The average cough, typically due to a cold or other respiratory virus, lasts three weeks or less. A lingering or chronic cough lasts eight weeks or longer. Most causes of chronic cough aren't serious, such as bronchitis, seasonal allergies, or medication side effects. People should see a doctor if over-the-counter treatments haven't worked or if they experience signs such as breathlessness, wheezing, chest pain, blood in the sputum, weight loss, or fatigue. Before an appointment, people should track their cough and note its patterns to offer clues for diagnosis.

Sometimes mucus secretions in the lungs can persist after someone starts to get better from a chest cold, flu, pneumonia, or COVID. To cope with the problem, experts recommend two approaches. One is doing exercises that clear the lungs, such as a series of breaths and coughs that dislodges mucus. The other approach is doing exercises that strengthen respiratory muscles. An example is diaphragmatic breathing, a type of deep breathing that relies on the diaphragm muscle located below the lungs.

While cigarette smoking remains the biggest cause of lung cancer, between 15% and 25% of cases globally occur in people who have never smoked. Lung cancer claims more women's lives than breast and ovarian cancer combined. Risk factors among nonsmokers include age, family history, chronic lung conditions, and exposure to secondhand tobacco smoke, radon, diesel fumes, air pollution, and asbestos. People concerned about their risks should discuss it with their doctor, reduce exposure to lung cancer contributors, and get involved in advocacy efforts.

With climate change, rising temperatures are making many regions dry within the US and beyond. The effects of droughts on the planet and our health are complex, and include water shortages, higher risk of disease, changes in habitability, and worse air quality.

New research suggests that people who are hospitalized in an intensive care unit are far less likely to develop pneumonia if their teeth are brushed twice daily. They also need ventilators for less time, are able to leave the ICU more quickly, and are less likely to die in the ICU.

Until recently, many people with asthma used a medicine called Flovent. It has been discontinued by its manufacturer, leaving users with questions about what to substitute and which medicines their insurance will cover.
