How Light Affects Your Health

Lighting for Wellness & Health

90% of our day is spent indoors, surrounded by static lighting systems and screens rather than natural light.

That’s a problem. Light—and especially natural shifts in light—is the number one component in setting our body clocks. These clocks, or circadian rhythms, tell our bodies when to wake and sleep and are important to good health. Light is inextricably bound to vital functions like hormone production, metabolism, and sleep/wake cycles.

Healthy light is bright during the day to energize our minds and set our body clocks. At night, it dims so it doesn’t disrupt our sleep cycles. Sadly, most lighting is designed only for energy efficiency, making it too dim in the daytime and too bright in the evening. That’s why a healthy solution requires circadian lighting—light that evolves over the course of a day.

Receiving the right light at the right time can positively impact our mood and productivity. Studies show that bright morning light is correlated to improved mood, productivity, and even sleep quality. Morning light plays a vital role in stimulating the release of cortisol, which prepares us for periods of activity.

By contrast, unnatural static light has been shown to disrupt our circadian rhythms and, therefore, our sleeping patterns, heightening our risk of serious health consequences.

Light and Melatonin

Every evening, the hormone melatonin activates sleep and other nighttime processes in our bodies. Melatonin is a primary contributor to our health.

Research shows that light tells the body when to secrete and suppress melatonin. Too much light in the evening can advance the circadian clock, making it more difficult to fall asleep. Awareness of the impact of evening light is why leading device manufacturers have implemented night shift mode on phones and tablets.
