Around one in five people in the UK has hay fever, and June is peak season for grass pollen, the most common trigger for allergic rhinitis in Britain.1 If your symptoms feel harder to control right now, that's not your imagination. Grass pollen counts tend to peak from late May through to mid-July, with counts spiking on warm, windy afternoons. These five hay fever tips are grounded in clinical evidence and can make a real difference to how you feel over the next few weeks.
1. Start Your Antihistamine Before Symptoms Hit
Taking an antihistamine after your symptoms have already taken hold is less effective than starting before pollen exposure. Antihistamines work by blocking histamine receptors before the inflammatory response gets going. Once histamine has already been released in significant quantities, the cascade is harder to interrupt.
Asthma and Lung UK recommends taking antihistamines two to four weeks before your symptoms typically start for the best protection.1 If you've already missed that window, starting now will still help, though consistent daily dosing gives better results than taking a tablet only on bad days.
For daytime use, a non-drowsy second-generation antihistamine is the recommended choice. Both fexofenadine and cetirizine are effective once-daily options that are less likely to cause drowsiness than older antihistamines such as chlorphenamine. Individual responses vary, and if one doesn't give adequate relief after two weeks, it's worth trying the other.
2. Layer Your Treatment: Add a Nasal Spray
If an antihistamine alone isn't fully controlling your symptoms, adding a steroid nasal spray is the clinically recommended next step. This is particularly useful for nasal congestion, which antihistamines are less effective at addressing.
Steroid nasal sprays work by reducing inflammation in the nasal lining rather than simply blocking histamine. They take several days to reach their full effect, and in some people it can take up to two weeks.2 Starting one now will still help build protection through the rest of the grass pollen season.
A saline nasal rinse used before applying a steroid spray can improve how well it works by clearing pollen from the nasal passages first.3 Both steroid nasal sprays and saline rinses are available over the counter from UK pharmacies without a prescription.
3. Check the Pollen Count and Adjust Your Day
The Met Office publishes a five-day pollen forecast updated daily. During grass pollen season, it's worth checking it as part of your morning routine. On high or very high pollen days, simple changes to when and where you spend time outdoors can meaningfully reduce your exposure.
Pollen counts are highest on warm, dry, windy days. Plants release pollen early in the morning, and counts can rise again in the early evening as the air cools and pollen descends.4 Scheduling outdoor activities for early morning or evening, keeping car windows closed, and using air conditioning on recirculate rather than drawing in outside air can all reduce the total pollen load you encounter on a given day. Keeping bedroom windows closed at night is especially worth doing during high-count periods, as pollen that settles on soft furnishings and bedding can prolong symptoms overnight.
4. Use Vaseline Around Your Nostrils
Applying a thin layer of Vaseline (petroleum jelly) around the outside of your nostrils creates a physical barrier that traps pollen before it can enter the nasal passages and trigger an allergic response. It's one of the most practical low-cost hay fever tips available, and one that's often overlooked.
The NHS and Asthma and Lung UK both recommend this approach as part of a broader hay fever management strategy.1 It's particularly useful when you know you're going to be outside for an extended period on a high-pollen day. It costs very little and can be combined with any other treatment without interaction. Apply it around the nostrils rather than inside them, as applying inside can impair natural nasal drainage.
5. Shower and Change Clothes When You Come Inside
Pollen is sticky. It clings to hair, clothes, and skin, and when you bring it indoors, it continues to provoke symptoms long after you've left the outdoors. A simple routine of showering and changing into fresh clothes when you return home can significantly reduce your total daily pollen exposure, particularly on high-count days.
Asthma and Lung UK recommends this as a standard hay fever management step.1 Pay particular attention to hair, which traps pollen more effectively than smooth skin. Washing your face and rinsing your eyes with clean water after time outdoors also helps. Avoid drying laundry outside during grass pollen season, as clothes left on a line collect pollen and bring it back inside with you.
Frequently Asked Questions
What helps with hay fever when nothing seems to work?
If standard antihistamines aren't providing adequate relief, the most effective next step is to add a steroid nasal spray to your routine. Using both together addresses different parts of the allergic response: the antihistamine targets histamine-driven symptoms like sneezing and itching, while the steroid spray reduces underlying nasal inflammation and congestion. If this combination still doesn't control your symptoms, speak to a pharmacist or GP, as prescription-strength options or allergy testing may be appropriate.
What's the best non-drowsy antihistamine for hay fever?
Fexofenadine and cetirizine are both effective non-drowsy second-generation antihistamines for hay fever, taken once daily. Fexofenadine is generally considered the least sedating option, while cetirizine may be more effective for some people and acts slightly faster. Individual responses vary, so if one doesn't work well for you after two weeks of consistent use, it's worth trying the other. Loratadine is another well-tolerated once-daily option. Avoid older antihistamines such as chlorphenamine (Piriton), which cause significantly more drowsiness and can impair driving and concentration.
When should I take antihistamines for hay fever?
For best results, take your antihistamine at the same time each day throughout the pollen season rather than only on symptomatic days. If your antihistamine causes any drowsiness, taking it in the evening can reduce the impact on your daytime functioning. Starting two to four weeks before your symptoms typically begin each year gives the best protection, as recommended by Asthma and Lung UK.1
Does Vaseline actually help with hay fever?
Yes. Applying a thin layer of Vaseline around the outside of both nostrils creates a physical pollen trap that prevents some airborne pollen from entering the nose. It's not a substitute for antihistamines or nasal sprays, but it's a useful additional measure, especially before spending time outdoors on high pollen days. Both the NHS and Asthma and Lung UK recommend it as part of hay fever management.1
Why is hay fever worse at certain times of day?
Grass pollen is released throughout the day but tends to be most concentrated in the late morning and late afternoon, when it rises into the atmosphere with warming air and disperses on the breeze. Counts can also be high in the evening as the air cools and pollen descends again. Checking the daily pollen forecast and scheduling outdoor activities for early morning, before pollen counts have peaked, is one of the most practical ways to reduce your exposure on high-count days.
