Lack of Sleep: Your Brain Eats Itself

I’ve written a couple of times about the importance of sleep for diabetics and non-diabetics alike. Matthew Walker’s discussion with Joe Rogan was a bit of a wake up call for me. His book Why We Sleep goes a long way in explaining the science behind his arguments.

N.B., personally I found the science a bit of a chore. For those who don’t need convincing the conclusion is this: get at least seven hours of sleep every night (preferably eight) or you will massively increase your chances developing cancer, heart attacks, Alzheimer’s, you name it.

Dr Mercola has an interesting article out that argues sleep deprivation causes astrocytes, cells involved in brain cleansing and regeneration, to function abnormally. The result:

“When astrocytes are functioning abnormally, they can eat and destroy healthy brain synapses, increasing your risk of Alzheimer’s and other neurodegenerative diseases.”

The article is definitely worth reading. He also offers a lot of good advice on how to achieve consistently good sleep.
