Seeing the sunrise and sunset with your naked eye is vital for your circadian rhythm because it helps to regulate your body’s internal clock. Your circadian rhythm is the 24-hour cycle that controls various physiological processes in your body, such as sleep-wake cycles, hormone production, and metabolism.
Sunlight contains a spectrum of colors, including blue light, which is essential for regulating the circadian rhythm. When you expose yourself to sunlight, especially during the morning and evening, your eyes detect the blue light, which signals your brain to suppress the production of melatonin, a hormone that helps you sleep. This suppression of melatonin production helps you to feel alert and awake during the day and promotes better sleep at night.
In addition, seeing the sunrise and sunset with your naked eye can help to synchronize your circadian rhythm with the natural light-dark cycle of the environment. This synchronization can improve your overall health and well-being by promoting better sleep, reducing the risk of mood disorders, and improving your immune function.
Therefore, it is important to try to get outside and see the sunrise and sunset with your naked eye as often as possible, especially if you spend a lot of time indoors or work in an office with artificial lighting.
