💡TL;DR: Obstructive sleep apnea can run in families: having a first-degree relative with OSA is linked to about a 50% higher risk. Central sleep apnea is usually not inherited. Genetics explain roughly 40% of apnea severity, while weight, airway anatomy, alcohol, age, and other factors explain the rest. Practical

💡TL;DR: Asthma is not an autoimmune disease; it’s a chronic inflammatory airway condition where the immune system overreacts to external triggers (like pollen, dust, smoke, or cold air). In autoimmunity, the immune system attacks the body’s own tissues, which is not what happens in asthma. Treatments differ:

What Is a Portable Oxygen Concentrator and Who Needs One? A portable oxygen concentrator (POC) is a small, battery-powered medical device that pulls in room air, concentrates the oxygen, and sends it to you through a nasal cannula. Unlike oxygen tanks, POCs don’t store oxygen. They make it on

💡TL;DR: Yes — you can bring an asthma inhaler on a plane in both carry-on and checked bags; TSA classifies inhalers as medically necessary and exempts them from the 3-1-1 liquids rule. For a smooth trip, keep it in your carry-on for quick access and temperature control, and bring a

💡TL;DR: Hot cars can reach 140–160°F (60–71°C), far above safe storage for inhalers. Pressurized MDIs can weaken or even burst around ~120°F (49°C); all inhaler types work best at 68–77°F (20–25°C). If an inhaler overheats, treat it as unreliable

💡TL;DR: No — do not leave inhalers in a cold car. Most inhalers are designed for room temperature 59–86°F (15–30°C); at ≤32°F (0°C) the spray can be weak or fail. If it was briefly above freezing, let it warm to room temperature and release

💡TL;DR: Clean pressurized metered‑dose inhalers once a week: remove the metal canister, rinse the plastic mouthpiece under warm water for 30–60 seconds, and air‑dry completely before reassembly. Dry powder inhalers should not be rinsed; wipe the mouthpiece dry and keep the device closed between uses. Soft‑

💡TL;DR: Prime new metered-dose inhalers (MDIs) with 2–4 test sprays and re-prime after about 1–2 weeks of no use or if dropped so the first dose contains medication. Skipping priming can make the first puff mostly propellant with little or no medicine. Dry powder inhalers (Diskus, Ellipta)

💡TL;DR: Yes—pneumonia can cause back pain when inflamed lung linings (pleurisy) make each deep breath or cough painful. The pain is usually sharp in the upper or mid‑back and occurs with cough, fever, and shortness of breath. About 1 million U.S. adults are hospitalized for pneumonia
