Introduction

In the February 25, 2025 episode of Brains On!, host Molly Bloom teams up with co-hosts Audrey and Indy from Queensland, Australia, to delve into the topic of asthma. The episode aims to educate young listeners and their families about asthma, its causes, symptoms, and treatments through engaging discussions, personal stories, and expert insights.

Personal Experiences with Asthma

Molly Bloom begins by sharing her personal journey with asthma, explaining how she was diagnosed as an adult due to worsening allergies in college. She notes, “[...] now it's pretty much under control. But sometimes when there's lots of pollens or I'm around cats, it still feels hard to breathe” (03:09).

Audrey and Indy also share their experiences:

• Audrey was diagnosed around age four or five and mentions, “I feel like it's gotten a slight bit worse over the years. And smoke, and I have allergies, and laughing too hard when I'm with my friends, like, that can make it worse” (03:29).
• Indy received her diagnosis around the same age and states, “it's mild, but most of the time it gets, like, worse when I'm sick” (04:09).

Both use Ventolin inhalers to manage their symptoms, highlighting the commonality among many with asthma.

Listener Questions

The episode incorporates questions from listeners to address common curiosities about asthma:

• Ruthie from Louisiana asks, “how inhalers work, because I use one every night” (04:35).
• Harper from Moorpark, California inquires, “how do you get asthma?” (04:42).
• Audrey and Indy also pose, “why do some people have asthma and what causes it?” (04:50).

These questions set the stage for a deeper exploration of asthma’s mechanics and causes.

Understanding How Breathing Works

To provide a foundational understanding, Molly refers to a previous episode on breathing and outlines the basics: “When you breathe in, the air goes through the nose or mouth into the windpipe, which splits into two bronchi leading to the lungs” (05:23). Audrey suggests a visual demonstration, leading to an imaginative journey inside the lungs with the help of a creative skit featuring Joy Dolo.

Asthma Mechanism: How Asthma Affects the Bronchi

Inside the lungs, Molly explains, “When someone has an asthma attack, these bronchi can swell up and the muscles around them can tighten, which makes it hard to breathe” (07:50). Audrey adds, “Narrower enough to make breathing really difficult. When this happens, it’s often called an asthma attack” (08:06).

They discuss triggers such as exercise, illnesses, allergies, and stress, emphasizing how these factors cause inflammation and muscle constriction in the airways.

Personal Accounts of Asthma Attacks

Audrey and Indy recount their experiences during asthma attacks:

• Indy recalls a cold snap in Japan that made breathing difficult, prompting the use of her inhaler (09:21).
• Audrey shares a less severe attack during Easter at the Gold Coast, where a hot shower and coffee helped alleviate her symptoms (09:32).

Molly reflects on a similar experience: “One time I had an asthma attack when I was at my friend's house who had a cat. It felt like I just couldn't get a deep breath” (08:49).

Rescue Inhalers and Treatment

The conversation transitions to the functionality of rescue inhalers: “When that happens, using a rescue inhaler can help” (16:46). Audrey explains, “You push down on the canister to release a spray of medicine that you breathe in” (17:01). This segment highlights the importance of inhalers in managing acute asthma symptoms.

Expert Insight: Interview with Dr. Stephanie Levinsky

To provide authoritative information, Dr. Stephanie Levinsky, a pediatric pulmonologist, joins the discussion. Key insights from her interview include:

• How Rescue Inhalers Work:

  “When you take your rescue pump, what that medication does is it relaxes those muscles to open up the airway so they're not squeezed so tight” (17:26).

• Causes of Asthma:

  “People whose parents or their siblings have asthma are more likely to have asthma. There might be some genetic components... environmental air pollution might trigger the lungs to be more sensitive” (20:33).

• Diagnosis of Asthma:

  “Doctors ask questions about symptoms, perform physical exams, and conduct breathing tests to determine if someone has asthma” (19:05).

• Evolution of Treatment:

  “There are new medications, including injections that quiet down the immune system, making it less reactive to environmental triggers” (21:29).

• Genetic and Environmental Factors:

  “Asthma is influenced by both genetics and environmental exposures, such as living in polluted areas” (20:33).

• Advice for Kids with Asthma:

  “Asthma's pretty common. Many athletes have asthma, and they're still able to be highly functioning and very active. Asthma should not get in the way of having a super active life” (22:27).

Dr. Levinsky also shares her personal motivation for becoming a pulmonologist, stemming from her own experiences with asthma as a child.

Mystery Sound Segment

Interspersed throughout the episode is an interactive segment where listeners guess a mystery sound. In this episode, Molly plays the sound of someone washing hands with soap, challenging the co-hosts and listeners to identify it:

“That was the sound of me washing my hands with soap. Washing hands with soap” (25:27).

Conclusion

The episode wraps up with a recap of asthma’s impact, available treatments, and ongoing research to better understand and manage the condition. Molly encourages listeners to stay curious and continue exploring scientific topics through future episodes.

Notable Quotes:

• Molly Bloom on asthma’s impact:

  “Asthma is a disease that can make it hard to breathe” (23:00).

• Dr. Levinsky on overcoming asthma challenges:

  “Asthma should not get in the way of having a super active life” (22:27).

Key Takeaways:

• Asthma involves the swelling and tightening of the bronchi, making breathing difficult.
• Triggers include exercise, allergens, illnesses, and stress.
• Rescue inhalers are crucial for managing acute asthma symptoms by relaxing airway muscles.
• Genetics and environmental factors both play significant roles in the development of asthma.
• Ongoing research is improving asthma treatments, including new medications and injections.
• With proper management, individuals with asthma can lead active, fulfilling lives.
