How Blue Light Affects Our Health

Blue wavelengths which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night. At night, light throws the body’s biological clock the circadian rhythm out of whack. Sleep suffers. Worse, research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity.

Here are a myriad of ways how blue light from your phones and computer screens can affect your health :

  • Affects Memory – The disruption to your sleep schedule might leave you distracted and impair your memory the next day.
  • Affects Learning – A poor night’s sleep caused by smartphone light can make it harder to learn.
  • Build Neurotoxin – Over the long term, not getting enough sleep can lead to neurotoxin buildup that makes it even harder for you to get good sleep.
  • Depression – People whose melatonin levels are suppressed and whose body clocks are thrown off by light exposure are more prone to depression.
  • Increases Obesity Risk – By disrupting melatonin and sleep, smartphone light can also mess with the hormones that control hunger, potentially increases Obesity risk.
  • Harms Retina – There’s some evidence that blue light could damage our vision by harming the retina over time, though more research is needed.
  • Causes Cataracts – Researchers are investigating whether or not blue light could lead to cataracts.
  • Causes Cancers – There’s a connection between light exposure at night and the disturbed sleep that come with it and an increased risk of breast and prostate cancer.

Even if there are so many health effects of blue light, we can’t stop using electronic equipments. So prevention is better than cure. Use dim red lights for night lights. Red light has the least power to shift circadian rhythm and suppress melatonin. 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. Hope this helps.

  2. Sometimes I use a red light of I happened to get what looks like a pimple coming in. The SAL3 soap has overall kept the outbreaks in check. But if one slips through, the red light helps.

    • Yes manoj. by enabling night mode on your devices, you take away the blue light. This allows your brain to to go back to your natural circadian rhythms and help you fall asleep faster and deeper. Of course, avoiding using your devices before bed works too, but most of us are guilty of checking emails, Facebook, and other apps before bed. But anything in excess is bad. Limit your use of technology.

  3. Hey, really useful post. I have a question. What about the “night mode” that many mobiles bring to use? is that useful? The screen goes black and the letters white, but I don’t know if that helps to prevent all the things you’ve mentioned. Nice meeting you here!
