Asthma and Secondhand Smoke
Inhaling any irritant is sure to provoke your asthma symptoms, but secondhand smoke is particularly bothersome: with 7,000 substances and 70 known cancer-causing compounds, there’s a lot in there to irritate your airways, bronchial tubes, and deeper regions of the lungs.
While you may find it relatively easy to avoid cold air, high-pollen counts, and other allergic asthma triggers, secondhand smoke tends to fly under the radar. It’s a sneaky trigger, in that it travels farther than you might imagine, and could lurk in a variety of spaces.
Learn why secondhand smoke is so problematic for children and adults with asthma, and take some tips to sidestep the danger altogether.
How Secondhand Smoke Interferes With Breathing
Cigarette smoking tops the list of asthma triggers, but even when not inhaled directly from a cigarette, tobacco smoke can inflame your asthma by:
- Triggering asthma attacks
- Increasing the severity of asthma attacks
- Increasing the risk of developing asthma
Not surprisingly, smoke irritates the already sensitive airways of asthma patients, causing the tissue to swell and the muscle around the bronchial tubes to contract. In both cases, less air will be able to reach the lungs.
Who Suffers Most
Secondhand smoke is clearly bad for everyone, but some people are bound to feel the effects more than others. If your asthma is severe, you may need less of the irritant to suffer uncomfortable breathing problems; a big waft of smoke can have disastrous consequences. However, secondhand smoke can irritate young lungs even more, for a few reasons:
- Children have smaller bodies, and breathe more rapidly than adults. In turn, they will take in more smoke with each breath, and that will leave a higher concentration of carcinogens and toxins in their little lungs.
- Lungs continue to develop throughout childhood, even into the teenage years. Secondhand smoke may stunt lung development in children, leading to less lung volume and worsening respiratory illnesses.
- Children have almost no control of their home environments. If a person chooses to smoke inside the home, children aren’t able to escape the smoke by opening windows or leaving the building – they have no choice but to breathe in the smoky air.
Studies are clear on the consequences for children: kids who breathe in secondhand smoke are not only more likely to develop asthma, but they’re prone to more frequent and severe asthma attacks. Serious infections of the ear, throat, and lungs are another major area of concern, especially for children under 18 months who are regularly exposed to secondhand smoke.
