Blue Light; Dangerous or Not

What is this blue light that is making headline news recently?
Quite simply it is a source of wave length that is associated with computer screens and mobile phones and as you can imagine we are getting more exposed to them in today’s world with modern technology.

Blue wavelengths are beneficial during the day as they help to boost attention and mood, however they are clearly disruptive at night as the light throws the biological clock into disray and this isn’t great if you already struggle with sleep. Artificial lighting and light exposure suppresses the secretion of melatonin which then in turn has an affect on your circadian rhythm

Even worse, research into blue light states there may be links to the cause of cancer, diabetes, heart disease and obesity.

While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully according to Harvard researchers.and their colleagues whom have been conducting many experiments.

If blue light does have adverse health effects, then environmental concerns, and the quest for energy-efficient lighting, could also be at odds with our personal health. Those curlicue compact fluorescent light bulbs and LED lights are much more energy-efficient than the old-fashioned light bulbs we once knew, but they also tend to produce more blue light

So what can you do to start protecting both yourself and your children from the dangers that are being linked with blue light;  here are three top tips that are strongly recommended

  • Avoid looking at bright screens approximately 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.

I hope you have found this helpful, feel free to share and if you have any concerns regarding your children and technology these days, please comment I would love to connect. Alternatively connect with me via (linktr.ee/shaz_crowley)
