Blue light boosts alertness, making it wise to avoid screens well before bedtime. Recent research also links it to heightened appetite.
Light's Impact on Appetite
In a controlled study, participants felt hungrier just 15 minutes after blue light exposure. This effect lasted at least two hours, prompting them to eat more. Under dim lights, intake dropped significantly.
Limited but Intriguing Evidence
Conducted with only 10 participants, the findings aren't conclusive yet. Still, they suggest lighting influences eating—try dimmer ambiance for meals to potentially curb overeating.
