The Claim
Sleep deprivation and nocturnal blue light exposure disrupt circadian hormone regulation, resulting in a 15-20% reduction in circulating leptin concentrations and impaired insulin sensitivity and hunger signaling.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Not getting enough sleep and being exposed to blue light at night messes up your body's internal clock and hormone balance. This causes your hunger-regulating leptin levels to drop significantly and makes your body less responsive to insulin, which can increase your appetite and affect your metabolism.

Sleep deprivation and nocturnal blue light exposure significantly disrupt circadian hormone regulation, reducing circulating leptin concentrations by 15-20% and impairing insulin sensitivity and hunger signaling.
What the research says
1 studyStudy: Kurang Tidur dan Regulasi Nafsu Makan: Tinjauan Mekanisme Hormonal dan Metabolik
The study confirms that not getting enough sleep lowers the fullness hormone and makes your body less responsive to insulin, which matches the claim, though it does not mention blue light.
