Yin is the cooling, moistening energy of the body (as opposed to Yang, the warming, active energy of the body).
Yin is depleted by overworking or running on empty, and not getting sufficient rest. It can also be depleted by chronic illness. When we lack this cooling lubricant, we tend to overheat and dry up.
The best way to restore Yin is to rest, and support this through diet. Avoiding stimulating and heating foods is important, such as coffee, alcohol, sugar and hot spices. You can also increase the amount of cooling and moistening foods, such as:
- Kidney beans
- Sweet potato
It is also important not to over-cool things, so avoid cold foods, such as ice cream, and only increase the proportion of these cooling, moistening foods, don’t eat them exclusively.
