Do you often have respiratory allergies, but at night, they tend to get worse? Find out why they intensify at night and how to improve your sleep despite the symptoms.
What is a Respiratory Allergy?
Allergy is an inappropriate immune reaction against foreign substances called allergens. As Inserm describes it is a “disruption of the immune system which corresponds to a loss of tolerance towards seemingly harmless substances: allergens”. Allergies can have cutaneous (urticaria, dermatitis), respiratory (rhinitis, asthma) or generalized (anaphylaxis) manifestations.
Respiratory allergy is often linked to inhaling certain allergens in our air. In spring and summer, the famous pollens are responsible for allergic rhinitis. In winter, when we spend more time indoors, pollution in our homes, caused by lack of ventilation, tobacco, dust mites, animal hair, mould, cleaning products and cosmetics, plants or even combustion gases, can irritate the respiratory tract and cause allergies.
Why are allergies worse in the evening or night?
Have you ever noticed that during the night, your allergy symptoms worsen or even trigger respiratory problems or asthma attacks? It’s normal. Respiratory disorders (asthma, allergies, etc.) and sleep disorders are conditions that often coexist.
Circadian Rhythm
“Sleep disorders, including sleep apnea, are often linked to nocturnal respiratory disturbances, sometimes associated with asthma attacks or a blocked nose due to allergic rhinitis,” explains Dr Madiha Ellaffi, pneumoallergist in an article published on the website of the Asthma & Allergies association.
Other mechanisms reinforce this relationship between allergy and sleep. ” Circadian rhythms (which punctuate the waking and sleeping phases) influence allergies and sleep. For example, a lack of sleep can accentuate an inflammatory reaction directly impacting the regulation of immune reactions.”
Acarians
“Finally, other parameters can also come into play, such as bedding,.” “Dust mites love humidity and heat and appreciate bedding as much as they find food there. When an allergic patient falls asleep in a bed with dust mites, the allergic reaction will increase symptoms, including nasal obstruction and difficulty breathing at night.
What are the symptoms of respiratory allergy?
The symptoms are diverse: nasal obstruction, often clear nasal discharge, allergic conjunctivitis with watery eyes and sensation of a “grain of sand” in the eye, itching in the throat and nose, sneezing but also sometimes one of the respiratory symptoms when allergens reach your lungs:
- Difficulty breathing
- Wheezing
Even asthma attacks, in some cases
Regardless of the severity of the symptoms, it is often impossible to get any shut-eye and get proper rest at night. Fortunately, there are solutions to increase your chances of sleeping well.
How to breathe better at night when you have an allergy?
- First, treat your allergy. Once a healthcare professional has made the diagnosis, follow their advice and the treatment they have prescribed for you.
- Cough, scratchy throat, itching, wheezing… what to do?
- Treatment with oral antihistamines may be prescribed to relieve allergic symptoms. If medications cause drowsiness, take them before going to bed. It is also possible to achieve desensitization to the allergen.
- If you have a blocked nose
- Before bed, rinse your nose with a nasal spray to remove allergens from your airways. If you are in the middle of pollen season, wash your hair to remove the residue on your head.
- If you have symptoms of allergic asthma
- If you are prone to allergic asthma, learn the right actions if an attack is triggered. Especially since in people with asthma, asthma attacks most often occur in the evening or at night. Always have your rescue inhaler with you.
How to limit allergens in the bedroom?
Remember to clean your room frequently by vacuuming every little corner and washing sheets and curtains to prevent allergens from accumulating.
- Try to choose anti-allergen bedding if you can.
- Swap chemical cleaning products for natural, fragrance-free versions, such as baking soda or black soap, to clean the room.
- Try to find the right humidity level for your bedroom. Ventilate every day by opening your windows wide for at least 10 minutes. If the air is too dry, you can use a humidifier. Be careful not to overdo it to avoid mould formation. An air purifier can help reduce the harmful effects of dust and pollen.
