Asthma

💡 TL;DR: Use your rescue inhaler 10–15 minutes before exercise and warm up for 10 minutes — these two steps prevent most episodes. Quick-relief inhalers protect for about 2–4 hours; if you need them often, a daily inhaled steroid or an ICS/formoterol plan can cut symptoms. Montelukast may

💡 TL;DR: Popcorn lung (bronchiolitis obliterans) scars and narrows the lungs' smallest airways, causing a persistent dry cough and breathlessness that typically begin 2–8 weeks after a big exposure (vape chemicals, toxic fumes, certain illnesses). It is rare but serious and usually doesn’t respond well to quick‑

💡TL;DR: Use your quick-relief inhaler first, then sit upright and breathe slowly; that is the fastest way to calm a night asthma cough. Nights are tougher because of your body clock, lying flat, cool dry air, and bedroom allergens. To prevent wake-ups, take controller meds on schedule, sleep on

💡TL;DR: Most people clear airborne mold spores without illness, but damp homes can trigger allergies or, in at-risk people, aspergillosis (a mold infection). Early signs look like allergies and often improve when you leave the damp space, while serious infection brings high fever, chest pain, weight loss, or blood

💡TL;DR: MDIs spray a measured mist you inhale slowly; DPIs release a dry powder you inhale fast and deep. If timing the press and breath is hard, a DPI can be easier; if you can’t inhale quickly (young children or during a bad flare), an MDI with a

💡TL;DR: Breathe in for 2, out for 4–6 through gently pursed lips to slow your breathing and let trapped air leave. This simple, no-equipment technique can quickly ease shortness of breath by keeping small airways open longer. Use it during activity and at the first sign of breathlessness

💡TL;DR: Most healthy adults keep oxygen saturation around 95–100% during sleep, with only small dips. Brief drops into 90–94% can be normal, but levels that stay below 90% suggest a breathing problem and need a doctor's review. ≤88% for several minutes is dangerous and warrants

💡 TL;DR: Yes, you can have RSV and pneumonia at the same time. RSV can cause viral pneumonia within a few days (often around days 3 to 5), or set up a secondary bacterial pneumonia. Highest risk: infants, adults 65+, and people with lung or immune problems. Expect supportive care

💡TL;DR: Most of the time, the answer is no: a nebulizer without medicine will not treat your lungs; you are just inhaling moist air. The only common exception is sterile 0.9% saline, which can add moisture and thin mucus, but it does not open airways or stop an
