Greater Heat (Dàshǔ) is the 12th solar term among the 24 Solar Terms and usually occurs between July 22nd and 24th each year. During this period, most regions in China experience the hottest days of the year, with blazing sunshine and sweltering heat lingering in the air. As an old saying goes, “Lesser Heat and Greater Heat, steaming from above and boiling below,” an apt description of the intense heat and humidity that define this time.
In ancient China’s agrarian society, Greater Heat was more than just a sign of the weather; it was closely connected to important agricultural activities. It marked a key period for harvesting early rice and transplanting late-season rice. Farmers had to work efficiently to harvest and sow in time, reflected in the saying, “If you don’t cut the rice during Greater Heat, you’ll lose a basket each day.” Greater Heat is also regarded as the hottest stage of the "dog days" of summer. People believed that during this time, yang energy reached its peak, and thus, one should follow the rhythm of nature, adjust daily routines, and avoid overexertion.
After Greater Heat comes "Beginning of Autumn," marking the gradual cooling of the weather. During this transition, people often adjust their diet in preparation for the changing season. Major Heat is a solar term where nature and culture meet; it not only carries ancient wisdom but also continues to shape daily life today. Whether through food therapy, traditional customs, or modern cooling methods, Greater Heat serves as a reminder: only by following the rhythms of nature can one pass through the hottest days of summer in comfort and good health.
