Blue Light, Depression & Anxiety

A Harvard study identified preliminary results that link blue light to diabetes and possibly obesity. The researchers put ten people on a schedule that gradually shifted the timing of their circadian rhythms similar to what occurs when you look at a screen or mobile phone. The test subject's blood sugar levels increased, placing them into a pre-diabetic state. Their levels of leptin, a hormone that keeps people feeling full after a meal, went down. Here's a link to the Harvard Study: Link Here is why. Nighttime exposure to blue light delays the nocturnal melatonin peak (shifting the circadian rhythm) which

Blue Light & The Immune System

While we sleep, our immune systems release sleep-promoting proteins/peptides called cytokines. The body requires specific types of cytokines to increase if you’re feeling stressed, have an infection or inflammation. Cytokines act through receptors and play an essential role in the immune system. They are moderating the balance between humoral immunity (release of antibodies that rapidly respond against toxins) and cell-based immunity (release of cytokines that permanently act against disease-causing virus/bacteria. Cytokines also regulate the maturation, growth, and responsiveness of other cell populations that respond to trauma, sepsis, cancer and reproduction. The production of these infection-fighting antibodies and cells slow down

Blue Light, The Outdoors & Sunlight

As you step outdoors into the sunlight, the human eye is exposed instantly to several visible and invisible light spectrum's. Blue light and UV light is the most known of these spectrums; they enter our body through the eyes and skin. Initiating chemical reactions in our bodies both inside and outside. A well-known example from UV light is sunburn.Sunlight is part of the human race and has been for millions of years, like most animals on planet Earth. It plays an essential role in our survivability as well as being a major contributing factor in the global ecosystem. Sunlight synchronises

Blue Light Blocking Glasses & Sleep

Before the invention of light bulbs, the human circadian rhythm was entirely in sync with the sun because night time light disruption was minimal. At night, exposure to devices emitting blue light is harmful to sleep and the circadian rhythm (the body's biological clock). Research has proven that Blue Light prevents body temperature from dropping during the night. A slowly decreasing body temperature is a critical process to which the body progresses into the stage of sleep. Blue light keeps the body temperature elevated at day time levels. Studies show that exposure to blue light, even when dim, can suppress
