Today I would like to talk about Kidney energy.
The Kidney energy is Water and is the strongest Yin within the 5 energies.
So the Kidney is easily influenced by the cold.
The other organ which also has Water energy is the Bladder.

As you know, these two organs are related to the function of urination.
If I broaden the range, these organs control all the water in the body.
So if our body is becoming cold, the kidney and bladder try to excrete extra water in order to keep our body warm.
When Kidney energy becomes weak, we retain water under the skin, called edema. This is because we are unable to excrete water through urination very well.

Kidney energy is not only excreting water but also cleansing water.
Only about 5% of the water is excreted as urination. The other 95% is cleansed and filtrated through the kidneys and is circulated again throughout our body.
When Kidney energy becomes weak, the water is not cleansed properly. This leads to cloudy water.
Cloudy water doesn't flow smoothly and tends to accumulate, causing cataracts, Meniere's disease and gout.

Kidney energy controls the bones.
The weakness of Kidney energy causes the weakness and degeneration of bones such as osteoporosis and degeneration of the knee joints.
On the contrary, it may also produce stones in our body such as Kidney stones or urinary stones.

Kidney is weakened by the cold, so the cold causes various disorders.
The main cause of miscarriages and infertility is the weakness of Kidney energy due to an internal cold condition within the body.
Cold feet and hot flashes appear when the lower body gets cold and heat in the upper body cannot come down. This is due to weakness of Kidney energy.
