With the ongoing COVID-19 pandemic and approaching winter season, lung health is more important than ever. Here are five ways to exercise and improve lung health, as recommended by Dr. Luis Javier Peña-Hernández, a lung health specialist in Florida. 1. Homemade masks should be cleaned frequently to prevent bacteria buildup. According to the CDC, masks can be cleaned along with your laundry or washed by hand with diluted bleach. 2. Not only does exercise keep your body in shape, it keeps your lungs in shape too. .With consistent exercise, lungs can achieve improved capacity, aka easier breathing. 3. Singing during a hot shower might seem silly, but it benefits your lungs in two big ways. .Steam naturally loosens mucus in your throat and lungs, and singing can help by naturally clearing that mucus out. .4. Reduce your exposure to indoor and outdoor pollutants to take the burden off your lungs.This includes smoke, vehicle exhaust, dust, fumes from cleaning products and artificially-scented candles. 5. Regularly practice breathing exercises such as pursed lip breathing and diaphragmatic breathing. .These will help increase your oxygen levels and strengthen the elasticity of your diaphragm.
