an immunologist.
• Keep adequate preventor medication on hand at all times – flares up can happen unexpectedly and quickly.
• Know your individual triggers and avoid them if possible (e.g. pets, grass, perfumes, certain foods, certain types of alcohol, moulds).
• Make sure your house is cleaned and dusted regularly.
• For pet owners, remove pet hair from personal clothing, furniture, bedding and cars.
• Be aware that some pets like guinea pigs, rabbits and birds can also cause allergies.
• Avoid thick shag pile carpets and other floor coverings that hold dust.
• Steer clear of feather mattresses and opt for sealed doonas.
• Avoid contact with mould where possible. If you have to clean or touch mould for any reason, wear a mask and gloves.
•  Check the weather forecast for upcoming haze, smoke or thunderstorms. Subscribe to local council weather alerts.

“By being aware of and avoiding known triggers, people with allergies are much more likely to maintain better health during the spring season,” Dr Masel said.
