Autumn Cooling Has Its Rules When the Weather Turns Cool
In early autumn, summer heat lingers, temperatures remain high—so "cooling down" is harmless and no need to rush to add clothes. In mid-autumn, temperatures begin to drop, though cool, not severely cold—this is the optimal period for "autumn cooling," especially for young and middle-aged adults. Wear clothing with controlled layering, intentionally allowing the body to experience mild cold to avoid overheating and sweating, which would deplete yin and consume qi. In late autumn, weather changes drastically, with increased day-night temperature differences. Especially during the transition from autumn to winter, strong cold fronts often bring sudden drops in temperature. At this time, persistently insisting on "autumn cooling" would be counterproductive.
Due to geographical differences, southern and northern China vary in climate. Generally, southern regions experience cooler weather later, with small diurnal temperature variations. Even in winter, it may not be very cold, so there is no need to add clothes too quickly, and "autumn cooling" can be extended. Northern regions differ—cold can arrive suddenly, with large daytime temperature swings. Thus, blindly pursuing "cooling" is unwise, risking exposure to wind-cold.
From a human perspective, children are delicate in yin and yang, still developing, with poor self-regulation. Cold stimuli quickly trigger adverse reactions, potentially causing acute bronchitis, pneumonia, and other diseases. Elderly individuals have diminished yin and yang, weakened overall resistance, and reduced cold tolerance. Cold stimulation can cause bronchial and vascular spasm and constriction, easily triggering recurrence of chronic bronchitis, asthma, and even angina or myocardial infarction in some coronary heart disease patients, or stroke in hypertensive patients. Therefore, "autumn cooling" for children and the elderly must be approached with great caution!
