Best Relaxing Light Colors to Improve Sleep Quality

Understanding Light's Impact on Sleep

The science behind light and sleep cycles

Our sleep-wake cycle, also known as the circadian rhythm, is profoundly influenced by light exposure. This intricate biological process is regulated by the suprachiasmatic nucleus (SCN) in our brain, which acts as our body's internal clock. When light enters our eyes, it stimulates the SCN, triggering a cascade of hormonal changes that affect our sleep patterns.

The primary hormone involved in this process is melatonin, often referred to as the "sleep hormone." Light exposure, especially blue light, suppresses melatonin production, keeping us alert and awake. Conversely, darkness stimulates melatonin release, signaling to our body that it's time to sleep.

How different colors affect our circadian rhythm

Different light colors have varying effects on our circadian rhythm due to their distinct wavelengths:

1. Blue light: Has the strongest impact on melatonin suppression

2. Green light: Moderately affects melatonin production

3. Red light: Has the least effect on melatonin and circadian rhythm

Here's a comparison of how different light colors affect our sleep-wake cycle:
