Your internal clock, also known as your circadian rhythm, enables your body to automatically know when to wake up and get out of bed and when it’s time to go to sleep, eat, and even ovulate. It also plays a major role in how productive and focused you are.
Here’s a quick primer on how this fascinating system works, why it gets messed up, and how to optimize it so you can go through every day feeling energized (and sleep through every night feeling restored).
OK, so what’s the circadian rhythm?
The circadian rhythm is the biological mechanism that controls the sleep-wake cycle, when hormones are released for ovulation and digestion, and when it is time for your body to sleep so that your muscles can rest, your memories can consolidate, and your immune system can get stronger.
Just like the ebb and flow and rhythm of nature, your body also needs this internal clock to operate with the natural rhythm of the earth to maintain good mental clarity and healthy moods, heart function, stress levels, and immunity.
These crucial processes for your health and well-being are largely tied to the the natural light that comes from the sun’s rays that is picked up by the suprachiasmatic nucleus (SCN) in your brain.
When sunlight comes in through the eyes, the SCN picks up the cue that it’s daylight and time to get up and be active. As the light diminishes and then disappears, the clock signals the body that it is time to sleep.
Every 24 hours, the clock is reset as sunlight comes through. In addition, genes, or “clock genes” found in every cell of your body, also influence this rhythm, regulating physiological processes like energy metabolism, immunity, and memory formation. [ … ]
