1. Cortisol

Cortisol should peak between 6:00am – 8:00am. Low cortisol in the morning results in low energy and trouble getting going for the day. High cortisol at night can be caused by poor food selection, stimulating TV shows, and exposure to bright lights and may affect sleep negatively.

2. Melatonin

If cortisol is elevated at night due to blue light exposure, melatonin won’t be produced or will be produced to a lesser degree.

3. Natural Rhythm

Create a natural rhythm using blue lights in the morning and reducing/eliminating blue light exposure in the evening. This rhythm will help produce healthy levels of cortisol in the am and normal levels of melatonin in the evening.
