What is this one single thing that profoundly impacts your brain and body, both in the short- and long-term?

It's simple: sleep.

Would you be shocked to know some researchers say that "good sleep guarantees well-being and mental health"?(1) 

Why is sleep so crucial? What is sleep, and how do we do it? How much is "enough quality sleep"? How does it do these incredible things for health and wellness? And, most importantly, how can you get better sleep?

Sleep is an active process. Your body might be still, but your biology is bustling with activity. All of that internal nocturnal activity is crucial for living well.

Sleep also plays a massive role in detoxification. Your body has been using sleep to recharge and repair itself since before you were born. It’s no surprise that many sleep disorders are now linked to chronic pain, decreased cognitive function, depression, chronic pain, and neurological diseases, like Alzheimer’s.
