In a world that is constantly plugged in, constantly moving, and constantly praising being on the move, sleep gets looked down upon and neglected.
When it comes to your health and fitness, there are so many benefits that come from proper sleep. So much so that sleep should never be taken lightly.
Many hormones (like growth hormone) are secreted at it's highest levels during sleep. This means that all your hard work doing resistance training may be wasted if you're not giving your body proper sleep.
Some simple ways to prepare your body for sleep are:
Turning off all lights (including devices) prior to bedtime
Reading prior to bedtime
Turning off electronics and keeping yourself from exposure to light before bed can help your body better release the hormone melatonin.
