This study looked at whether a 6-week breathing exercise program (inspiratory muscle training) can improve diaphragm strength and reduce shortness of breath in people who had COVID-19 and still feel breathless. 18 adults with confirmed diaphragm weakness participated. The goal wa…

This study looked at how a treatment called nasal high-flow therapy (NHFT) affects breathing and the body's 'fight-or-flight' nerve signals in 30 adults with asthma. Researchers measured heart rate, blood pressure, and nerve activity to see if NHFT changes these patterns. The goa…

This study looked at why some people who were hospitalized for COVID-19 still feel tired and short of breath. Researchers measured breathing muscle strength in 50 survivors—half had been on a ventilator, half had only needed extra oxygen. The goal was to understand how severe COV…

This study looked at whether chewing gum changes FeNO levels—a key breath test used to guide asthma treatment. Thirty adults with asthma chewed a special sugar-free gum for 15 minutes, then had their FeNO measured again. The goal was to see if gum could cause misleading results, …

This study looked at how using a treadmill at a standing desk, combined with cooler room temperatures, affects back health, blood sugar, thinking, and comfort. Sixteen healthy adults spent four days in a lab office, alternating between sitting and light walking at either 19°C or …

This study looked at whether weakness in the diaphragm, a key breathing muscle, causes ongoing shortness of breath and fatigue in people who had COVID-19 but were not hospitalized. Researchers measured breathing muscle strength and used ultrasound to check diaphragm function in 2…
