Why Are Allergies Worse At Night? Causes And Relief
If you feel that your allergy symptoms are getting worse while you are trying to sleep, it is not just you. Many people in the UK experience worsening symptoms like sneezing, itchy eyes, as well as congestion at night. There are various reasons for this - the allergens in your indoor environment or your body’s response while lying down can trigger this.
Common nighttime allergens include dust mites, pollen, and pet dander, which get stuck to pillows and other parts of the bed. They worsen your cough or nasal congestion and disrupt sleep, leading to reduced immunity, tiredness, or decline in your overall health. This blog will help you know how to reduce nighttime allergy symptoms. Let’s scroll!
Common Causes of Nighttime Allergies
The most common causes of nighttime allergies are:
1. Pollen Exposure From the Day
Concerning reasons for nighttime allergies are pollen that sticks to people’s clothing, hair, and skin. All of these allergens are likely to aggravate allergy symptoms when they rub off onto your bedding while asleep. Showering before bedtime gets rid of the lingering pollen, and closing the windows reduces the exposure of pollen getting in while you are asleep.
2. Dust Mites and Indoor Allergens
Mattresses, pillows, and bedding are a common hiding place for dust mites, which are a major cause of nighttime allergies. Their microscopic waste can make you sneeze, have a runny or blocked nose, and cause itchy eyes while sleeping. To avoid exposure and reduce indoor allergens, hypoallergenic protective covers for pillows and mattresses, hot water washing of bedding weekly, and vacuuming are recommended.
3. Pet Allergies
Pet allergies are often triggered by dander that gets lodged in carpets, bedding, and the bedroom. If pets are not present, their allergens can linger in the air and on surfaces. So, refrain from bringing pets to the bedroom and wash bedding regularly to sleep better and reduce exposure. Frequent vacuuming and using air purifiers also aid in preventing dander accumulation.
4. Postnasal Drip and Sleeping Position
During postnasal drip, the mucus accumulates at the back of the throat, especially when lying down. This buildup worsens throat irritation, coughing, and congestion during sleep. Sleeping with the head elevated enhances the proper drainage of mucus, alleviating symptoms, and promoting easy breathing through the night. Correct sleeping posture can also relieve allergy symptoms significantly.
5. Mould and Dampness
Allergies triggered by mould and dampness are often hidden. Mould is one of the most common triggers, and it can thrive in humid places like bathrooms and basements. Mould spores can build up in the air due to poor ventilation, triggering allergic reactions while you sleep. Control the humidity level to stop these spores from flourishing in moist conditions. Improve airflow and use dehumidifiers to reduce mold growth and ease allergy symptoms.
6. Irritants and Air Quality
Indoor pollutants such as smoke and artificial fragrances affect air quality and trigger allergy symptoms. Poor air circulation traps dust, mold, and other chemical irritants in the bedroom. Use a high-efficiency air purifier, avoid scented candles or sprays, and ventilate your room regularly to improve air quality. Also, choose fragrance-free cleaning products and keep indoor plants to make a big difference.
How to Reduce Nighttime Allergy Symptoms
You can reduce nighttime allergy symptoms by:
- Using preventative coverings (allergy-proof bedding) to limit exposure to dust mites.
- Showering before sleep to remove pollen and allergens.
- Improving air quality and filtering allergens via air purifiers
- Keeping pets out of your bedroom to limit hair and dander buildup
- Maintaining good ventilation to avoid dust and mold accumulation
- Taking antihistamines or nasal sprays for symptom relief (only after consulting a pharmacist)
When to Consult a Doctor
You must consult your doctor if:
- Your allergy symptoms are severe, persistent, or interfering with sleeping or day-to-day activities.
- Over-the-counter treatments are not offering enough relief
- You need allergy testing to identify specific triggers or prescription medications.
- You want a tailored or more targeted treatment plan.
Let’s Wrap Up!
Night-time allergies are exacerbated by common factors such as low indoor air quality, exposure to dust, dust mites, pet hair, pollen, and lingering indoor pollutants. Even habits like using scented products or closing the windows without proper ventilation can trigger allergic reactions.
Knowing what the common triggers are, and what simple preventive measures can be taken, such as using allergen-proof pillows and mattresses, running an air purifier, restricting pets from the bedroom, and controlling symptoms with the right medications, can help improve sleep and feeling refreshed after waking up. In managing nighttime allergies, implementing and integrating a few simple changes into your routine can dramatically improve the overall quality of life.
