HealthDay News — According to a study published in Sleep Health, improving sleep may help reduce an individual’s sugar-sweetened, caffeinated beverage intake, and vice-versa.

Aric Prather, PhD, of the University of California, San Francisco, and colleagues analyzed self-reported sleep duration and beverage intake data from 18,779 American adults.

The researchers found that individuals who regularly slept 5 or fewer hours a night drank 21% more sugar-sweetened, caffeinated beverages like soda and energy drinks than those who slept 7 to 8 hours a night.

People who regularly slept 6 hours a night consumed 11% more of the drinks than those who got more sleep. The investigators found no link between the amount of sleep and consumption of juice, tea or diet drinks.

“Short sleep is associated with greater intake of sugared caffeinated sodas, a relationship that may have important, though unrecognized, implications for physical health. Directionality of this relationship cannot be determined from this study. Although caffeinated drinks could account for impaired sleep, it is possible that short sleep could influence one’s appetitive drive for sugared caffeine drinks,” the authors write. “Further examination of this relationship using prospective designs is warranted.”
