Most guys think low testosterone is just about getting older. But the research says your sleep might be doing more damage to your hormones than your age ever will. A 2014 study out of Australia states: "More recently it has become clear that the production of testosterone is dependent on sleep generally reaching the peak during the first 3 h of uninterrupted sleep, and at least in young men at about the time of the first REM episode." The longer the REM sleep latency, the slower the rise in testosterone. So if you're not getting into deep, quality sleep... Your body simply isn't making enough testosterone. A University of Chicago study published in JAMA found that men who slept less than five hours a night for one week had significantly lower testosterone levels than when they had a full night's sleep. The researchers found that skipping sleep reduces a young man's testosterone levels by the same amount as aging 10 to 15 years! Whoa! The effect of sleep deprivation on testosterone may be even more pronounced with age... In older men, sleep deprivation produced a greater decrease in testosterone, and recovery was delayed compared to younger men. If you're training hard but sleeping poorly, you're fighting your own biology. Testosterone drives muscle growth, bone density, fat loss, energy, and mood. If you're over 30 and you're not taking sleep seriously, you're leaving performance and health on the table. Every. Single. Night. Is there anything that @Keegan Hanks mentioned in the video that you've tried that has helped you sleep better? Is there anything that was NOT mentioned...?
