Hay Fever and Sleep: Why Allergies Wreck Your Nights and What Helps

Hay fever and sleep are a bad mix. A blocked nose, sneezing and itchy eyes are irritating by day, but at night they can keep you breathing through your mouth, waking often and dragging through the next morning. This guide covers why hay fever disrupts sleep, what the research says, which treatments help at night, how to make your bedroom less of a pollen trap, thunderstorm asthma, and when to see your GP.

The short answer: hay fever (allergic rhinitis) is linked with poorer sleep quality, more night waking, snoring and daytime sleepiness, even though total sleep time often looks normal. The most useful step is treating the nose properly, usually with a daily corticosteroid nasal spray, which trials show improves sleep-related quality of life. Keep pollen and dust mites out of the bedroom, rinse your nose before bed, and ask a pharmacist before choosing an antihistamine, since some cause drowsiness the next day. If symptoms are frequent or you have asthma too, see your GP.

Why hay fever wrecks your sleep

Hay fever is an allergic reaction in the lining of the nose. Common triggers include grass, weed and tree pollens, dust mites, animal fur or skin flakes, and mould. Some people react only in spring, others all year round. Healthdirect lists interrupted sleep as one of the effects of untreated hay fever, leading to tiredness during the day that can affect work and school (source).

Several things go wrong at night:

• A blocked nose pushes you to breathe through your mouth, which can mean snoring and a dry mouth by morning. See waking up with a dry mouth.
• Lying down makes congestion feel worse for many people.
• Sneezing and itching wake you or stop you settling.
• Bedding and carpet can hold dust mites and pollen right next to your face.

It's common, too. The Australasian Society of Clinical Immunology and Allergy (ASCIA) says allergic rhinitis affects around 18% of people in Australia and New Zealand, and lists sleep disturbance and daytime tiredness among the effects of severe symptoms (source).

What the research says

A 2020 systematic review pooled 27 observational studies. People with allergic rhinitis reported worse sleep quality, took longer to fall asleep and had more insomnia, restless sleep, snoring and sleep-disordered breathing, plus more difficulty waking up, daytime sleepiness and morning headaches. There was no significant difference in sleep duration. The authors rated the quality of evidence low to very low, so the findings show a link rather than proof of cause (source).

That pattern matters. You might spend a normal number of hours in bed with hay fever and still wake up feeling unrefreshed, because the sleep is broken and shallow rather than short. If that sounds familiar, see still tired after 8 hours of sleep.

Treatments that help at night

Treating the nose is the main way to protect your sleep. Talk to a pharmacist or GP about what suits you.

Option	What it does	Night-time notes
Corticosteroid nasal spray	Reduces inflammation in the nose	Works best used every day, not just on bad nights
Non-sedating antihistamine	Eases sneezing, itch and runny nose	Usually doesn't cause sleepiness, but can in some people
Sedating antihistamine	Same, but makes you drowsy	Can leave you groggy the next day; ask first
Saline spray or rinse	Washes pollen out of the nose	Useful just before bed
Antihistamine eye drops	Settles itchy, watery eyes	Handy if eyes are what keep you up

A 2025 meta-analysis of 18 randomised trials with 6,019 participants found intranasal corticosteroids significantly improved the sleep part of a hay fever quality-of-life questionnaire. They didn't significantly change daytime sleepiness scores, and the results relied on questionnaires rather than sleep studies (source).

On antihistamines, healthdirect notes that sedating types can make you sleepy and that even non-sedating ones make some people drowsy, so take care driving or operating machinery. Sedating antihistamines should not be given to children under 2 for any reason (source).

Make your bedroom less of a pollen trap

1. Shower and wash your hair before bed in pollen season, so you're not carrying pollen onto your pillow.
2. Keep bedroom windows closed on high-pollen, windy days. Use air conditioning if you have it. See sleeping with the window open for the trade-offs.
3. Wash bedding weekly in hot water and use dust mite covers on pillows and the mattress.
4. Consider drying sheets inside during pollen season. Some people find line-dried bedding sets them off.
5. Keep pets off the bed if pet dander is a trigger. See sleeping with pets.
6. Rinse your nose with saline before you turn the light off.
7. Try raising your head slightly with an extra pillow. Some people find congestion eases a little.

If you're also battling a cold, the same congestion tips apply; see how to sleep with a cold or flu.

Thunderstorm asthma

In south-eastern Australia, spring hay fever has an extra risk. Better Health Channel explains that in Victoria the grass pollen season usually runs from 1 October to 31 December, and certain storms can break pollen into tiny particles that reach deep into the lungs. People with current or past asthma, or springtime hay fever, are at risk, and the risk is higher with both, especially if asthma is poorly controlled (source). Know asthma first aid, and call triple zero (000) if someone is struggling to breathe.

When to see your GP

See your GP if:

• Symptoms are persistent, which healthdirect describes as four or more days a week for four or more weeks, or moderate to severe.
• You snore loudly or wake gasping, since sleep-disordered breathing is more common with allergic rhinitis. See signs of sleep apnoea.
• You have asthma or wheeze, especially in spring.
• Over-the-counter treatments aren't working. Allergy testing and other treatments may help.

Where the Sovune Nudge fits

We make the Sovune Nudge, a vibrating alarm wristband, so we're not neutral. It does nothing for hay fever. Where it can help is the morning after a broken night, when you need to get up without waking a partner who has also been listening to you sneeze.

• Silent. No speaker, no sound and no light in the room except a small display when you press the button.
• Wakes you with vibration on your wrist, starting as a gentle tap and building through three intensity levels.
• Each alarm vibrates for a full minute, and you can switch it off sooner on a groggy morning.
• Water-resistant for everyday use, so a pre-bed shower to rinse off pollen is fine.

It comes with a 30-day money-back guarantee.

Quick answers

Why is my hay fever worse at night? Many people find congestion feels worse lying down, and pollen or dust mites in bedding sit right by your face. Showering before bed and washing bedding weekly helps.

Can hay fever make you tired even if you sleep 8 hours? Yes. Research suggests sleep quality suffers more than sleep length, so you can spend long enough in bed and still wake unrefreshed.

Should I take a drowsy antihistamine to help me sleep? Ask your pharmacist first. Sedating antihistamines can leave you groggy the next day and aren't suitable for everyone.

Does a nasal spray help sleep? Trials show daily corticosteroid nasal sprays improve sleep-related quality of life in people with hay fever. They work best used regularly.
