Every individual has unique physical, mental, and behavioral changes that follow a daily cycle called circadian rhythm. Circadian wellness describes how well tuned your body’s biological clock (or circadian rhythm) is to the 24-hour sleeping and waking cycle. Since light is a major driver of circadian rhythm (i.e. sleeping at night and being awake during the day), it is paramount to control lighting conditions in order to protect an individual’s circadian wellness.
Chronobiologists have found that circadian rhythms are found in most living things, including animals, plants, and many tiny microbes.
Do you frequently wake up feeling groggy? Conversely, are you unable to fall asleep and stay asleep? Issues surrounding sleep are often a strong indicator that an individual’s circadian wellness needs improvement. One way light acts as a driver of circadian rhythm is to indicate to your body when and how much melatonin to produce. Light, especially light mimicking daylight conditions, causes your body to make less melatonin, while darkness increases melatonin production. Melatonin helps your body fall asleep and stay asleep . So if an individual is living in an environment with insufficient lighting conditions, their melatonin production and circadian rhythm can be thrown off balance.
Other circumstances that affect melatonin production and that disrupt circadian wellness include:
