What You Should Know About Your Circadian Rhythm


You’ve probably heard of the term “circadian rhythm” and know that it relates to your body’s sleep cycle. However, to give you a better understanding of this concept, we’re taking a closer look at how exactly the circadian rhythm works and everything you should know about yours. 

In simple terms, your circadian rhythm is an internal clock that tells your body when to be awake and when it’s time to sleep.

This rhythm is controlled by a part of the brain called the hypothalamus. The circadian rhythm is also affected by light; when it’s dark outside, your brain signals your body to produce melatonin, which induces sleep. 

Your circadian rhythm can be disrupted by overexposure to bright lights. Bright screens keep our eyes alert and prevent our brain from signaling the body to produce melatonin. A disrupted circadian rhythm leads to lack of sleep, fatigue, and loss of focus. 

The best way to maintain a healthy circadian rhythm is to keep regular sleeping habits. In addition to having a routine when it comes to the time you wake up and go to sleep, avoiding bright screens and lights before going to bed is essential. 

Turning your digital devices on “night mode” can stop your eyes from straining behind bright lights. Even more beneficial than switching on “night mode,” however, is wearing a pair of blue light blocking glasses. 

Blue light blocking lenses block lights emitted from digital devices, television, and artificial LED lighting that signal our brain to stay awake and prevent our body from producing melatonin.

By protecting your eyes from harsh lights that disrupt your circadian rhythm, BluTech lenses can help increase your production of melatonin, resulting in a better night’s sleep, less fatigue, and improved productivity.
