How a lack of sleep affects your body

A couple of days ago, I told you how to sleep more deeply. But why is sleep so important? Here's list of what a lack of sleep can do to you:
- You body has difficulty processing glucose -- meaning you can't metabolize sugar properly, which makes your cells unhealthy ... and the rest of your body too.
- You're in a constant state of alertness, because your levels of cortisol, a stress hormone, are spiked. This means you'll be under constant stress and will have trouble resting -- meaning you'll have trouble sleeping
- Your immune system weakens. I know about this all too well. When I was a starving student, pulling all-nighters and working evenings and weekend to make ends meet, I was constantly sick. Now that I get a proper amount of shut-eye, I haven't been sick in ages.
- You're moody.
- You're not mentally sharp
- You crave junk food. And because you're not at you peak performance, you're more likely to give in to those cravings.
