You can tell a lot about a British summer by the way someone walks out of the back door. The first warm Saturday in June, garden chairs dragged across the patio, and within ten minutes a familiar itch starts behind the eyes. Hay fever arrives quietly, then makes itself at home until September.

Most of the advice out there is either vague — avoid pollen — or unrealistic, like staying indoors for eight weeks. You don't need to cancel your summer. You need a plan that matches the way pollen actually behaves in this country, and a handful of habits that cut your exposure without much effort.

Know what's in the air, and when

Hay fever isn't one season. It's a relay race of different pollens, and knowing which leg you're in makes everything else easier.

• Tree pollen — roughly late March to May, with birch, oak, ash and hazel the usual suspects. If your symptoms start in spring before the grass has even grown, trees are probably your trigger.
• Grass pollen — mid-May through July, often at its worst in June. This is the most common hay fever trigger in the UK, and the reason so many people feel dreadful just as the good weather arrives.
• Weed pollen — June to September, from nettle, dock and mugwort. It catches out anyone who assumed they were safe once the grass stopped flowering.

Within that, pollen follows a daily rhythm. Counts are usually higher on warm, dry, breezy days and lower after steady rain, which washes grains out of the air. Thunderstorms can do the opposite, breaking pollen into smaller fragments that travel further into the airways. Exact timing shifts with pollen type and weather, so check a daily pollen forecast for your area rather than following a fixed rule. It takes ten seconds, and it turns guesswork into planning.

Move your outdoor exercise, don't abandon it

If you run, cycle or garden, the aim is to pick your moments. On a high-count day, a hard session in the wrong place at the wrong time will undo a week of sensible habits.

Rain is your friend. The hour or two after a decent shower is often the cleanest window of the day, and a seafront path is generally kinder than a sheltered inland park, where the air sits still and pollen settles. Freshly cut grass, verges being mown and quiet woodland paths in tree season are all worth avoiding.

Kit matters more than people expect. Wraparound sunglasses keep pollen out of your eyes, a cap keeps it out of your hair, and a thin smear of barrier balm — plain petroleum jelly does the job — around the nostrils traps grains before they get further in. Wash your face and hands when you get back, and change your top if it's damp with sweat and pollen.

One caveat: if your chest tightens or you wheeze during or after exercise, that deserves a conversation with your GP rather than another antihistamine.

The first ten minutes home

Pollen doesn't stay outside. It arrives on hair, shoulders, shoes and dog fur, then settles — on the sofa, on the bedding, on the pillow you'll spend eight hours pressed against.

The fix is a routine rather than a deep clean. Shoes off at the door. Outdoor clothes into the wash basket instead of over a chair. A quick shower before bed, and a rinse through your hair even on the days you don't wash it. Pillowcases changed every few days during peak weeks.

Keep the washing line for towels, not sheets, on high-count days. Laundry acts like a net, and you'll end up wearing the catch. Pets deserve a mention too: a wipe down with a damp cloth when they come in makes a surprising difference, especially if they sleep on your bed.

Windows, bedrooms and the air you breathe at night

The instinct to fling every window open in July is understandable and often counterproductive. On high-count days, keep bedroom windows shut during the day and ventilate when levels drop — early morning or after rain, depending on what's in the air. A fan won't remove pollen, but it does make a hot, closed room far more bearable.

Dust with a damp cloth rather than a dry duster, which simply lifts settled pollen back into the air. Vacuum earlier in the day rather than just before bed, so anything disturbed has time to settle again, and wash bedding regularly since fabric holds pollen as readily as it holds dust. In the car, keep windows closed on motorways and country lanes alike, use the recirculation setting, and think about the cabin filter if the air feels stale.

When symptoms flare anyway

Some days the plan won't hold. A saline nasal rinse can clear pollen from the nose; use sterile, distilled or previously boiled and cooled water, or ready-made saline sachets, and never untreated tap water. A cool, damp flannel over closed eyes eases itching, a warm shower before bed helps with the restless feeling, and keeping hydrated is quietly useful.

If you use antihistamines or eye drops, follow the label or your pharmacist's advice rather than doubling up when a day goes badly. And if symptoms are disrupting sleep, work or breathing, get proper help: hay fever and asthma often sit together, and persistent wheeze, chest tightness or breathlessness needs assessment. If you're pregnant, breastfeeding or taking other medication, check before adding anything new.

Your summer hay fever checklist

1. Check the pollen forecast before you plan your day — especially before exercise or gardening.
2. Time outdoor activity for after rain, and choose coastal or open, breezy routes.
3. Take sunglasses, a cap and barrier balm with you as standard.
4. Shower and change when you get home; shoes at the door.
5. Keep bedroom windows shut on high-count days, and ventilate when levels fall.
6. Change pillowcases often; keep laundry and pets out of the bedroom where you can.
7. Damp dust, vacuum earlier in the day, and keep the car windows up.

Start with the two easiest: check the forecast each morning and shower before bed. Those alone change how a British summer feels for a lot of people. Build the rest in as the season goes on, and you can enjoy June rather than simply endure it.
