Study: Asthma inhalers worsen climate; self-powered luggage scale
Breathing Easier While Traveling: What a New Inhaler Study Means for Asthma and COPD Travelers—and How a Battery‑Free Luggage Scale Fits In Travel is supposed to expand your world, not tighten your chest. Yet for millions who live with asthma or COPD, every trip involves a quiet calculus: Will the air be clean? Will my medications pass airport security? Will I make it through the day without a flare? A new environmental study adds another dimension to that planning. It finds that common inhalers contribute to climate change—largely because of the propellants used in metered‑dose devices. The irony isn’t lost on researchers: “These emissions drive global warming, exacerbating the very respiratory conditions inhalers are meant to relieve,” they wrote.
