Do you know the TRUE value of sleep?


imageDo you get enough sleep? It’s all too easy to skimp on sleep when we have so much to squeeze into our finite daily allotment of 24 hours, but do you value sleep as much as you should? 

An article in today’s Daily Mail says that lack of sleep has been connected to cancer, obesity, diabetes and immune deficiency. NOW do I have your attention?

The national institute of neurological disorders says

Nerve-signaling chemicals called neurotransmitters control whether we are asleep or awake by acting on different groups of nerve cells, or neurons, in the brain. Neurons in the brainstem, which connects the brain with the spinal cord, produce neurotransmitters such as serotonin and norepinephrine that keep some parts of the brain active while we are awake. Other neurons at the base of the brain begin signaling when we fall asleep. These neurons appear to “switch off” the signals that keep us awake. Research also suggests that a chemical called adenosine builds up in our blood while we are awake and causes drowsiness. This chemical gradually breaks down while we sleep.
Since sleep and wakefulness are influenced by different neurotransmitter signals in the brain, foods and medicines that change the balance of these signals affect whether we feel alert or drowsy and how well we sleep.

Deep sleep coincides with the release of growth hormone in children and young adults. Many of the body’s cells also show increased production and reduced breakdown of proteins during deep sleep. Since proteins are the building blocks needed for cell growth and for repair of damage from factors like stress and ultraviolet rays, deep sleep may truly be “beauty sleep.”

Activity in parts of the brain that control emotions, decision-making processes, and social interactions is drastically reduced during deep sleep, suggesting that this type of sleep may help people maintain optimal emotional and social functioning while they are awake.

Sleep seems essential for our nervous system to work properly. Some believe that sleep enable neurons used during our waking hours to repair themselves.

So, back to my original question, do you get enough sleep? Do you value sleep as much as you should?
