Sleep. Not just a brain thing


This is a fascinating article that illustrates that sleeping is a more complex activity than we know: Sleep Evolved Before Brains. Hydras Are Living Proof. | Quanta Magazine

I’ve always associated sleep with something our brains need to have in order to survive. (Sleep deprivation is one proof of that.) But I have been won over to the idea that sleep is a more fundamental property of living things, brain or no brain.

Read the article: I think you’ll find it fascinating too.

Two good articles on sleep

Man and dog sleeping

If you are having sleep problems, read #1. If you need to understand why you need to sleep more, read #2.

  1. Shuteye and Sleep Hygiene: The Truth About Why You Keep Waking up at 3 a.m.
  2. Scientists Now Know How Sleep Cleans Toxins From the Brain | WIRED

I especially liked #2. I had a long held belief that is why we sleep. It’s satisfying to see it established by science.

We all need clean and shiny brains. To do that, get some sleep.

Why running may help your brain

Based on this older study (For Your Brain’s Sake, Keep Moving – The New York Times), it seems like running helps the brain grow better. It’s a good read. It may also explain, at least in part, why people’s brains are not doing so great lately with the lockdown due to the pandemic.

We rightly attribute running to helping our muscles and our cardiovascular system. It seems to help our nervous system as well. Try to get out and move if you can.
