Summer Solstice · Introduction to the Solar Terms
The Summer Solstice, the tenth of the 24 solar terms, is the day with the longest day and the shortest night in the Northern Hemisphere. The summer solstice of 2025 falls on June 21st, when the sun directly shines on the Tropic of Cancer, marking the official arrival of midsummer. In ancient calendars, the summer solstice was not only a node of astronomical phenomena but also an important time coordinate of agricultural civilization. The ancients, by observing the changes in the sun's shadow, designated the summer solstice as the sign of "the longest day and the shortest shadow", and used this to calculate the farming season and formulate calendars.
From an astronomical perspective, the Summer Solstice is a crucial moment for the transition between Yin and Yang. The ancients believed that "Yin begins to emerge on the Summer solstice", although the daytime reaches its peak, Yin energy has quietly begun to sprout and Yang energy is gradually waning. This philosophical thought of "extremes lead to reverses" has profoundly influenced traditional Chinese medicine for health preservation and folk culture. In agricultural activities, after the summer Solstice, the temperature rises and precipitation increases, and crops enter a period of rapid growth. Farmers need to strengthen field management, prevent drought and flood, and ensure a bountiful autumn harvest.
The phenological characteristics of the Summer Solstice are distinct: deer antlers start to fall off, cicadas' chirping gradually increases, and shade-loving plants such as Pinellia grow in the forest. These natural phenomena were compiled by the ancients into the "Book of Rites: Monthly Orders", serving as the basis for observing the weather and guiding agricultural activities. Modern meteorology also confirms that after the summer Solstice, the subtropical high pressure system moves northward, and most parts of China enter the rainy season. Extreme weather occurs frequently, and it is necessary to be vigilant against disasters such as heavy rain and high temperatures.
Summer Solstice · Solar Term Customs
The Summer Solstice is not only one of the 24 solar terms but also a festival among the "Four Seasons and Eight Festivals" in ancient times. Since ancient times, there has been a custom among the people to worship gods and ancestors on the Summer Solstice. In addition, after the Summer Solstice, people generally consume cool and nourishing soups, herbal teas, and plum soup to escape the heat.
Worship the gods and pray for blessings
The Summer Solstice sacrifice to the gods was one of the most important solar term sacrifices in ancient times. In the Zhou Dynasty, there was already a record of "offering sacrifices to the earth on the central hill of the marsh on the summer solstice". The emperor had to lead all the officials in person to hold a grand ceremony to pray for favorable weather and a bountiful harvest. Among the common people, the custom of "worshipping Heaven" is popular. They set up incense tables in their courtyards and offer new wheat and fruits to express their gratitude to heaven and earth for their nourishment.
Summer diet
The dietary customs on the Summer Solstice are centered around "clearing heat and relieving summer heat". In the north, there is a saying that "dumplings are made on the Winter Solstice and noodles on the Summer Solstice". Noodles symbolize "longevity", and when paired with refreshing ingredients such as shredded cucumbers and minced garlic, they are both appetizing and refreshing. In the Jiangnan region, "Summer Solstice cakes" are popular. They are made by kneading wheat flour and filling them with red bean paste or green vegetables, symbolizing "trying new things". In addition, there are customs of eating wontons and drinking herbal tea in various places.
Recreational activities
The entertainment activities on the Summer Solstice are full of the charm of the common people. In ancient times, women had a custom of giving fans as gifts. They would present round fans painted with flowers and poems to their relatives and friends, which not only conveyed coolness but also expressed their affection. Children play the "grass fighting" game, twisting grass stems together. The one who breaks loses. These activities not only relieve the summer heat but also serve as a bond for neighborhood socializing.
Summer Solstice · Daily Life and Health Preservation
After the Summer Solstice, the Yang energy scatters outward and the Yin energy sinks inward, making the human body prone to a state of "external heat and internal cold". Traditional Chinese medicine emphasizes "nourishing Yang in spring and summer". At this time, health preservation should focus on "nourishing the heart and calming the mind, clearing heat and eliminating dampness".
Dietary adjustment
During the Summer Solstice, it is advisable to have a diet that is "less pungent and more sour". Reduce spicy foods like chili peppers and Sichuan pepper, and increase the intake of sour ingredients such as Chinese plums and hawthorn to quench thirst and reduce sweating. Recommended dishes include mung bean soup and winter melon, coix seed and pork rib soup. They can not only clear heat and relieve summer heat, but also strengthen the spleen and remove dampness.
Regular schedule
On the summer solstice, days are longer than nights. One should adjust their daily routine in accordance with nature. It is recommended to go to bed before 10 p.m., get up at 6 a.m., and take a 30-minute nap at noon to replenish energy. When sleeping, avoid direct exposure to air conditioners or fans. You can choose a thin quilt to cover your abdomen to prevent cold air from invading. In addition, in summer, the pores of the human body open up. After exercising, it is necessary to dry the sweat in time to avoid catching a cold.
Exercise for health preservation
It is advisable to choose early morning or evening for exercise on the Summer Solstice to avoid the hottest periods. Traditional exercises such as Tai Chi and Baduanjin can harmonize qi and blood and enhance immunity. Low-intensity exercises such as swimming and yoga can not only exercise the heart and lungs but also relieve stress. After exercising, it is necessary to replenish light salt water to prevent electrolyte imbalance. The clothing and matching for summer sports not only affect the comfort of the exercise but are also closely related to physical health. Appropriate sports equipment can help us dissipate heat better and reduce resistance during exercise.
