The Claim
Among employed adults, 71.7% report poor sleep quality (PSQI ≥5), which is higher than general population estimates of 15–50%.
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.
Among working adults, 71.7% have poor sleep quality based on standard measurements, a rate higher than the 15–50% seen in the general population.
See the scientific wording
Among employed adults, 71.7% report poor sleep quality (PSQI ≥5), a rate substantially higher than general population estimates of 15–50%, suggesting that employment-related factors such as stress, schedule, or lifestyle may significantly impair sleep.
Caffeine blocks signals in the brain that tell the body it is time to sleep, which prevents deep sleep from starting and causes frequent awakenings during the night, leading to poor sleep quality.
What the research says
1 studyThis study found that working adults who drank more coffee or tea tended to sleep worse, and over 7 in 10 of them had poor sleep — which matches the claim. It suggests that caffeine, often consumed because of work demands, might be one reason why workers sleep so poorly.
