Individuals aged 45 to 64 with gastroesophageal reflux disease (GERD) reported disturbed sleep, according to a Sleep in America survey conducted by the National Sleep Foundation. The poll of 2000 individuals found that approximately 50% of the respondents reported having trouble falling asleep, which affected their work productivity and leisure activities.
A separate study of sleep habits on 15,314 adults showed that 25% experienced heartburn that interrupted their sleep ≥2 times a month. Furthermore, the study found that participants who consumed carbonated soft drinks were 24% more likely to be awakened by heartburn, compared with individuals who did not drink carbonated beverages. Taking a benzodiazepine sleeping pill also increased the incidence of nighttime heartburn. (The results were reported in Chest, May 2005.)
