In the past weeks I have been working late on my laptop and was waking up feeling very tired the next day, although my diet, my exercise or my stress was not higher. It did not make any sense to me until I found the research on blue light. Convinced by this I installed a new software on my computer and started to sleep better at night.
If you are working late at the night on your computer, you should consider getting Justgetflux software. It will reduce glare based on the time of day, and protect your eyes from the blue light of the computer screen. It might also improve your sleep since exposure to blue light 30 min before bed is linked to poor rest quality. Plus it’s totally free.
Red light seems to be far less damaging for our eyes and our sleep so consider installing them in your bedroom. It will also make the atmosphere more romantic so you will not be only healthy but also happy, maybe that is why most of the clubs in Germany have red lights.
If you do not have a red lamp in your room, you can always get some glasses designed especially to reduce glare. (20$ on amazon).
After implementing this changes a significant number of people said they reported sleeping better, having less headaches and having more energy.
But why is everyone talking about how damaging blue light exposure is for our sleep and our bodies? For instance a sleep doctor says that even very young kids are suffering from chronic insomnia, and another scientist found out that women who work night shifts are twice as likely to develop breast cancer than those who sleep at night.
What is the common link? Nighttime exposure to the blue light from our screens.
Being in the presence of light at night disrupts the body’s natural circadian rhythms by suppressing the production of melatonin, a sleep hormone. But melatonin does far more than help us get sleepy – it’s also an antioxidant that appears to play a pivotal role in slowing the progression of cancer and other diseases. The impact of blue light on melatonin production was only recently confirmed, in 2001, when scientists found that light in the blue spectrum — the 415 to 445 nanometer range — disrupts melatonin. Because it is so bright, blue light is used widely in pretty much all LED devices, including phones, tablets, laptops, and TVs.
– Definition: Melatonin is a hormone found in animals, plants, fungi and bacteria in anticipation of the daily onset of darkness. It is synthesized in animal cells directly from the amino acid tryptophan, but in other organisms through the Shikimic acid pathway. In animals, melatonin is involved in the entrainment of the circadian rhythms of physiological functions including sleep timing, blood pressure regulation, seasonal reproduction and many others.
