The Claim
Energy drinks containing 240 mg of caffeine are associated with a greater negative impact on subjective sleep quality than coffee containing 240 mg of caffeine, with 46.6% of users reporting poor sleep after energy drink consumption compared to 29.7% after coffee consumption.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who drink energy drinks with 240 mg of caffeine report poor sleep more often than people who drink coffee with the same amount of caffeine.
See the scientific wording
Energy drinks containing 240 mg of caffeine are associated with a greater negative impact on subjective sleep quality than coffee with the same caffeine dose, with 46.6% of users reporting poor sleep after energy drinks compared to 29.7% after coffee, suggesting non-caffeine ingredients may amplify perceived sleep disruption.
Ingredients in energy drinks besides caffeine stimulate the nervous system to stay more alert, making people feel like they slept poorly even when their actual sleep didn't change.
What the research says
1 studyPeople who drank energy drinks with the same caffeine as coffee said they slept worse—even though their actual sleep didn’t change. This suggests something else in energy drinks, not just caffeine, might make people feel like their sleep is worse.
