Circadian Rhythm

Circadian Rhythm: Your Body’s Internal Clock

The human body operates on a roughly 24-hour cycle known as the Circadian Rhythm. This internal clock regulates our sleep-wake cycle, feeding patterns, hormone production, and even brain activity. It is intrinsically tied to the Earth’s rotation, with our bodies responding to the cycle of daylight and darkness.

Light plays a crucial role in regulating our circadian rhythm. Exposure to light during the day helps us stay alert and awake, while darkness signals the body to produce melatonin, a hormone that promotes sleep.

Blue light, emitted in large amounts by electronic devices such as computer screens, can disrupt this natural rhythm. The high energy and short wavelength of blue light can trick our brains into thinking it’s daytime, even late at night. This can delay the production of melatonin, disrupt our sleep, and lead to various health issues, including insomnia, fatigue, and even certain metabolic disorders.

Blue Light Blocking Glasses are designed to filter out this disruptive blue light. By reducing your exposure to blue light in the evening, these glasses can help maintain your natural circadian rhythm, promoting healthier sleep patterns and overall well-being.

Research has shown that people using blue light blocking glasses reported better sleep quality and mood. The impact of blue light on our circadian rhythm is a growing field of study, with ongoing research underscoring the importance of protecting our eyes from excessive blue light exposure.
