The winter climate in Seoul is cold and dry, with temperatures often dropping below zero, especially in the early morning and at night, when the perceived temperature is even lower. Recent weather forecasts indicate that cold air continues to affect most parts of South Korea. The average daily temperature in Seoul may fluctuate between -5 ℃ and 3℃, accompanied by northerly winds. The wind-chill effect is obvious, which can easily lead to rapid loss of body heat. Therefore, when traveling to Seoul or within the local area, it is essential to take good measures to keep warm and protect against the cold. It is recommended to wear multiple layers of clothing such as down jackets, thick cotton-padded clothes and thermal underwear, and to wear scarves, gloves and thermal hats, especially to protect the head, neck and limbs from getting cold. Indoor heating systems are usually well-developed, but when going in and out of the room, one should pay attention to adding or removing clothes in time to prevent colds or other health problems caused by excessive temperature differences. In addition, dry climate can also easily cause the skin to crack. It is advisable to use moisturizing skin care products appropriately to keep the body hydrated. In conclusion, during the cold season in Seoul, dressing scientifically and taking reasonable protective measures are the keys to ensuring comfort and health.
