Allergy symptoms can be uncomfortable at the best of times – never mind when you’re trying to sleep.
However, if your runny nose or itchy eyes are keeping you up all night, there are a few things you can do to help keep your symptoms in check1.
Read on to learn about how allergies impact sleep, and what causes night-time allergies. We’ll also cover how simple measures can help to prevent symptoms flaring up, and can hopefully allow you to enjoy a restful night’s sleep.
We’ll explore:
How do allergies impact sleep?
If you can't sleep because of allergies, you’re not alone. Studies have shown that allergies and nasal congestion can cause people to wake during the night. They can also make it hard to fall asleep in the first place2.
Can you sneeze in your sleep?
The body’s biological responses and mechanisms mean that sneezing cannot occur during sleep3. However, if you suffer with allergies and are having difficulty to breathing, you may wake up3.
If you are sneezing at night when you go to bed, it certainly can impact your ability to fall asleep. Sneezing can occur when people experience an allergic reaction, along with itching and other uncomfortable symptoms. This can then lead to a range of other breathing problems that may make it difficult to sleep2.
Why are allergies worse at night?
Research has shown that lying down in bed can make our allergies worse during the night4. That’s because when we lie down, the fluid in our nose and nasal passage can begin to drip down our throat4. This can then result in coughing, wheezing, difficulty breathing and other symptoms that can keep us awake at night4.
What causes night allergies?
Night allergies occur when the body reacts to an allergen5. Often, our bodies can mistake regular things such as pollen, dust or animal fur as a threat, and this can trigger an allergic reaction5.
If you’ve noticed your allergy symptoms only happen at night, you may be allergic to something that’s prevalent in your bedroom2. For example, dust mites are a common type of allergen found in bedroom spaces. They can live in your bedding and cause your allergies to play up during the night2.
Additionally, if the humidity level in your bedroom is over 40%, mould can begin to grow on your carpet, curtains, bedding and furniture – which could then trigger an allergic reaction2.
There are also a variety of other factors that could cause night allergies, such as pet dander if you have a cat or dog, and pollen if you’re leaving your windows open. It’s worth doing a test to determine the exact cause of the irritation1.
If you suffer from hay fever, you may experience seasonal sleep disturbances between late March and September, when the pollen count tends to peak6.
How to relieve allergies at night
The first step to managing your allergies is to find out your allergy triggers and limit your exposure to them1.
Here are a few ways you can do this to help calm your allergies during the night:
Stop pets from going in the bedroom, to prevent pet dander from spreading to your pillows, duvet and blankets1.
Vacuum your bedroom regularly, including your carpets and upholstery, to remove dust mites and pet dander1.
Switch to hypoallergic pillows and bedding1.
Keep your bedroom windows closed to prevent pollen from entering the space2.
Lift your bedhead a few inches to help with nasal congestion2.
Shower before bed to wash allergens away4.
Change your bedding at least once a week4.
Invest in an air purifier/HEPA to filter the air in your bedroom and clean the filter regularly4.
Keeping flowers away from the bedroom.
Avoid drying your bed sheets and clothing outside, as they may catch pollen6.
Treatment for night allergies
There are a few treatment options you can try to help with your night allergies. Examples include:
Saline nasal flushes. Using a device like a Neti pot, you pour a solution into one nostril and let it drain out of the other. This can help to relieve congestion, though the effects often don‘t last long1.
Steroid nasal sprays. These help to stop your immune system from overreacting to allergens, and can help relieve allergy symptoms1.
Antihistamines. A common option used to dry up runny noses and postnasal drips. Be sure to use as instructed1.
Nasal decongestant sprays. Nasal spray decongestants can provide you with long-lasting relief1.

Allergies and sleep: FAQs
Sleep crust, or dust, is a mixture of skin cells, tears and mucus that builds up on your eyelids while you sleep. This is usually completely normal, but in some cases it can indicate an infection or other condition7.
Some studies have shown that lack of sleep can exacerbate allergy symptoms. So, you may find that you become more sensitive to allergy triggers when tired8.
It’s recommended that you consult a doctor if your allergies begin to prevent you from getting the sleep you need, or if the side effects of the medication are negatively impacting you1. Your GP may be able to suggest more suitable treatment options1.
