It is the first solar term of summer and occurs when the sun reaches 45 degrees north latitude. This marks the official start of summer, and is often referred to as the 'first day of summer'. The name 'Summer Solstice' refers to this time of year, which was believed to be the longest day of the year by the ancient Chinese. It is also known as 'Lidu', or 'Sixth Month', named after a sixth month in the Chinese lunar calendar, during which many crops are harvested and people are busy with harvest work. The start of summer marks the beginning of the hottest time of year, with temperatures often reaching their peak before gradually decreasing towards autumn. Many festivals and celebrations take place around this time, such as the Mid-Autumn Festival, which honors the full moon. Traditional Chinese medicine suggests that this is a good time to focus on nourishing one's heart and spirit, with foods rich in vitamin C and other nutrients being particularly beneficial. The concept of 'nourishing the heart' refers to the idea that our hearts are connected to our spirits, and by eating nutrient-rich foods, we can cultivate our inner energy and vitality. Some common foods recommended during this time include: citrus fruits, apples, pears, chestnuts, mushrooms, and sweet potatoes. The focus is on consuming foods that are easy to digest, rich in vitamins and minerals, and have a balancing effect on the body's energy. Additionally, warm and nourishing drinks such as ginseng tea, licorice root tea, and honey wine are often consumed during this time to promote vitality and longevity.
