The Impact of Light on Sleep Quality
Bright lights at night can negatively affect sleep quality by reducing melatonin levels and increasing cortisol levels. Using blue-green light blocking glasses can help mitigate these effects, facilitating a smoother transition to sleep. Additionally, dimming lights in the evening is recommended to promote better sleep. This practice, alongside wearing appropriate eyewear, can significantly enhance sleep quality.
