The Study
There are studies showing that sleep deprivation reduces testosterone by the equivalent of 10-15 years of aging. One week of 5 hours a night creates a pre-diabetic state.
Growth Hormone
70% of your Human Growth Hormone is released in slow-wave sleep. You literally grow in your sleep. If you cut it short, you are short-changing your gains.
Cognitive Drive
You can't train hard if your nervous system is fried. Sleep restores willpower and focus.
The Priority
Before you look for a magic pill, look at your pillow. If you aren't getting 7-9 hours, nothing else matters.
