Why are allergy symptoms worse in the morning?

The allergies which occur as a result of breathing of agents that the body does not tolerate, they can lead to various annoying events such as stuffy or runny nose, continuous sneezing, coughing, watery eyes and much more.

When they occur, they do so throughout the day but sometimes it can happen that the symptoms are more acute in the morning.

Symptoms affecting the airways are sometimes due to allergic rhinitisee occur when the immune system overreacts to those present in the air.

Agents responsible for morning allergies

The responsible allergens of an exacerbation of allergies in the morning hours are the following.


If you have an allergy to pollen you are likely to notice worsening allergy symptoms in the morning because their concentration in the air is at its highest at that time of dayto. Those suffering from this allergy should therefore, if possible, avoid being outdoors in the morning and in particular stopping in green areas.

Dust mites

Allergies can flare up more in the morning even if you are allergic to dust mites. These insects microscopic are present in homes and the bedroom is their favorite environment since they tend to live and multiply mainly on mattresses, pillows, sheets and furniture.

Dust mites do not bite or spread disease but if you sleep in a bed in which they are present, it is possible to wake up in the morning victims of a major allergic attack.

Pet hair

Pet dander is another morning allergy trigger, especially if your four-legged friend sleeps on the bed or in the same room. In this case, although the allergic attacks may be greater in the morning, they usually persist during the day since even when pets are not sleeping with their owner, their hair can still accumulate in other areas of the house.


Mold can also worsen allergy symptoms in the morning hours, particularly if the bedroom where you rest is in the immediate vicinity of a bathroom or in another place where concentration is important.

Other causes of allergy symptoms in the morning

Nasal congestion, coughing and sneezing can also do not depend on allergens but be symptoms of non-allergic rhinitis which, unlike allergic rhinitis, does not involve the immune system.

Strong smells

Sleeping on your back can make this condition worse and irritate your throat, leading to as a result to pain in the area, nasal drip and cough in the morning. In this case, however, the symptoms often improve over the course of the day.

Hormonal changes

Pregnancy, menstruation or use of oral contraceptives can also cause non-allergic rhinitis because hormonal swings that characterize these events they often increase mucus production and trigger changes in the mucous membrane, resulting in nasal congestion, runny nose, and sneezing.

Hormonal changes cause allergy-like symptoms throughout the day but are usually more intense in the morning.
