"Yeet hay" (熱氣, pronounced jit6 hei3 in Cantonese) is a term deeply rooted in the everyday lives and health beliefs of many Cantonese-speaking communities. While it has no direct equivalent in Western medicine, "yeet hay" is a foundational concept in Traditional Chinese Medicine (TCM) and Chinese culture, shaping how people think about food, health, and balance.

What Does "Yeet Hay" Mean?
"Yeet hay" literally translates to "hot air" but is best understood as a state of internal "heatiness" or excess yang energy in the body. According to TCM, health is achieved by maintaining a balance between yin (cool, passive) and yang (hot, active) energies. When this balance tips and yang dominates, the body is said to be "yeet hay," leading to various symptoms:
Sore throat
Canker sores
Acne or skin rashes
Fatigue
General discomfort
Some also use "yeet hay" metaphorically to describe someone who is irritable or angry, although its primary use relates to physical health.
What Causes "Yeet Hay"?
"Yeet hay" is most commonly triggered by dietary choices and lifestyle factors. Foods considered "heaty" (yang) include:
Fried, oily, and spicy foods
Red meats like beef and lamb
Certain tropical fruits (lychee, mango, durian)
Seafood such as lobster and prawn
Other factors—such as stress, lack of sleep, and environmental heat—can also contribute to this imbalance.
How Is "Yeet Hay" Managed?
To counteract "yeet hay," the traditional remedy is to consume "cooling" (yin) foods and drinks, aiming to restore balance:
Cooling soups (e.g., winter melon soup, watercress soup)
Herbal teas known as "leung cha" (涼茶), such as chrysanthemum tea
Fruits like watermelon, pear, and starfruit
Vegetables grown in water, such as lotus root and watercress
Pairing foods is also common: for example, eating mangosteen (a cooling fruit) with durian (a heaty fruit) to balance their effects.
Is "Yeet Hay" Scientifically Proven?
The concept of "yeet hay" is not recognized in Western medicine, though some compare it loosely to inflammation, as both involve the body's response to certain triggers and can produce similar symptoms. However, TCM's framework is based on centuries-old holistic principles rather than modern scientific research, leading some to view it as unscientific or anecdotal.
Why Does "Yeet Hay" Matter?
For many in Cantonese and broader Chinese communities, "yeet hay" is more than a health term—it's a cultural touchstone. It influences daily choices, from what to eat to how to care for oneself and loved ones. Even if the science is debated, the concept endures, shaping habits and conversations across generations.
In Summary
"Yeet hay" reflects the rich tapestry of Chinese health beliefs, emphasizing balance, prevention, and the interconnectedness of diet, environment, and well-being. Whether you believe in its literal effects or see it as a cultural metaphor, understanding "yeet hay" offers a window into the values and practices of Cantonese life.
