Concerns over exposure to blue light has predicated several solutions to decreasing blue light exposure, including disabling or attenuating blue LEDs in displays, color shifting displays towards yellow, or wearing glasses that filter out blue light.
Exposure to blue light at night suppresses melatonin production, tricking the brain into thinking its still daytime. Research, including Dr. Narains studies at South Bay Retina, shows that evening blue light exposure delays melatonin release, shifts the circadian rhythm, and reduces sleep quality.
Research demonstrates that two-hour exposure to blue light at 460 nanometres in the evening suppresses sleep-promoting signals by 30 to 55%.
Such details provide a deeper understanding and appreciation for Evening Blue Light Exposure.
Exposure to blue light in the evening can markedly disrupt your sleep patterns by interfering with your bodys natural circadian rhythm. This happens mainly through melatonin suppression, which delays sleep onset and reduces sleep quality.
I once stayed up until 2 a.m. working on a project under bright LED lights, only to toss and turn until dawn. A study published in the Journal of Clinical Endocrinology & Metabolism found that just two hours of evening blue light exposure can reduce melatonin levels by up to 22%.
As we can see from the illustration, Evening Blue Light Exposure has many fascinating aspects to explore.
Blue light is a wavelength found naturally in sunlight, but electronic devices and some lightbulbs have increased our exposure to this light. Blue light could be bad for our eyes, but it is also beneficial for our health. Learn the facts and myths about blue light.
Blue light counts more, but it's your total exposure that makes the real difference. It turns out the solution starts the moment you wake up. Every morning during my test, I sat in front of a lamp that looks like a prop from a 1980s science fiction movie.
Use the Blue Light Free Evening Light for ambient illumination. Put on your AfterDark glasses if using screens or if you're in spaces with lighting you can't control. Use red light task lamps for reading, cooking, or focused work.
