Why Some Adults Suddenly Develop Hay Fever

Why Some Adults Suddenly Develop Hay Fever

It can feel bewildering to develop hay fever for the first time as an adult, especially if you spent every childhood summer outdoors without a single sneeze. Yet it happens more often than you might think. Around one in five people with hay fever first develop symptoms after the age of twenty, and understanding why can make the change a little less unsettling.

It Often Comes Down to Genetics

Susceptibility to allergies is largely inherited. As many as one in three people carry antibodies to common allergens such as pollen, even if they have never had a reaction. As allergist Dr Runa Ali explains, most people only carry antibodies to viruses and bacteria, but a significant number of us also carry them for things like pollen or peanuts, without ever knowing it.

Carrying these antibodies does not guarantee you will ever develop symptoms. It simply means your immune system has the potential to react, and something later in life can tip the balance.

What Can Trigger It Later in Life

Researchers are still working out exactly why some people develop active symptoms while others with the same genetic susceptibility never do. A few factors are thought to play a role:

• Significant infections. A severe respiratory illness, such as pneumonia, may shift how the immune system responds to allergens afterwards
• Pollution exposure. Long term exposure to air pollution is thought to increase the likelihood of allergic reactions developing
• Hormonal changes. Shifts in hormones, including those linked to pregnancy or the menopause, are sometimes associated with new allergies appearing
• A change in environment. Moving to a new area with different plants and pollen types can expose you to allergens your immune system has not encountered before

Interestingly, avoiding pollen altogether is not necessarily protective for people with mild sensitivities. Some ongoing exposure appears to help the immune system maintain a degree of tolerance, so the relationship between exposure and developing symptoms is not always straightforward.

Recognising Adult Onset Hay Fever

Because it is unexpected, new hay fever in adulthood is often mistaken for a persistent cold. It is worth considering hay fever if you notice:

• Watery, itchy eyes
• A blocked or runny nose that does not come with a fever
• Sneezing and coughing that appear at the same time each year
• Symptoms that improve indoors or after rain, when pollen counts drop

A pharmacist or GP can usually confirm hay fever quickly, and in some cases an allergy test can identify exactly which pollens are responsible.

Managing New Hay Fever

Whether your hay fever started at seven or seventy, the day to day management is much the same. Reducing your pollen exposure, keeping windows closed during peak pollen hours and washing bedding regularly all help. Many people also find that supporting their respiratory system nutritionally makes a real difference through the season.
