A solid, steady energy level is very important for the brain. The brain uses almost one-third of our calories. Any fluctuations or low levels of energy will have enormous impacts on our nervous system and emotions as well.
This has been demonstrated and is well-known in the case of hypoglycemia. In this condition, the brain does not receive a steady supply of glucose. Common symptoms can mimic many emotional and physical disorders. These include fatigue, depression, anxiety, confusion and even violence and psychosis.
Emotionally speaking, when one is tired, decision-making and all other mental and emotional factors are more difficult. Thousands of people today suffer from low energy levels. This often results in feelings of depression, anxiety, mood swings, irritability, withdrawal and more.
