If you're pushing your waking life and brushing off the dream world, you could be inadvertently lowering your sex drive.
A new study published in The Journal of American Medical Association has found a lack of sleep may have a direct impact on the amount of testosterone pumping through a man's body.
Men's testosterone levels naturally decline by roughly 1% to 2% a year with age, but researchers found a lack of sleep could cause a 10% to 15% DECREASE!
In the small study, 10 men with an average age of 24 were monitored while sleeping 10 hours for 3 nights, then only 5 hours for another eight.
The significantly decreased testosterone levels were discovered on the last day of the 5-hour sleeping phase, during which their blood was sampled every 15-30 minutes.
Though small in scope, similar studies have found similar results. In 2007, a study on 12 older men between the ages of 64 and 74 discovered “measured amount of nighttime sleep in healthy older men was found to be a significant and independent predictor of their morning total and free testosterone levels.”
Testosterone won't just affect your sex life either! Research shows those levels play an important role in a man's overall health, including building strength, muscle mass and bone density.
Sleep tight, fellas!
