Struggling to Breathe: Respiratory Issues After Cleaning with Bleach - Pulmonology

Share to:

Breathing requires significant effort to intake air?


Hello, doctor: Recently, I have been experiencing a sensation of needing to exert a lot of effort to breathe, which started after using undiluted bleach for cleaning.
After feeling unwell while scrubbing the toilet, I quickly opened a window and left the area for about five minutes.
This condition has persisted for four days now.
Besides the effortful breathing and chest tightness, I have not experienced any coughing or pain.
However, I do have a history of autonomic nervous system dysregulation and anxiety.
I am unsure which aspect may be causing this, as I felt very anxious and rushed outside to take deep breaths when I first felt uncomfortable while using the bleach.
Additionally, I also have gastroesophageal reflux disease (GERD).
I would like to ask: Could using undiluted bleach in a closed space for a short period cause serious damage to my lungs or respiratory tract? The difficulty in breathing sometimes suddenly improves but then quickly returns.

Hello: The intermittent symptoms should not indicate any significant damage to the trachea or lungs; with some time for adjustment, it should improve! For autonomic nervous system dysregulation and anxiety disorders, it is recommended to have regular follow-ups at a psychosomatic medicine clinic.

More Info


Using bleach and other strong cleaning agents without proper ventilation can indeed lead to respiratory issues, especially if they are not diluted. Bleach contains sodium hypochlorite, which can release chlorine gas when mixed with other substances or when used in high concentrations. Inhaling chlorine gas can irritate the respiratory tract, leading to symptoms such as difficulty breathing, chest tightness, and a feeling of breathlessness.
Given your description of struggling to breathe and experiencing chest tightness for four days after using bleach, it is essential to consider a few factors. First, the acute exposure to bleach may have caused irritation to your airways, leading to inflammation and a temporary decrease in lung function. This can manifest as a sensation of needing to exert more effort to breathe, which can be exacerbated by anxiety. Anxiety can create a feedback loop where the fear of not being able to breathe leads to hyperventilation, which can further exacerbate feelings of breathlessness.

In your case, the combination of your existing conditions—autonomic nervous system dysregulation and gastroesophageal reflux disease (GERD)—may also contribute to your symptoms. GERD can cause acid to flow back into the esophagus, which can lead to irritation of the throat and even mimic respiratory issues. The stress and anxiety from your breathing difficulties can also trigger or worsen GERD symptoms, creating a cycle of discomfort.

To address your concerns, here are some recommendations:
1. Ventilation: Always ensure that you are in a well-ventilated area when using bleach or other strong cleaning agents. Open windows and doors to allow fresh air to circulate, and consider using fans to help disperse fumes.

2. Dilution: When using bleach, always dilute it according to the manufacturer's instructions. This reduces the concentration of harmful fumes and minimizes the risk of respiratory irritation.

3. Breathing Techniques: Practice deep breathing exercises to help manage anxiety and improve your breathing. Techniques such as diaphragmatic breathing can help you take deeper, more effective breaths.

4. Avoid Triggers: If you notice that certain activities or substances exacerbate your symptoms, try to avoid them. This includes strong cleaning agents, smoke, or other irritants.

5. Medical Evaluation: Since your symptoms have persisted for several days, it would be prudent to consult a healthcare professional. They may recommend a pulmonary function test to assess your lung capacity and function. If necessary, they might also prescribe bronchodilators or corticosteroids to reduce inflammation in your airways.

6. Anxiety Management: Consider seeking support for managing anxiety, whether through therapy, mindfulness practices, or relaxation techniques. Reducing anxiety can help alleviate some of the respiratory symptoms you are experiencing.

7. Follow-up on GERD: If you suspect that your GERD is contributing to your symptoms, discuss this with your healthcare provider. They may recommend dietary changes, medications, or other interventions to help manage your reflux.

In summary, while short-term exposure to undiluted bleach can cause respiratory irritation, the symptoms you are experiencing may also be influenced by anxiety and pre-existing conditions. Taking preventive measures, practicing breathing techniques, and consulting with a healthcare professional will be essential steps in addressing your concerns and improving your respiratory health.
