What we know is that there are specific cleaning cells inside the brain called astroglia that are between the neurons. When they are activated, astroglia scoop up waste products and drive them towards blood vessels so they drain away from the brain.

When you are awake and hustling, this system is shut down. Only when you enter a deep sleep and delta waves prevail, do the astroglia activate and do their work.

In the #hustle culture of manic busyness, it can be hard to remember the basic facts about personal growth. Mentally and physically, human beings are built to adapt to stress, but it will not happen if we don’t take time to rest and recover. That’s when the growth occurs. We cannot grow, let alone heal, if we are constantly on the go.

As the foundation of all health and performance, sleep is something you need to take seriously. And while you may not have access to a sleep coach like the pro sports teams do, you can still put a protocol in place to help you achieve optimal sleep.

The other day, a friend of mine who used to work crazy hours told me about his desire to become a true Sleep Master. He had at long last accepted the science of sleep, which I talked about a few months ago in this blog. Exhausted all the time, his health and relationships were suffering and he was making a change.

A good night’s sleep is the foundation of physical health and mental energy.

I’m a science geek. I like to know why a particular approach to life or technique for success works. Otherwise, I tend to glaze over when faced with another “X Ways to Achieve Y Results” article. In the absence of research or evidence, I’m less likely to pay attention and less motivated to make a change in my life.

Maybe that’s just me. But I’ll assume you’re also a “but how do we know that really matters?” person and lay it out for you — on the subject of sleep.
