Sleep: What Does Sleep Actually Do?

Sleep is the most important thing on this list. It's the foundation everything else is built on.

Sleep sits underneath everything else

While you're asleep your body is healing, repairing and balancing hormones. Your mind gets the same treatment. That's why a run of bad nights shows up as low mood and poor decisions rather than only as tiredness.

Short sleep makes every other part of your health harder work. You'll be hungrier and you'll reach for easier options. You'll get less back from your training. Most of all, you'll be more likely to make bad decisions in every aspect of your life.

What a good night gives you

  • More energy through the day.
  • A steadier appetite, so eating well takes less effort.
  • Better recovery from whatever you've done that week.
  • Clearer thinking and a better mood.
Remember

Everything else on your list gets easier once your sleep is in order. Start here.
