Carbonated drinks can be the cause of sleep problems such as insomnia or fragmented sleep. These drinks are rich in acid which can lead to nighttime heartburn, possibly indicative of a severe degree of gastroesophageal reflux disease (GERD), according to researchers. When heartburn occurs at night, it is considered to be suggestive of a more serious or advanced form of reflux disease. Heartburn during sleep can also cause nighttime awakening, sleep loss, and daytime sleepiness.
