Consuming energy drinks may result in poorer sleep and higher stress levels

In January 2020 researchers from the USA published the results of their study to assess the effect of caffeine and energy drink habits on sleep quantity, sleep quality, and perceived stress levels in nurses. Results showed that there was a significant relationship between energy drink consumption and sleep quality, sleep quantity, and perceived stress levels. Nurses who consumed energy drinks had poorer sleep quality and fewer hours of sleep compared with caffeine-only and non-caffeine consumers. In addition, nurses who consumed energy drinks had increased levels of perceived stress than non-caffeine consumers. Further research is required to assess motivational factors related to energy drink consumption as well as any health or safety implications that may be associated.
