Andrew Knoll for The New York Times:
Every night, the Sharks are encouraged to swallow chamomile, lavender and tart cherry juice, a melatonin producer that also combats inflammation. Augmenting players’ consumption of zinc, magnesium and other nutrients has also helped the Sharks get better, more reliable sleep while diminishing their use of prescription drugs such as Ambien. In addition, the Sharks’ staff suggests that players control their sleep environment, minimizing ultraviolet light and keeping their rooms quiet, dark and cool.
For an athlete, the benefits of proper rest are manifold and the effects of sleep deprivation severe.
Any research proving the benefits of sleep only makes my alarm that much more annoying each morning.
