What is the Circadian Rhythm?
AN INNER CLOCK
It is an internal clock in our bodies that makes us alert during the day and sleepy at night.
With exquisite precision, our circadian rhythm regulates critical functions such as behavior, hormone levels, sleep, body temperature and metabolism.
Wake in the day, sleep at night
Bright light is an important influence on our body. Too little light in the morning may cause us to feel tired during the day. Too much light at night may make us unable to fall asleep at bedtime.
When our internal body clock does not match our external environment or lifestyle, we do not feel good. This is why we feel sluggish when we travel across time zones and experience jet lag, or during long dark winter days.
Our modern way of life, where we sit inside our dimly lit office during the day and look at our screens on brightly lit devices at night, is disrupting our bodies’ natural clock. This causes us to feel tired and moody.

TIMING IS EVERYTHING
Our cognitive abilities don’t remain static over the course of a day. During the 16 or so hours we’re awake, they change—often in a regular, foreseeable manner. We are smarter, faster and more creative during some parts of the day than others.
With knowledge of our internal body clock, we can harness the power of bright light to be healthier and more productive.
