This rewritten guide for Dahan (Great Cold)—the final and coldest solar term of the year (occurring on January 20, 2026) — focuses on the philosophy of dynamic balance. In Traditional Chinese Medicine (TCM), there is no "one-size-fits-all" formula (法無定法); instead, one must learn to harmonize the body with the environment through constant adjustment.
1. Late-Night Snacks & Sleep: Energy Management
To Eat or Not? The principle is: "Do not stay hungry, do not stay cold." In winter, the body consumes more energy to produce heat. If hunger prevents sleep or causes your body temperature to drop, a light, warm snack (like porridge) is acceptable.
The Cost of Late Nights: Winter wisdom suggests "sleeping early and rising late, waiting for the sun." Staying up late drains the Kidney Essence (Jing). While summer late nights strain the "Heart Fire," winter late nights damage your very foundation.
Age Matters: Young people have faster metabolisms and higher heat production. Seniors, however, must be stricter with warmth to prevent cardiovascular issues triggered by sudden cold.
2. Hydration & Organ Care: Less Salt, Less Water, More Bitterness
Water Intake: Not everyone needs 2000cc daily. Since we sweat less in winter, reducing water intake slightly helps lighten the burden on the Kidneys and prevents fluid retention (dampness).
Nourishing Kidney & Heart:
Less Salt: Salt enters the Kidneys, but excess salt damages the blood.
More Bitterness: Bitter flavors enter the Heart. Dishes like Mustard Green Chicken Soup or Bitter Melon with Pineapple Chicken Soup help circulate Qi and protect the Heart.
3. Humid Cold (Taipei) vs. Dry Cold (Kyoto)
Perceived Temperature: Due to high humidity, the cold in Taipei is "penetrating" and conducts heat away from the body faster than the dry snow of Kyoto.
Dietary Strategy: In humid cold, focus on "Warming the Stomach and Dispelling Dampness." Use soups like Mutton Soup with Angelica or Pig Tripe Soup with Peppercorns, utilizing ginger, pepper, and chili to combat cold-dampness.
4. Skin Care: Avoid Over-Stripping Oils
The Vicious Cycle: Hot showers and hot springs in winter strip away natural oils, leading to cracked skin.
Oil Sealing: After bathing, while skin is still damp, use lotions or natural oils to "seal" and lock in moisture.
5. The Stomach: Thermal & Emotional Center
Heat Source: The stomach is a vital heat-producing organ; hunger is a survival instinct.
Tension vs. Hunger: Modern hunger often stems from anxiety or aesthetic pressure rather than physiological need. Practice Self-Awareness and listen to your body rather than social frameworks.
Winter Cooking:
White Radish: "Winter radish" helps descend Qi and aids digestion, preventing constipation caused by over-nourishing or inactivity.
Cooking Methods: Roasting, frying, and searing are suitable for winter to add calories and "bitter-charred" notes (like the skin of a roasted sweet potato).
6. Alcohol & Medicine: Moderation is Key
Alcohol can circulate blood and open the meridians. During Dahan, moderate amounts of distilled spirits (Kaoliang, Whiskey, or Rice Wine) can help expel cold and invigorate circulation.
7. Key to Winter Warmth: Avoid Wind and Damp
Critical Areas: Protect the head, feet, and limbs. Wearing wool socks and slippers indoors prevents "cold from rising through the feet."
Rest & Movement: Sleeping until you wake up naturally is the best repair. Exercise should focus on "maintaining peripheral circulation" rather than intense workouts that cause heavy sweating.
Conclusion: The Four Pillars of Self-Healing
If a person can sleep well, eat well, eliminate well, and move well, 80% of minor ailments can be self-healed. Medicine is only needed when the body's Qi becomes severely unbalanced. Observe your physical sensations in the moment and give your body the care it truly needs.
