The human body is amazing. It operates like a finely-tuned machine, with each part playing a crucial role in our overall health and well-being. One of the key components that keep our body running like a well-oiled machine is our circadian rhythm. This 24-hour internal clock regulates our sleep-wake cycle, hormone production, eating habits and overall health. Interestingly enough, what you expose your eyes to can make all the difference when it comes to regulating this vital function. In this blog post, we'll dive deep on why light exposure is critical to our circadian rhythm.

First and foremost, it is essential to understand what the circadian rhythm is and how it works. Our body has an internal clock, which regulates numerous physiological functions, including sleep. The internal clock responds to cues from the environment to determine whether it's time to be awake or asleep. One of the most crucial external cues our internal clock responds to is light exposure.

Light exposure affects the circadian rhythm by influencing the production of the hormone, melatonin. Melatonin helps regulate the sleep-wake cycle. When it's dark, our body naturally begins to produce more melatonin. Whereas, when it's bright or light out, our body produces less melatonin. This is why it is essential to expose yourself to bright light during the day and avoid exposure to blue light at night.

Blue light during nighttime can reduce the production of melatonin and trick our body into thinking it's still daytime. This has led to significant disruptions in sleep patterns and ultimately leads to fatigue and exhaustion. Studies have made it clear that natural light exposure during the day is crucial for good overall health and well-being.

A recent study conducted at the University of Colorado found that being exposed to natural light, rather than artificial light, provided a more substantial boost in well-being. The study also revealed that people who spent more time in natural light had better sleep quality, physical activity levels, and vitamin D levels.

One of the most significant signals our internal clock receives is the intensity of light exposure. In the morning, natural light is generally more intense, and this helps reset our internal clock, allowing us to wake up more easily. By being exposed to natural light in the morning, we're less likely to feel groggy and more likely to feel energized and alert.

In summary, the importance of exposing yourself to good quality light during the day cannot be overstated. The type of light and its intensity will significantly affect your body's internal clock and ultimately, your overall health and wellness. Simply by being mindful of your light exposure, you can vastly improve your circadian rhythm, sleep, and overall well-being. Next time you step outside, take a deep breath, and soak in some natural light. Your body and mind will thank you!
