What is blue light and how is it affecting my health?

Although it is environmentally friendly, blue light can affect your health. Until artificial lighting became easily attainable, the sun was the major source of light, with people spending their evenings in (relative) darkness. Now our evenings are illuminated, but is our health paying the price?

At night, light disrupts the body’s biological clock, our Circadian Rhythm. This means our sleep suffers and worse, research shows that it may contribute to cancer, diabetes, heart disease, and obesity.

What is blue light?

Blue light is beneficial during daylight hours because it boosts attention, reaction times, and mood. However, being exposed to blue light at night blocks melatonin production; this is the hormone responsible for your Circadian Rhythm (your sleep-wake cycle). Many people are aware of the blue light in screens, but not many people know about the blue light spike in standard LED lighting. So our exposure to blue wavelengths is increasing, especially after sundown.

RAY and Blue Light

For the SunRAY range, the internal chip or light source within the lightbulb harnesses new technologies that avoid the dangerous blue spikes that occur from standard LED lamps, bringing levels of blue in better balance with those naturally occurring in nature. This delivers instant benefits for our Circadian sleep/wake rhythms and associated sleep, moods and physical responses, since we are no longer overstimulating the brain.

Protect yourself from blue light at night:

  • Invest in RAY's healthy lighting range;
  • Use dim red lights for night lights. Red light is less likely to shift circadian rhythm and suppress melatonin;
  • Avoid looking at bright screens beginning two to three hours before bed;
  • If you work a night shift or use a lot of electronic devices at night, consider wearing blue-blocking glasses or installing an app that filters the blue/green wavelength at night;
  • Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night, as well as your mood and alertness during daylight.
