Do you wake up at the same time every night? You might not even notice. In traditional Chinese medicine, in acupuncture and acupressure, meridians or 'energy' channels have been used for thousands of years. These are connected to our natural rhythm and provide energy to certain parts of the body. And depending on what time you wake up at night, your body tells you certain physical and emotional problems you may be experiencing. And therefore, waking up at these hours should not be ignored in any way.
