Sleep is a part of the natural interplay of yin and yang in the body.
- Yang energy is dominant when we are awake and active: fuels the body’s activities and keeps us warm and alert.
- Yin energy rules sleep (cooling, quiet and nourishing character): it helps to slow down the body’s activities, so that it is relaxed and calm for a good night’s sleep.
When this natural rhythm is disrupted, there is an imbalance of yin and yang qi, which results in insomnia.
