What is “Summer Heat”? 了解“暑邪”


In Traditional Chinese Medicine, there are six factors from the environment that contribute to illness and cause imbalances in our body. They are:

pathogenic wind 风
pathogenic cold 寒
pathogenic summer-heat 暑
pathogenic dampness 湿
pathogenic dryness 燥
pathogenic heat (fire) 火

We, as part of nature, constantly contact with these natural factors. Under normal condition, our body can adapt to the environmental changes, however, if the harmonious relationship between human beings and nature is broken, an imbalanced body will become unable to adapt itself to the changes, leading to the occurrence of disease. Under such condition, the six natural climatic factors become pathogenic factors. These factors can be either external (exogenous) or internal (endogenous) and both are interrelated. External factors are often the cause or triggers of internal factors.




Summer Heat 暑

Pertaining to Yang, Summer, Fire element, Heart, summer-heat usually appears after summer solstice and before autumn solstice. The attack by summer-heat is either due to hot weather or due to low adaptability of the body to the climate changes.

Summer-heat is characterized by the following features:

1. Summer-heat is hot: The disease caused by summer-heat is usually marked by a series of yang symptoms such as high fever, dysphoria, reddish complexion, thirst with preference for cold drinks.
2. Summer-heat disperses and elevates: Summer-heat disturbs the mind when it rises in the body, leading to dysphoria and dizziness or even sudden coma and unconsciousness in severe cases. Summer-heat induces sweating, consuming and dispersing body fluid which leads to thirst and reddish/scanty urine. If there is profuse sweating, Qi will be lost or if you will, "evaporate," eventually bringing on shortness of breath and lassitude due to Qi deficiency.
3. Summer-heat fumigates dampness: Dampness is exuberant in summer and often mixes up with heat to attack people. Disease caused by summer-heat-dampness is often, apart from fever and extreme thirst, characterized by lassitude of the four limbs, acne, oily and red skin, inflamed gut, chest oppression, vomiting and unsmooth loose stool, etc.

Endogenous Summer Heat

Please refer to Endogenous Fire.

To recover from summer-heat invasion, we need cooling and calming foods and herbs.
