What Are The Common Triggers For Asthma Attacks In Children?

Asthma attacks can be frightening for both children and their parents. Understanding the common triggers for asthma attacks in children is crucial in managing their condition and preventing future episodes. In this article, we will explore the various factors that can trigger asthma attacks in children, ranging from allergens such as dust mites and pollen to physical exertion and respiratory infections. By identifying and minimizing these triggers, you can help your child breathe easier and reduce the frequency of asthma attacks.


Dust mites

Dust mites are tiny, insect-like pests that commonly inhabit homes and thrive in warm and humid environments. They can be found in bedding, pillows, carpets, and upholstered furniture. For children with asthma, exposure to dust mites can trigger an asthma attack. It’s crucial to regularly clean and vacuum their living spaces, wash their bedding in hot water, and use allergen-proof covers on mattresses and pillows to reduce the presence of dust mites.


Pollen is a common trigger for asthma attacks, especially during the spring and fall seasons when plants release large amounts of pollen into the air. For children with asthma, inhaling pollen can cause their airways to become inflamed and constricted, leading to difficulty breathing. It’s important to monitor pollen levels and keep children indoors when pollen counts are high, especially during peak times of the day when pollen is most prevalent.

Pet dander

For children who are allergic to pet dander, exposure to animals can worsen their asthma symptoms and trigger an attack. Pet dander refers to the microscopic flakes of skin and saliva that pets shed. Even if a child does not have a pet allergy, some animals with fur can still trigger asthma symptoms due to the allergens they carry, such as dust or pollen. It’s essential to minimize exposure to pet dander by keeping pets out of the child’s bedroom and regularly grooming them to reduce shedding.

Mold spores

Mold spores are tiny particles released by mold that can cause allergic reactions in some individuals, including children with asthma.

Influenza, commonly known as the flu, is a respiratory infection caused by the influenza virus. The flu can have more severe symptoms than the common cold and can lead to complications for children with asthma. In addition to the typical flu symptoms of fever, body aches, and fatigue, children with asthma may experience worsened breathing difficulties and increased risk of asthma attacks. It is highly recommended to get an annual flu vaccine to protect children with asthma from the flu and its potential complications.

Respiratory syncytial virus (RSV)

RSV is a common viral infection that primarily affects infants and young children. It can cause respiratory symptoms similar to a cold, such as coughing, sneezing, and congestion. For children with asthma, RSV can lead to more severe respiratory distress and trigger asthma symptoms. Practicing good hand hygiene, especially during the RSV season, and avoiding close contact with sick individuals can help reduce the risk of RSV infection and subsequent asthma attacks in children.


Strenuous physical activity

While exercise is generally beneficial for overall health, intense physical activity can trigger asthma symptoms in children with exercise-induced asthma (EIA). EIA is a type of asthma that is specifically triggered by exercise. It typically occurs when children engage in activities that require intense exertion or prolonged periods of physical activity. It is essential for children with EIA to take preventive measures, such as using their prescribed inhaler before exercise and discussing an appropriate exercise plan with their healthcare provider, to minimize the risk of asthma attacks during physical activity.

Cold air during exercise

In addition to intense physical activity, exposure to cold air during exercise can also trigger asthma symptoms in some children. Cold air can cause the airways to constrict, making it harder for children with asthma to breathe. Warming up before exercise, covering the mouth and nose with a scarf or mask, and avoiding exercising outdoors during extremely cold weather can help reduce the impact of cold air on asthma symptoms and prevent exercise-induced asthma attacks.

Air Pollution


Exposure to smoke, whether from cigarette smoke or other sources such as wood-burning stoves or bonfires, can act as a potent asthma trigger for children. The particles and chemicals in smoke can irritate the airways, leading to inflammation and asthma symptoms. It is crucial to keep children away from areas where smoking is allowed, refrain from smoking indoors or around children, and limit exposure to smoke-generating activities to reduce the risk of asthma attacks.

Strong odors

Strong odors from perfumes, cleaning products, paints, or chemicals can also trigger asthma symptoms in children. The chemicals in these products can irritate the airways and cause asthma attacks. Using fragrance-free or low-odor products, ensuring proper ventilation when using strong-smelling substances, and avoiding direct exposure to strong odors can help decrease the likelihood of triggering asthma symptoms in children.

Industrial emissions

Living near industrial areas or areas with heavy traffic can expose children to high levels of air pollution, which can worsen asthma symptoms and increase the risk of asthma attacks. Industrial emissions, including pollutants such as sulfur dioxide and nitrogen oxides, can irritate the airways and make it more difficult for children with asthma to breathe. Minimizing outdoor activities on days with poor air quality, using air purifiers at home, and advocating for stricter environmental regulations can help reduce exposure to industrial emissions and protect children with asthma.

Weather Changes

Cold air

Cold air is a common trigger for asthma attacks in children. Breathing in cold air can cause the airways to constrict and trigger asthma symptoms such as wheezing, coughing, and shortness of breath. To minimize the effects of cold air on asthma, children should dress warmly and cover their nose and mouth when outdoors during cold weather. Additionally, maintaining indoor temperatures and humidity levels can help create a more comfortable environment for children with asthma and reduce the risk of asthma attacks.


High humidity levels can also worsen asthma symptoms in children. Increased moisture in the air can promote the growth of mold and dust mites, both of which are common allergens that can trigger asthma attacks. It’s essential to control humidity levels in the home by using dehumidifiers and properly ventilating areas prone to moisture, such as bathrooms and kitchens. Monitoring the humidity levels in your child’s environment and taking necessary measures to reduce humidity can help minimize the risk of asthma attacks related to high humidity.

Sudden temperature changes

Rapid changes in temperature, such as transitioning from a warm indoor environment to cold outdoor air, can trigger asthma symptoms in children. The abrupt shift in temperature can cause the airways to constrict and make it harder to breathe. To mitigate the impact of sudden temperature changes, children should dress appropriately for the weather and allow their bodies to adjust gradually to changing temperatures. Proper layering of clothing and wearing scarves or masks to cover their nose and mouth can help protect children with asthma from the effects of sudden temperature changes.

Secondhand Smoke

Exposure to tobacco smoke

Secondhand smoke, also known as passive smoking, can be highly detrimental to children with asthma. Breathing in the smoke produced by someone else’s tobacco use can trigger asthma attacks and exacerbate asthma symptoms. Secondhand smoke contains numerous harmful chemicals that can irritate the airways and cause inflammation. It is crucial to create a smoke-free environment for children by strictly enforcing no smoking rules in the home and car and avoiding places where smoking is allowed.

Emotional Factors


While emotional factors may not directly trigger an asthma attack, stress can worsen asthma symptoms and increase the sensitivity of the airways. When children with asthma experience stress, their bodies release stress hormones that can lead to inflammation and narrow the airways. It is essential to manage stress levels in children by promoting relaxation techniques, providing emotional support, and creating a calm and supportive environment. By reducing stress, it is possible to alleviate the impact of emotional factors on asthma symptoms and lower the risk of asthma attacks.
