DARK ,SLEEP & FAST
Insomnia has always been caused by a sense of insecurity, why does this person feel unsafe ? Why is she afraid to sleep ? What has kept a person vigilant all these years ,thats what we need to understand. Could illness or anguish be causing it.The most common cause of sleep disorders is depression and treating depression with sleeping pills just worsens the situation.
Mindful meditation Mindful meditation involves focusing on the present without letting other thoughts distract you ,this training helps us work on ourselves ,it helps us to accept our thoughts and feelings which will lead to a better night sleep.
During the day, exposure to natural light combined with physical exercise improves the quality of our night sleep so , our day time activity clearly influences how we sleep .Poor sleep can be even be a risk factor for alzheimers disease. The brain is so stressed out during normal wake time that it cannot do its normal housekeeping and we speculate that this might be the biological foundation for sleep. The purpose of sleep is to clean the brain of all the waste products that builds up during wakefulness .
Nobody had really looked in the brain on how does the brain get rid of waste products and the question turns out to be would glial cells be involved in that?
Glial cells nourish our neurons ,supplying them with oxygen and nutrients ,another major purpose these glial cells serve ,in the brain the arteries are surrounded by space in which some fluids circulates freely when ,we fall into a deep sleep glial cells open canals which releases this fluid,it washes over the neurons cleaning away the waste which was collected during waking hours so glial cells are key to brain cleansing ,once the waste is transported out of the brain its dumped back into the blood circulation and you can regard the liver as our professional recycling plant for such waste.
The flow of the fluid that cleanses the brain is much more effiecient when we are in deep sleep ,if you are in lighter stages of sleep or if you are awake it does not work .The conclusion is this the deeper your sleep ,the longer your sleep,the better you clean the brain .
