Did you know that…
That means you are exposed to artificial blue light at night.
Now what is blue light ?
Light is made up of particles that travel in waves which emit energy. These particles range in length and strength for example the shorter the wavelength the higher the energy, and the longer the wavelength the lower the energy. Wavelengths of light are measured in nanometres (nm) and each wavelength range is a different colour as the graph shows.
BUT WAIT.. There are two different categories of BLUE LIGHT
Natural Blue Light vs Artificial Blue Light
🔆 NATURAL BLUE LIGHT 🔆
When you go outside blue light is emitted from the sun. Blue light from the sun is essential in regulating your sleep and wake cycles and your body clock. Blue light has also been shown to improve alertness, reaction times and create a sense of wellness. Blue light from the sun is essential. Blue light from the sun is also accompanied by all the other colours from the light spectrum, making it a balanced and healthy light source. In winter months when the sun does not come out we can suffer from Season Affective Disorder (S.A.D) which lowers mood and heightens feelings of depression and anxiety.
📲 ARTIFICIAL BLUE LIGHT 📲
Blue light is also found artificially from electronic devices which include your smart phone and computer screens, as well as from light bulbs.
DARK SIDE OF BLUE LIGHT
We know that the shorter the wavelength of light the higher the amount of energy it contains. Blue light found at the very beginning of the visible light spectrum meaning it contains intense amounts of energy. Blue light ranges from 400-495nm.
The light found in digital devices and light bulbs contains far more blue compared to other colours in the spectrum meaning our eyes are receiving too much unbalanced blue light. This blue light penetrates the eye and over the course of a day will cause digital eyestrain. Digital eyestrain is characterised by dry itchy eyes, headaches and fatigue. Digital eyestrain can also progress into macular degeneration over time. In winter, the sun does not come out as much as the summer months which leads us to use more artificial light sources. This contributes to S.A.D by keeping our cortisol levels (stress hormone) chronically high as excessive blue light raises your stress hormones. Coupled with lack of sunlight this can lead to stress, anxiety and depression
>> So, if you are wishing to sleep well and be healthy you could consider buying the blue light blockers
As a personal suggestion, I recently purchased blue light blocking glasses from BLUBLOX and they really WORK!!!
