Hay Fever Suffering Statistics

Hay fever season is dreaded by sufferers around the world. But how many people in the UK suffer from hay fever?


Is that number increasing, and does the condition come with further health implications? Chemist 4 U has undertaken research into the subject in order to answer these questions and more and provide the most comprehensive and up to date UK hay fever study of 2019.



How Many People Suffer From Hay Fever In The UK?

According to NHS data, approximately 20% of UK residents are hay fever sufferers.


The results of a survey with a sample size of 2,245 respondents found that individuals aged 45-54 were most likely to be affected by hay fever allergies, with 25% of this age group claiming to have the condition. Only slightly fewer people aged 35-44 were sufferers, with this figure sitting at less than half a percentage below the older age group’s, while 25-34-year-olds saw 23% of their number complaining of reactions to pollen. Those who suffered the least appeared to be the youngest and eldest age groups surveyed, with just 19% of 16-24-year-olds saying they have a hay fever allergy, and 22% of 55-64-year-olds claiming the same.

These hay fever statistics suggest that UK residents are more likely to complain of hay fever than of almost any other ongoing condition, including asthma, diabetes, high cholesterol, migraines, physical disabilities, skin conditions and sleeping problems. The only categories that come close are mental health problems in those aged 16-19 and arthritis and high blood pressure in people aged between 55 and 64.


Hay fever is the most common of these conditions for both men and women, with female respondents suffering the most at 27%. 19% of men said they had a hay fever allergy by contrast. In women, the two next most common conditions were migraines and mental health conditions, while for men they were asthma and mental health issues.

Has Hay Fever Increased In The UK?

Reports suggest that between 2016 and 2017 alone, the number of adults claiming to have experienced bouts of hay fever rose from 26% to 31% - a leap of 19%.


According to the Telegraph, bouts of hay fever are increasing considerably in UK residents in mid-life.


There is currently no clear answer when it comes to the question of what is to blame for these increasing hay fever statistics. Many scientists argue that children’s immune systems are no longer developing properly as a result of a reduced amount of time outside, meaning less exposure to endotoxins.


Greater exposure in early life may help to strengthen the ability to fight hay fever.



What Causes Hay Fever?

Hay fever is principally an allergic reaction to pollen, but it can also be triggered by other allergens such as dust mites, or the saliva and skin particles shed by animals. The body’s immune system responds to the allergen as they would to a dangerous or poisonous substance, producing histamine and leukotrienes, inflaming the eyelids, nasal passage and sinuses and causing sneezing.


Pollen is the main trigger of hay fever and can be divided into several groups, each of which is prevalent at a different time of year. Among the most common are:


  • Tree pollen - early spring
  • Grass pollen - late spring and summer
  • Ragweed pollen - autumn


Fungi and mould spores can also cause hay fever but may be present all year round depending on the type. Hay fever caused by animal dander and dust mites will persist throughout the year but may become worse when windows are kept closed in colder winter months.




Pollen Count Statistics

Hay fever symptoms are at their worst when pollen counts are high. Because sufferers are triggered by different types of pollen, the worst time of year for each individual person will depend on when the pollen count is highest for the plant that triggers their allergies.


Regional Pollen Count Statistics

Different types of pollen see higher or lower counts depending on the area of the UK in which they are found.


For example, grass pollen is at its most prevalent in the western and northern regions and is at its worst in June, while nettle pollen is most intense in the south and east, especially in both June and July. Ash pollen is common right across the country, but the densest patches are in central and southern England and its effects are felt most in April.

UK Pollen Calendar 

Pollen from different plants affects the UK for most of the year, although October, November and December see extremely low levels. This means that hay fever season in the UK starts in January and ends in September, though its height is in late spring and early summer.


Late winter and early spring see pollen count peaks for:

  • Hazel
  • Yew
  • Alder
  • Elm
  • Willow
  • Poplar


Late spring and early summer are peak times for:

  • Birch
  • Ash
  • Plane
  • Oak
  • Pine


Midsummer is the worst time for:

  • Grass

The plants with the longest pollen seasons are hazel, yew and alder trees along with grass and nettle.



Hay Fever Remedies Statistics

Antihistamines and other remedies can be taken to ease the symptoms of hay fever. Medicines and other treatments can come in the form of tablets, liquids, nasal sprays and others besides.


Most Popular Hay Fever Products

Remedies taken in tablet form are the most popular when it comes to treatment for hay fever. Usually, these can be bought over the counter and should be taken every four to six hours when needed to relieve symptoms, though there are also once-a-day options and other variations.

Hay Fever Tablets



Antihistamines are so named because they block the effects of histamine in the body, treating itching, sneezing and watery eyes but proving less effective against blocked or runny noses. Side effects of these medicines may include drowsiness. While remedies containing antihistamines are used to prevent or reduce the severity of allergic reactions, drinking alcohol during hay fever season is likely to exacerbate any symptoms due to its histamine content.


Nasal Decongestants

Nasal decongestants help to soothe and reduce the swelling, blockages and running in the nasal passage that commonly occurs as a result of hay fever. They usually contain corticosteroids, and may also cure itching, watery eyes. It’s also possible to opt for more powerful nose drops, which should be used sparingly for shorter periods of time. Side effects may include irritation and dryness of the nose, bleeding from the nose and an unpleasant taste in the mouth or an itchy rash around the nose, particularly if the spray is incorrectly used.


Corticosteroids can also be taken in tablet form.



Brands such as Optrex produce eye drops to reduce the itching and swelling of the eyes that sometimes results from hay fever. They often contain antihistamines and may also contain the anti-inflammatory ingredient Sodium Cromoglicate. Side effects may include stinging or burning sensations in the eyes.



Severe cases of hay fever may be treated by immunotherapy - remedies administered by a specialist doctor to desensitize the immune system in order to reduce symptoms. This is usually done by taking small doses of the allergen over a three-year period to allow the body to adjust to its presence. The dose may be administered via injections, drops or a tablet that dissolves under the tongue. After the initial dose, others can be taken at home.


Sales of Hay Fever Products

Globally, 65% of hay fever remedies used are antihistamines, 29% are intranasal corticosteroids and 4% are types of immunotherapy. Just 1% of people use other treatments.

Between 2016 and 2018, there was an approximate 54% increase of interest in the purchase of hay fever products, which correlated with the severe hay fever season in 2018, which was reported to be the worst in a decade as the result of the suddenness of the incoming period in May after a wet March led to a delay in the phenological Spring.


Sales of hay fever products have increased by 6% worldwide throughout the past year, and, according to Kantar Worldpanel’s hay fever statistics, UK shoppers saw 21% of their number - around 10.7 million people - buy a hay fever product in the first three months of 2019. The fastest growing markets were in nasal sprays and eye drops.

While tissue sales are usually comparatively low in summer, July 2018 saw a 3.6% rise in sales of travel packs because of the severity of the pollen count - which caused hay fever symptoms in around a third of all UK adults.



Types Of Hay Fever Statistics UK

Different pollens and other allergens affect sufferers at different times of the year. Each individual reacts to the allergen in question in different ways.


Most Common Types Of Hay Fever

95% of hay fever sufferers are allergic to grass pollen, making it the most common allergen.

Those whose immune systems are triggered by grass pollen may experience a runny or blocked nose, itchy or streaming eyes or an itchy mouth or throat. Less common types of hay fever are those that see sufferers come out in hives or get headaches during hay fever season.

Extreme Cases Of Hay Fever

In extreme cases, sufferers can experience considerable swelling, itching and respiratory problems that have a severe impact on their day to day lives, sometimes causing them to take time off work or to seek specialist immunotherapy treatment.


80% of asthma sufferers say that their condition is triggered by hay fever, and where asthma is exacerbated by hay fever symptoms, there is the increased potential of a fatal attack.


According to the National Review of Asthma Deaths for the UK, in 2014, 15% of individuals who died after an asthma attack which was exacerbated by additional features did so while suffering from hay fever. The only exacerbating condition featuring in more deaths from asthma was a viral or upper respiratory tract infection, at 28%.

Other conditions that may be worsened by hay fever are sleep-related problems, sinusitis and ear infections.


Time Off Work Due To Hay Fever 

4 in 10 adults with hay fever say that their symptoms have made it difficult for them to do their job. As a result of this, 1 in 5 sufferers of hay fever has taken time off work when experiencing a bad bout. Within a study group of 1,660 hay fever sufferers, 19% said they had called in sick as a result. However, a third admitted to bending the truth about their reason for taking time off, as they were concerned that their employer would not consider it a valid reason.


Hay Fever Search Trends 

Between 2007 and 2017, the search interest in hay fever doubled.


The peak of this interest was in summer 2018. At their highest point, searches using the same or similar terms in 2012 hit only 25% of this number.
