Get ready for spring - hay fever worse in spring than summer
Date:12/20/2011

Hay fever (runny nose, sneezing, itchy eyes) is caused by an allergy to pollen, and most commonly to grass pollen. These tiny grains bring misery to sufferers through spring and summer and pollen levels are often included as part of weather reports to help sufferers prepare. However new research published in BioMed Central's open access journal Clinical and Translational Allergy shows that, regardless of medication and other allergies, for the same grass pollen levels, hay fever symptoms are worse in the first half of the season than later on.

Worldwide there are over 10,000 species of grass and most of these species are able to cause symptoms in people who have hay fever. The different species release their pollen sequentially so that, for a sufferer, hay fever, also called seasonal allergic rhinitis, can last for the whole three months that grasses are flowering.

Researchers from Netherlands compared daily pollen counts with daily symptoms reported by hay fever sufferers (with a positive skin test to grass pollen) living around Leiden. The people involved in the study were also tested for other common allergies including birch pollen (birch releases its pollen just before the start of the grass pollen season), house dust mites, dogs and cats. The study covered the consecutive hay fever seasons of 2007 and 2008.

Symptoms of hay fever definitely matched the concentration of pollen in the air and also the amount of medication taken. Higher medication use was seen during days with high pollen counts and severe symptoms, while less medication was taken on days with low pollen counts and milder symptom severity.

Surprisingly the symptom scores at the beginning of the season were higher than scores at the end of the season for a similar pollen count. This could not be accounted for by medication taken such as antihistamines, nor by the long term use of nasal steroids. The birch pollen season precedes grass pollen and ov
