Our point of view...
An average healthy brain that lives to be 90 years of age will have on the average spent 32 years in what we consciously call sleep. This statistic points to sleep as being a highly significant factor in human existence.
Sleep is a natural faculty of the human brain. If the sleep is of good quality, the individual associated with such a brain will predictably experience much enjoyment and satisfaction throughout the course of their life. However, if the sleep quality is disrupted and becomes poor then the individual will predictably wake with low mental energy reserves that lead to mental fatigue, boredom, anxiety, loss of enjoyment and diminished satisfaction in their endeavors.
Statistically speaking, the brain uses no less and no more mental energy when we are engaged in sleep than when we are awake, consciously and deliberately living our lives. In other words the brain is just as active during sleep as it is when we are awake. It appears that the brain NEVER sleeps. It then follows that the brain needs access to good mental energy reserves while we are sleeping in order to do its work well. Less than adequate mental energy reserves, diminishes the brain ability to perform good sleep and results in an individual waking mentally fatigued and unable to find enjoyment and satisfaction.
But what is the brain doing while we as individuals are experiencing sleep? We think that the brain is engaged in a least two significant activities, memory consolidation and secondly mental energy restoration. If a brain attempts to initiate the sleep process with low mental energy or mental fatigue, the sleep process quality is less than necessary to make the sleep process work.
Mental fatigue is common in our society and world at large. The mental fatigue is associated with sensory overload brought on by too much information, more than the brain can adequately manage. Unmanaged sensory loading is known as psychological stress. It is this stress that fatigues the prefrontal cortex of the brain and disrupts the sleep process.
What can you do to help with sleep and mental fatigue. Use Neurofeedback to train your brain to be efficient in energy usage and you will build better stress management ability.
