What is Human Growth Hormone?

HGH – Human Growth Hormone is a hormone, which is produced naturally by our bodies. It is a peptide hormone that stimulates muscle growth, cell reproduction, and cell regeneration. It is key in human development.

HGH plays an important role in our energy, vigor, stamina, skin, immunity, and body’s ability to build and grow muscle.


What’s the hype?  

Human growth hormone is a huge topic as it relates to athletic performance and muscle growth. The pituitary gland releases bursts of HGH producing the highest levels following SLEEP, exercise, and trauma. Under normal conditions, more HGH is produced at night than during the day


  • Men- experience 60 to 70% of daily human growth hormone secretion occurs during early sleep, which is typically the deepest sleep of our cycles. 
  • Women- spend about two times as much time during the day actively secreting human growth hormone. 

In both men and women, without adequate sleep, the production and ability of HGH to work its magic is inhibited. 

Key Takeaway-Poor quality sleep can negatively impact human growth hormone levels.


The magic happens during sleep…

Sleep has a profound effect on muscle growth and physical well-being. We need to catch the right amount of Zzz’s, especially when trying to build and grow muscle.

During REM sleep the body-

  • Restores tissue, organs, and muscle
  • Replenishes immune cells
  • Circulates human growth hormone.

Each phase of our sleep cycle contributes to muscular repair and muscle growth in different ways. This is why it is important to not just sleep enough but to sleep well!

In March of 2018,  a systematic review was conducted and later published in The National Library of Sports Medicine, concluding that after several different sleep interventions, evidence suggests that sleep extension had the most beneficial effects on subsequent performance. This means, the more one slept, the better and more consistently they would perform at their best. 


Recharge the Brain & Build Muscle

The only way to recharge the brain fully is to get adequate sleep.

Resting the brain has obvious implications for athletes given that mental alertness is desired during the day, especially during training. Motivation levels are highest when mental alertness is highest. Studies suggest that it is during REM sleep that proper functioning of the brain and alertness is fully rejuvenated.
