Regarding the seasonal issue of pneumothorax recurrence, the causes of pneumothorax vary among patients of different ages, so the seasons prone to recurrence are also not exactly the same. For young patients, pneumothorax tends to recur easily, often in thin and tall patients, usually related to recent colds and coughs, or intense physical activities like basketball, soccer, or seasons with more outdoor activities; these times are relatively more prone to recurrence. Particularly, the cooler seasons of spring and fall are also prone to recurrences. However, for elderly patients, the causes of pneumothorax recurrence are usually associated with smoking in older patients, or a history of chronic obstructive pulmonary disease and bullae. For these elderly patients, recurrences typically occur in the autumn and winter seasons. This is because the autumn and winter seasons are comparatively more problematic for patients with chronic bronchitis and obstructive lung diseases. Thus, pneumothorax recurrence in young people often happens more in the spring and autumn, while in older people, it occurs more in the autumn and winter seasons.
