Study Links Soda to Poor Sleep
Adults who get the least amount of sleep—no more than five hours a night—are more likely to be heavy soda drinkers than adults who get more rest, according to a new study. For the study, researchers analyzed data on 19,000 American adults.
They found that 13 percent of people in the survey reported getting five hours of sleep or less on most nights. This group was found to drink 21 percent more sugar-sweetened beverages, 26 percent more regular soda, and 33 percent more caffeinated drinks than those who reported getting healthier amounts of sleep—seven to eight hours a night. According to researchers, the main connection was with non-diet, caffeinated sodas.
Caffeine can block the effects of a chemical in the brain that makes us feel tired. When it comes to sugar, it probably doesn’t have a direct impact on our ability to sleep—but a lack of sleep can fuel the drive to consume more sugar. In the U.S., soda is the main dietary source of added sugar, contributing to obesity, heart disease, and diabetes.
