Yin Deficiency
Yin and yang are two complementary, yet opposing forces that make up the whole of every organism, and all aspects of life. When both are in harmony, there is balance. Within our bodies, when our more cooling & nourishing “yin” functions are deficient, we may experience symptoms that are warm or dry in nature, like night sweats or a dry throat.
Yin and yang are foundational concepts in traditional Chinese medicine that help to explain the balance of all things. “Yin” denotes Earth energy, and is considered more feminine in nature. It is associated with rest, nourishment, stillness, receptivity, coolness, etc., as opposed to the more warm and action-oriented nature of “yang.”
All things contain both yin and yang, including our bodies. When we experience a yin deficiency - that is, when we lack sufficient “yin” to balance out the nature of “yang” within our bodies - this means that we lack sufficient hydration and nutrients to nourish our blood and kidneys, resulting in symptoms of heat and/or dryness.
An example would be a person who is chronically ill and undergoing treatment that might be exhaustive to their internal organs and systems. Over time, if they are not nourishing their more yin (cooling and hydrating systems) through diet, supplementation, and adequate rest, they will become out of balance, experiencing manifestations of internal heat and dehydration, like dry mouth, dry skin, brittle hair, feeling hot, skin rashes, or even cognitive and memory issues.
From a Western understanding, yin and yang are very much related to our hormone balance, as well as our kidney health and overall fluid balance.
