Asthma is a long-term condition that can make breathing difficult when airways become swollen, tight, or filled with mucus. This cheat sheet helps students recognize common triggers, early warning signs, and safe ways to manage symptoms. It is useful for school, sports, home, and other places where quick decisions can protect health.
Students need clear steps so they know when to avoid triggers, use medicine, or get help.
Key Facts
- Common asthma triggers include smoke, dust, pollen, mold, pet dander, cold air, exercise, strong smells, respiratory infections, and air pollution.
- Early asthma warning signs can include coughing, wheezing, chest tightness, shortness of breath, tiredness, or trouble speaking in full sentences.
- A quick-relief inhaler is used for fast symptom relief during an asthma flare, but it does not replace daily controller medicine if a doctor prescribed one.
- Controller medicine is taken as prescribed to reduce airway swelling over time, even when the person feels well.
- An asthma action plan usually has green, yellow, and red zones that explain daily care, worsening symptoms, and emergency steps.
- If symptoms are severe, if lips or fingernails look blue or gray, or if breathing is very hard, call emergency services right away.
- Using a spacer with a metered-dose inhaler can help more medicine reach the lungs instead of staying in the mouth or throat.
- Students with asthma should tell trusted adults where their inhaler is and what steps are listed in their asthma action plan.
Vocabulary
- Asthma
- A health condition where the airways can become swollen and narrow, making it harder to breathe.
- Trigger
- Something that can start or worsen asthma symptoms, such as smoke, pollen, exercise, or cold air.
- Quick-relief inhaler
- A medicine device used to relax airway muscles and help breathing during asthma symptoms or an attack.
- Controller medicine
- Medicine taken regularly to prevent inflammation and reduce the chance of asthma flare-ups.
- Spacer
- A tube or chamber attached to an inhaler that helps deliver medicine more effectively into the lungs.
- Asthma action plan
- A written plan from a healthcare provider that explains daily care, symptom zones, medicine use, and emergency steps.
Common Mistakes to Avoid
- Ignoring early symptoms is dangerous because mild coughing or chest tightness can become a serious asthma flare if not managed quickly.
- Using someone else’s inhaler is unsafe because asthma medicine and doses are prescribed for a specific person and situation.
- Stopping controller medicine when feeling well is wrong because controller medicine helps prevent airway swelling before symptoms begin.
- Staying near a known trigger is risky because continued exposure to smoke, dust, pets, or cold air can make symptoms worse.
- Waiting too long to tell an adult is unsafe because severe breathing trouble needs fast help, especially if speaking or walking becomes difficult.
Practice Questions

- 2 A class has 28 students, and 7 report that pollen can trigger their asthma symptoms. What fraction and percent of the class reported pollen as a trigger?
- 3 During gym, a student feels chest tightness after running for 6 minutes and rests for 4 minutes. How many total minutes passed from the start of running to the end of resting?
- 4 Why is it important for a student with asthma to know both personal triggers and the steps in an asthma action plan?
