The Relationship Between Lighting and Circadian Rhythm
The Relationship Between Lighting and Circadian Rhythm
Our body’s natural sleep-wake cycle, or circadian rhythm, is largely influenced by light. The circadian rhythm is a 24-hour internal clock that regulates various bodily functions, including sleep and wakefulness. It responds primarily to changes in light and darkness, which signal the brain to release hormones that affect various bodily processes.
When we are exposed to natural daylight, our body releases cortisol hormones that help us stay awake and alert during the day. As the sun sets, our body begins to secrete the hormone melatonin, which helps us feel sleepy and fall asleep at night.
However, the use of artificial lighting, particularly blue light emitted by electronic devices, can disrupt this natural process. Blue light suppresses the production of melatonin, making it harder to fall asleep and affecting the overall quality of sleep. In contrast, warmer amber/red light has been shown to have less of an impact on circadian rhythm and may actually promote better sleep.
It’s important to be mindful of the type and amount of light that we’re exposed to, especially in the evening hours when we’re winding down for the night. Choosing warm, dim lighting and avoiding exposure to electronic devices can help support a healthy sleep-wake cycle and improve overall sleep quality.
To summarize, our body’s natural sleep-wake cycle, or circadian rhythm, is regulated by light and darkness, with natural daylight promoting alertness during the day and the hormone melatonin promoting sleepiness at night. Artificial lighting, particularly blue light from electronic devices, can disrupt this natural process and negatively affect sleep. Choosing warm, dim lighting and avoiding electronic devices before bed can help support a healthy sleep-wake cycle.
| Natural Lighting | Artificial Lighting |
|---|---|
| Helps regulate circadian rhythm and promote alertness during the day | Blue light from electronic devices can disrupt circadian rhythm and negatively affect sleep |
| Triggers the release of cortisol hormones that help us stay awake and alert | Supresses the production of melatonin, making it harder to fall asleep and stay asleep |
| Can improve mood and energy levels | Can lead to sleep disturbances and mood disorders like depression |
