Tweak your sleep schedule
You know the old saying: You snooze, you lose? Well, not according to a recent Stanford University study. It found when members of the school's women's tennis team extended their sleep to 10 hours a night, they enjoyed faster sprinting times and increased hitting accuracy. "Sleep is the body's time to heal, restore, rebalance and replenish itself with nutrients and cellular repair on every level," said Fred DeVito, the co-creator of Exhale Spa's Core Fusion program. But 10 hours, who has the time? The experts say just seven hours of snoozing will keep your body primed.
