About 70% of human growth hormone is released during Deep Sleep (Slow-wave sleep). This hormone is responsible for tissue repair, muscle growth, and bone density—critical factors for staying on the mats long-term.
"Sleep is the single most effective thing that we can do each and every day to reset our brain and body health, but one out of every three people that you pass on the street is struggling to get the sleep that they need." – Dr. Matt Walker, Neuroscientist and Sleep Expert
During REM sleep, your brain "replays" the techniques you practiced during the day. Whether it's a new BJJ transition or a Boxing combo, sleep moves these movements from short-term memory to long-term "muscle memory".
Here is why sleep deprivation is a death sentence for your performance:
Reaction Time: Research shows that being awake for 19 hours is equivalent to a blood alcohol concentration (BAC) of 0.05%. In a fight, a 0.1-second delay is the difference between a slip and a knockout.
Accuracy & Speed: A Stanford study on athletes found that increasing sleep to 10 hours per night improved sprint speed and increased hitting accuracy by 9%.
Injury Risk: Athletes who sleep less than 8 hours per night are 1.7 times more likely to get injured compared to those who sleep over 8 hours.
Morning: Get 10-30 minutes of natural sunlight within an hour of waking to set your circadian rhythm.
Night: Avoid blue light from screens 60 minutes before bed. Blue light suppresses Melatonin, the hormone that tells your brain it’s time to repair.
Your core body temperature needs to drop by 1-3 degrees to fall asleep.
Keep your bedroom between 65-68°F (18-20°C). A warm bath before bed can actually help trigger this cooling process.
Prioritize natural compounds that calm the nervous system rather than sedatives:
Magnesium Threonate/Bisglycinate: Supports muscle relaxation.
L-Theanine: Reduces post-training anxiety and mental chatter.
