How to Sleep Better With Allergies: A Bedroom and Bedtime Checklist

Allergies and sleep don’t mix well. The American College of Allergy, Asthma and Immunology (ACAAI) lists fatigue, often from poor sleep caused by a blocked nose, as a symptom of hay fever, and sleep disorders as one of its complications. Dust mite symptoms are often worse at night, and more than two-thirds of people with asthma have symptoms that worsen at night.

The good news: your bedroom is the easiest room to control. This checklist covers allergen-proofing the bedroom, a bedtime routine, and how to time allergy medicines so they help rather than keep you up. For more, see our dust mite and bedding guides.

Quick answer

• Encase and wash: allergen-proof covers on the mattress, box spring and pillows, and weekly washes of bedding in water of at least 130°F (54.4°C) (Mayo Clinic).
• Dry, closed and filtered: keep humidity below 50%, windows closed during pollen season, and consider a HEPA filter in the bedroom.
• Keep pets out of the bedroom so you’re not breathing their allergens all night (ACAAI).
• Rinse off pollen with a shower and clean clothes before bed.
• Choose medicines carefully: older antihistamines can make you drowsy the next day, and decongestants taken late can cause insomnia (ACAAI).

Why allergies are often worse at night

• You’re lying in your allergens. Mayo Clinic notes dust mite symptoms are often worse while sleeping, since mites live in bedding, upholstered furniture and carpet.
• A blocked nose disrupts sleep. ACAAI links hay fever fatigue to poor-quality sleep from nasal obstruction.
• Asthma follows a daily rhythm. A 2018 systematic review notes that nighttime worsening affects more than two-thirds of people with asthma. The causes aren’t fully understood, but daily changes in lung function and lying flat both contribute.
• Pollen comes in with you. Pollen on hair, skin and clothes ends up on your pillow if you don’t wash it off.

Make your bedroom allergy-friendly

Steps from Mayo Clinic’s dust mite and hay fever guidance unless noted. Covers work best as part of this whole plan rather than on their own; see mattress and pillow covers for allergies. For laundry details, read does a dryer kill dust mites? and for humidity, humidity control for allergies.

A bedtime routine for allergy season

1. Shower, shampoo and change clothes when you come in from outside, or at least before bed, to rinse off pollen, as the American Academy of Allergy, Asthma and Immunology (AAAAI) recommends.
2. Don’t dry laundry outdoors on high-pollen days, since pollen sticks to sheets and towels (Mayo Clinic).
3. Rinse your nose with saline if it helps you. Use only distilled, sterile or boiled and cooled water; see how to use a neti pot safely.
4. Check tomorrow’s pollen forecast so you can plan medicines and outdoor time. See our pollen avoidance guide.

Allergy medicines and sleep

The right medicine can be the difference between a blocked nose and a full night’s sleep, but some choices backfire. According to the ACAAI:

• Nasal steroid sprays are the single most effective drug class for allergic rhinitis, including congestion.
• Newer (second-generation) antihistamines generally work well with only minor side effects.
• Older (first-generation) antihistamines, the kind often found in nighttime cold and allergy products, can cause drowsiness and impair performance, even the next day when taken only at bedtime.
• Oral decongestants commonly cause insomnia when taken in the afternoon or evening. People with high blood pressure or heart disease should check with their doctor first.
• Decongestant nasal sprays shouldn’t be used for more than a few days at a time unless your doctor says so, because they can cause rebound swelling.

For more on combination products, see Claritin-D, Theraflu and what’s behind the counter. If your child’s symptoms flare at night, read why kids’ allergies get worse at night.

When to see a doctor

• You wake up coughing, wheezing or short of breath, which can be a sign of asthma.
• You snore loudly or feel tired despite a full night in bed.
• Over-the-counter medicines and bedroom changes haven’t helped after a few weeks.

An allergist can test what you’re reacting to and talk about longer-term options like allergy tablets or shots.

Frequently asked questions

Why are my allergies worse at night?

You’re surrounded by bedding allergens like dust mites, pollen from the day may be on your hair and pillow, and a blocked nose disrupts sleep. Asthma also tends to worsen at night for many people.

What’s the best allergy medicine for sleep?

Ask your doctor. ACAAI says nasal steroid sprays are the most effective drug class for allergic rhinitis and newer antihistamines have only minor side effects, while older antihistamines can impair you the next day and decongestants can cause insomnia if taken late.

Does an air purifier in the bedroom help allergies?

Mayo Clinic suggests a HEPA filter in the bedroom as part of hay fever self-care. It works best combined with closed windows, washed bedding and humidity control.

Should I shower before bed during allergy season?

Yes. AAAAI recommends showering, shampooing and changing clothes after being outdoors to remove pollen.

Should pets sleep in the bedroom if I’m allergic?

No. ACAAI advises keeping pets out of the bedroom so you aren’t exposed to their allergens while you sleep.
