Dim evening lights
This helps reduce melatonin suppression and improves sleep efficiency.
What You'll Do
Dim the lights in your home to a warm color for the evening.
Scientific Basis
Evening restriction of ambient light improves sleep efficiency by 17%, promoting mood regulation through reduced circadian disruption.

High sensitivity of human melatonin, alertness, thermoregulation, and heart rate to short wavelength light. Journal of Clinical Endocrinology & Metabolism, 90(3), 1311–1316.The Science of Impact
Improving sleep efficiency can enhance overall mood and cognitive function, as sleep quality is linked to emotional regulation.
Reduced circadian disruption may lower the risk of mood disorders, with studies indicating a 30% increase in depressive symptoms associated with poor sleep.
Managing light exposure can lead to better sleep hygiene practices, contributing to long-term health benefits.
Pro Tips
Limit exposure to blue light from screens at least 2 hours before bedtime.
Use blue light-blocking glasses in the evening if screen use is necessary.
Install dim, warm-colored lighting in your home for evening use.
