However, what many do not know is that LED light, present in lamps, lamps, public lighting, as well as on TV screens, monitors and smartphones, come with some health risks if used in excess.
After all, what is the impact of LED lights on health?
Common types of LED lights carry higher proportions of blue wavelengths. In short, blue light is known for its stimulation of melanopsin production, a hormone in our eyes that promotes alertness.
On the other hand, artificial blue light affects the production of melatonin, a hormone that regulates our sleep. Therefore, when exposed, it is as if our brain understands that this is not the best time to rest, impairing the quality of our work.
sleep.The electronic devices we use, such as smartphones and computers, emit vast amounts of blue light. Prolonged exposure to it, especially at night, can also have adverse effects on the circadian rhythm, in addition to impairing sleep, as mentioned above.
According to studies, constant exposure to blue light over time can damage retinal cells and cause vision problems. It can also contribute to cataracts and eye cancer.
Beforehand, it is worth noting that the natural blue light of the sun during the day is beneficial for our brain by helping to regulate our biological clock.
How can I reduce the impacts?
In short, to avoid being affected by blue light, you can -and should- resort to lower temperature bulbs (2700k or lower) (experts recommend 2400k). Also, when you're wanting to sleep, resorting to warmer colors will make the impacts less.
Regarding the use of devices, it is recommended to activate the blue light filter. Several smartphones come with the feature. Check.
Finally, get regular checkups with a specialist to check your eye situation. Always remember that in situations of prolonged exposure involving the use of devices with blue light, the use of glasses is preferable.
