One of the most notable benefits of a healthy sleep schedule when it comes to packing on muscle is that sleep and hormone secretion are intricately linked. And one hormone in particular is especially affected by sleep – human growth hormone.
This hormone, also known as HGH, plays an integral role in physical performance and helps improve tissue repair and allows the body’s muscles to both recover and grow. In fact, weightlifters around the world have actually been supplementing their nutritional regimen with this hormone since the 70s.
And while experts say that HGH is certainly no magic bullet when it comes to bulking up, it has been shown to give up to a 15% benefit to muscle gains when administered properly. Not too bad at all.
When it comes to natural production, almost 75% of HGH is actually released during the sleep cycle. The release schedule tends to happen in a “pulse” fashion, usually occurring during the beginning portions of stage 3. As the body enters the third stage, a quick burst of hormone release occurs before moving on to the fourth stage.
Throughout the nighttime, your body goes through an entire sleep cycle (i.e. from stage 1 to stage 5) about every 90 minutes. As such, if you aren’t getting as much sleep as your body needs to really recover, you could be missing out on several important chances for HGH release, making your exercises less effective and stifling your gains.
