The Claim
In healthy young women, consuming dinner 1 hour before bedtime is associated with a 2.3-fold higher Arousal Index and a 25.4-unit increase in Stage-Shift Index compared to consuming dinner 5 hours before bedtime, indicating increased nocturnal arousal and sleep fragmentation.
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.
In healthy young women, eating dinner one hour before bed is linked to more frequent awakenings during sleep and more transitions between sleep stages compared to eating dinner five hours before bed.
See the scientific wording
In healthy young women, eating dinner 1 hour before bedtime is associated with increased nocturnal arousal and sleep fragmentation, as evidenced by a 2.3-fold higher Arousal Index and a 25.4-unit increase in Stage-Shift Index compared to eating dinner 5 hours before bedtime, suggesting disrupted sleep stability.
Eating dinner close to bedtime causes blood sugar to stay high during the night, then drop quickly. This sharp drop activates the body's stress response, which wakes the brain briefly and causes frequent shifts between sleep stages, breaking up sleep.
What the research says
1 studyThis study found that when young women ate dinner just one hour before bed, they woke up more often and switched between sleep stages more than when they ate dinner five hours before bed — meaning their sleep was more broken and less restful.
