Every single cell in our body has a molecular clock, and those clocks are harmonized by the suprachiasmatic nucleus (SCN) which serves as the body’s master clock that helps regulate our circadian rhythm.
Circadian rhythm is an invisible, internal 24-hour clock of every person. The most important function of the circadian rhythm is the sleep-wake cycle. Studies show that the human body is the most hungry for sleep between 2:00 AM to 4:00 AM and most productive during the late mornings like 10:00 AM to 12:00 noon.
This master clock of the body is directly influenced by environmental cues, especially light, which is why circadian rhythms are tied to the cycle of day and night.
When the circadian rhythm is disrupted, it may lead to your body being prone to sickness.
Take a look at these warning signs that indicate if your body may be suffering from a disrupted circadian rhythm:
Sleeping problems like insomnia
Higher risk of dementia
Waking up too early or lack of sleep
More productive at night than during the day
Have an irregular sleep-wake rhythm
The concept of a circadian lighting follows that of a human circadian rhythm. The intent of this lighting design is to work in harmony with our internal clocks by providing ample access to daylight or, when daylight is unavailable, modulating the intensity, spectrum, and color of electric light in symbiosis with the natural lighting cycle. This balance should amplify occupant comfort and productivity and create a healthier visual environment and experience.
In addition to productivity, some studies suggest that circadian lights can increase occupants’ energy particularly at the start and middle of the day.
Circadian lights are like an artificial sunrise to sunset lights. The lights send signals to the master clock in our brains, telling our bodies when it is day or night time. Some workplaces invested in a circadian lighting system because they believed that it promotes and increases cognitive processing while lessening workplace errors as well.
In general, light has a significant effect on our body’s circadian rhythm. Increase the amount of light or brightness you’re exposed to during the day time if you aim to be more productive and limit light at night to have a peaceful and full rest. In order to get through our day’s work, it’s vital that we have healthy and correct circadian rhythms.
