Understanding Cold Dew: The Transition to Late Autumn
Summary:
- Cold Dew signifies the end of autumn and the onset of winter, characterized by a drop in temperatures and environmental changes.
- This solar term emphasizes health preservation, focusing on moistening the lungs and stomach to counteract dryness.
- Traditional customs during Cold Dew include mountain climbing, red leaf viewing, and nourishing foods like sesame seeds and chrysanthemum wine.
The Cold Dew Solar Term
On October 8th, we celebrate Cold Dew, marking one of the twenty-four solar terms in the lunar calendar. Occurring annually between October 7th and 9th, this period symbolizes the official transition from autumn to winter. With the arrival of Cold Dew, the overall climate shifts from cool to cold, particularly impacting regions north of Nanling, where winter has already taken root in places like the northeast and northwest.
As nature shifts, we observe clear signs: the lotuses wilt, cicadas silence, and the leaves of tung trees begin to yellow. The visual transformation of landscapes, accompanied by the southward migration of wild geese, vividly illustrates the late autumn scenery. Known for its cooler temperatures compared to the previous term, White Dew, Cold Dew serves as a reminder to dress warmly as the first frost approaches.
Climate Changes During Cold Dew
In our country, Cold Dew is categorized into three distinct periods:
- Arrival of Migratory Birds: Swan geese appear, migrating south in large flocks, often forming v-shaped formations.
- Birds Transforming into Clams: The appearance of clams on the beach leads to ancient beliefs attributing their emergence to transformed birds.
- Chrysanthemum Blossoms: This period is characterized by the bloom of yellow chrysanthemums.
As temperatures dip, the average daily temperature in southern regions falls below 20°C, with some areas along the Yangtze River struggling to maintain temperatures above 30°C. In contrast, many places across northern China are already experiencing winter-like conditions with average temperatures below 10°C.
Health Considerations for Cold Dew
From the perspective of traditional Chinese medicine, Cold Dew highlights the risk of dryness that can adversely affect the lungs and stomach. The focus should be on:
- Nourishing Yin: Incorporate foods that moisturize and nourish, such as sesame seeds, walnuts, white fungus, radish, tomatoes, lotus roots, and lilies.
- Avoiding Dryness: Limit consumption of spicy, dry, or grilled foods that can aggravate dryness.
- Hydration: Ensure a humid living environment, stay well-hydrated, and consume fruits with high water content like pears, apples, and grapes.
Traditional Customs of Cold Dew
Several traditions mark the Cold Dew season, intertwining cultural practices with nature’s changes:
-
Mountain Climbing: The proximity of the Double Ninth Festival makes this an ideal time for ascent. Climbing symbolizes moving beyond worries while connecting with nature.
-
Red Leaf Viewing: As autumn advances, appreciating red leaves becomes a cherished activity. Regions north of the Yellow River are particularly known for their stunning autumn foliage.
-
Nourishing Foods: In alignment with the principle of nourishing yin in autumn, consuming sesame seeds during Cold Dew has become customary. These seeds are believed to help combat the season’s dryness.
-
Chrysanthemum Wine: With chrysanthemums in full bloom, many regions celebrate by brewing and enjoying chrysanthemum wine. This traditional drink, historically known as "longevity wine," is valued for its health benefits.
- Flower Cakes: As the weather cools and flora fades, flower cakes become symbolic refreshments during mountain climbing, emphasizing the significance of this season.
The Poetic Essence of Cold Dew
The transition into Cold Dew has inspired numerous poetic expressions throughout history. Poets often capture the melancholic beauty of the declining autumn days, reflecting on themes of nature, change, and nostalgia through their verses.
Through poems that highlight the cold winds, shimmering dew, and the poignant beauty of the season, we connect deeply with the essence of Cold Dew, experiencing both the blessings and bittersweet reminders of the passing time.
In conclusion, Cold Dew represents a significant turning point in the seasonal cycle, bridging autumn and winter. Its cultural and health implications guide us to prepare for the colder months, reminding us to appreciate the beauty of nature while taking care of our well-being. As we embrace this time of transition, let us also honor the customs that enrich our understanding of this beautiful season.
