1. Circadian Rhythms and Energy:

Recognize that circadian rhythms govern sleep-wake cycles and align with natural light patterns.

2. Morning Light Exposure:

Prioritize exposure to morning sunlight, which suppresses melatonin and enhances wakefulness.

3. Managing Light Exposure:

Integrate outdoor breaks or near-window time for natural light exposure. Limit evening screen time to preserve sleep quality.

4. Adjusting Light for Shift Workers:

For those with non-standard schedules, manage light exposure to regulate

Understanding the influence of light on your internal clock can significantly impact your energy levels and overall well-being.
