What is the Circadian Rhythm?
Every day you wake up, go about your day (hopefully with energy…) and then night comes and you go to sleep, hopefully….This all happens in a day and is called the Circadian Rhythm. In other words, your body’s internal biological clock, and it's responsible for regulating your sleep and wake cycle.
It's what wakes us up in the morning, when the sun comes up, and makes us sleepy in the evening, when the sun goes down. As you can see, the amount of light in our environment has a direct impact on our body’s sleep and wake cycle.
Each organ and even each cell has its own circadian clock, but we also have a master clock whose job it is to keep it all in sync. This master clock is found in the suprachiasmatic nucleus (SCN), located in the hypothalamus, in the brain. It’s a complicated process but essentially what happens is the SCN receives direct input from the eyes. And what is entering the eye…light of course. And what is the best kind of light for our natural bodies…natural light from the sun. It contains the full spectrum of wavelengths, with all the colors in just the right balance to help our bodies function optimally. Not at all like artificial lights which have far too much blue and green light and not at all in harmony with red and orange light. More on the difference between natural and artificial light in a later post…
Back to the Circadian Rhythm and what you can do to optimize it. We need healthy doses of natural light every day for our body’s internal clock to function like it’s designed to.
Promise me you’ll do this tomorrow:
Watch the sunrise and sunset. This is how to reset your Circadian Rhythm for its daily cycle.

It’s likely you’ll notice immediate benefits, like more energy that day, even though you woke up early. Do this daily and the benefits will multiply – improved sleep, better brain function, higher productivity, and the ultimate goal longer term, protection from chronic diseases.
