Blue Light, The Outdoors & Sunlight

Sunlight Outdoors On The Beach. Sunlight & Blue Light

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 Outdoors On The Beach. Sunlight & Blue LightSunlight 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 human and animal sleep cycles known as the circadian rhythm. It’s linked to every part of us, our metabolism, alertness even our mood and mental state. Have you had a stressful day? A short walk in the park or spending time outdoors can completely change how you think and feel, and this is partly due to sunlight.

Blue Light, Sunlight & The Light Spectrum

Many of us do not realise the light emitted by our sun has all the colours of the rainbow. Each colour has a different amount of energy and capability to impact us as humans. Sunlight contains a range of colours, red, orange, yellow, green and blue light, each of these with their specific energy and wavelength (called electromagnetic radiation). When we combine all these colours, we get “sunlight” or “white light”.

Science has proven that the colour we see (or cannot see) links to the wavelength, and this is linked to the amount of energy each colour contains. Long wavelengths, such as those found in the colour Red, has less energy while Blue’s which have shorter wavelengths have more energy. So while we are all cautious about UV light and its damaging effects on our skin and eyes, it sits back to back with Blue Light.

We hope this article clears up where Blue Light sits on the light spectrum. If you want to read more about the damaging effects of blue light, please follow this link: Is Blue Light Dangerous.
