Effects of Menthol on Dyspnoea in COPD Patients
Effects of Menthol on Dyspnoea in COPD Patients
Chronic obstructive pulmonary disease (COPD) is characterised by non-reversible bronchial
 obstruction associated with systemic disorders and comorbid factors. Dyspnoea is a common
 symptom among patients with Chronic Obstructive pulmonary Disease (COPD). Dyspnea is the
 primary symptom limiting exercise and daily activities in these patients. It has been
 reported that breathing cold air could decrease dyspnoea induced by exercise and could
 improve exercise performance. The aim of this study is to carry out the effect of cooling
 sensation induced by menthol chewing-gum on dyspnoea and exercise performance among patients
 with COPD.
