Tart cherry juice drinkers gain sleep advantage
Americans seeking a better nights sleep may need to look no further than tart cherry juice, according to a new study in the European Journal of Nutrition. 1 An international team of researchers found that when adults had two daily glasses of tart cherry juice, they slept 39 minutes longer, on average, and had up to 6 percent increase in overall sleep efficiency (significantly less non-sleep time in bed), compared to when they drank a non-cherry, fruit cocktail.
In a study conducted at Northumbria University, twenty healthy adults drank two servings of tart cherry juice concentrate (30mL of 100% pure Montmorency juice concentrate per serving, diluted in a half pint of water; provided by CherryActive, Sunbury, UK) or a non-cherry fruit drink for seven consecutive days at a time one serving when they woke up, and another before bed.
