How Has Blue Light Affected My Sleep and Eczema?

“Anti-blue light” is a term used to describe measures taken to limit exposure to blue light. But what exactly is blue light, and how does it relate to eczema?

What is blue light?

Blue light is a component of the visible light spectrum that we encounter daily.1 It’s the reason why the sky appears blue and is also emitted by digital screens.2 This type of light can be harmful if we’re exposed to it excessively, especially without the balance of other types of light, such as amber light.3

How does blue light affect circadian rhythms?

Our sun emits different types of light throughout the day as the Earth rotates, giving us morning, afternoon, and night.2 These varying light spectrums contribute to our circadian rhythm, which is our body’s natural sleep-wake cycle. Overexposure to blue light, particularly during late morning or midday, can disrupt this cycle by signaling the body to stay awake.1

What effect can it have on eczema?

If the body doesn’t get enough rest due to disrupted circadian rhythms, it can potentially exacerbate conditions like eczema.4 Therefore, managing our exposure to blue light is crucial not only for maintaining our sleep health but also for managing conditions like eczema. That is why we need these kind of sunglasses to help.
