Managing seasonal allergies: supporting your workforce

Seasonal allergies, including hay fever, affect around one in four adults in the UK. With many of those individuals in full-time work, symptoms such as sneezing, itchy eyes, fatigue and poor sleep can have a noticeable impact on daily performance and wellbeing. 

Although allergies are common, their effect on productivity and concentration is often underestimated. The good news is that, with the right awareness and small practical changes, much of this impact can be reduced. 

What are seasonal allergies? 

Hay fever (also known as allergic rhinitis) occurs when the immune system reacts to substances such as pollen. This reaction triggers inflammation in the nose, eyes and airways, leading to symptoms like congestion, sneezing, and watery eyes. 

In the UK, hay fever season typically peaks between late May and July due to high grass pollen levels. Earlier in the spring, tree pollen is more common, while weed pollen and mould spores can extend symptoms into autumn. Some people experience symptoms all year round, often due to indoor allergens such as dust mites, pet dander or mould. 

Why allergies matter at work 

Allergy symptoms can affect more than physical comfort. Poor sleep, ongoing irritation, and even side effects from medication can reduce focus and slow cognitive performance. As a result, employees may struggle with concentration, experience fatigue, or find it harder to maintain productivity throughout the day. 

Recognising and supporting employees during allergy season can therefore play an important role in maintaining both wellbeing and performance. 

Managing symptoms effectively 

The most effective way to manage allergies is to reduce exposure to triggers where possible and use appropriate treatments. Common options include: 

• Antihistamines, including non‑drowsy formulations suited to working hours 

• Intranasal corticosteroid sprays 

• Saline nasal sprays and eye drops 

• Combination prescription treatments, such as sprays containing both antihistamines and corticosteroids 

For individuals with more severe or persistent symptoms, a GP may recommend further treatment or referral to a specialist for immunotherapy. 

Reducing exposure to pollen 

Simple day‑to‑day habits can help limit exposure during high pollen periods. Sharing the following guidance with employees can help them limit their exposure during high pollen periods. 

During the day: 

• Keeping windows closed during peak pollen times, typically early morning and evening 

• Avoiding grassy or rural areas on warm, dry days 

• Avoid drying clothes outside when pollen counts are high 

• Use recirculated air in cars and keeping windows closed when driving 

• Check daily pollen forecasts for local conditions 

After being outdoors: 

• Shower and change clothes after spending time outside 

• Use saline rinses to help clear allergens from nasal passages 

For medication timing: 

• Start antihistamines before symptoms typically begin and continue through the season 

When symptoms persist 

If an employee’s symptoms continue outside of pollen season, indoor allergens may be the cause. House dust mites are a common trigger and are often found in bedding, carpets and soft furnishings. 

Employees can reduce their exposure by: 

• Washing bedding regularly at 60°C or above 

• Using allergen‑resistant mattress and pillow covers 

• Vacuuming frequently using a HEPA‑filter vacuum 

• Reducing soft furnishings where possible 

• Keeping sleeping areas clean and well‑ventilated 

Addressing indoor triggers can be especially important for employees experiencing symptoms year‑round. 

When to seek further advice 

While many people manage allergies effectively with over‑the‑counter treatments, some symptoms should be reviewed by a healthcare professional. 

Employees should consider speaking to a GP if: 

• Symptoms are persistent or severe 

• Over‑the‑counter treatments are not providing relief 

• Sleep or daily activities are significantly affected 

• Breathing difficulties occur 

• There is a link to conditions such as asthma or eczema 

Early advice can help ensure the most appropriate treatment and reduce the longer‑term impact on health and wellbeing. 

Supporting employees during allergy season 

Employers can play an important role in reducing the impact of seasonal allergies. Practical steps include: 

• Sharing guidance ahead of peak pollen periods to help employees prepare 

• Supporting flexible working arrangements where possible 

• Managing indoor environments by reducing dust and maintaining air systems 

• Signposting available health and wellbeing support services 

These simple measures can help employees feel more comfortable, maintain focus, and stay productive. 

Taking a proactive approach 

Seasonal allergies are a common and manageable condition, but they can have a meaningful impact if left unaddressed. By understanding triggers, recognising symptoms, and encouraging early action, employers and employees can take simple steps that reduce disruption, protect productivity, and support wellbeing throughout allergy season.
