How to increase the human growth hormone naturally?

Sleep well to grow: Growth hormone is released during sleep-so if you can get good quality sleep, that will help your body regulate it's own hormones. We call sleeping well-'sleep hygiene'. Also, before the invention of the electric light, diaries indicated we slept TEN hours a night on average, not just 8. Try keeping a sleep log to see if you're getting good enough sleep (running a sleep deficits means you are not)
