Happy New Year! It's been cold over the New Year period.
Here is the first weather quiz of 2022♪ December 12nd was the winter solstice, but what kind of day is the winter solstice?
The winter solstice is one of the 24 solar terms, and is the day with the shortest day and longest night in the year. The photos show the longest day of the year (summer solstice) and the shortest day of the year (winter solstice).

The winter solstice signifies that the real cold and harshness of winter begins around the winter solstice, so taking a yuzu bath on the day of the winter solstice is to prepare for the real cold that is to come.

Yuzu baths can heal cracked and chapped hands caused by the cold, warm the body, and keep you 100% healthy so you don't catch a cold. It's going to get even colder from now on, so take care of your body by taking yuzu baths not just on the winter solstice!
