How to limit exposure to “Blue light” and Improve Family  Sleep.

All of our lives have been turned upside down in the pandemic. Many parents and young people are reporting disturbances in sleep patterns. As a result of social isolation, fears regarding the virus, and an increase in working online, you and your children are exposed to “blue artificial light” from increased screen use. This in turn will affect everyone’s sleep!. Now more than ever we need sleep to remain healthy.

What do you mean by Blue Light?.

What did we do prior to artificial lighting?. The sun used to be our primary source of light and we spent most of the evenings in the dark. Hence, our pineal gland secreted melatonin and we stayed in alignment with 24 cycle ( Circadian Rhythm). During the pandemic, all of us are staring back at screens and our homes are full of LED lights that emit blue light. Being exposed to blue light all day throws out our alignment with our Circadian Rhythms. This contributes to sleep difficulties and diseases such as diabetes and obesity. In children, it also leads to multiple difficulties ranging from shorter attention span, impaired cognitive difficulties, behavioural and emotional problems. For more information, go to this blog.

Dangers of Blue Light.

Here are the dangers according to a Harvard Study. They found that suppresses melatonin twice as long as the green light, shifting circadian rhythms by twice as much (3 hours versus 1 1/2 hours). this means in takes longer to go to sleep. In addition exposure may be linked to other diseases such as:

How you can incorporate Natural Sunlight into your Day.

Working Natural Daylight into Your Day

  • Spending time in the sun in the morning is a great way to help reset your and your child’s circadian rhythms.
  • Going for a 30 minute morning walk or sitting in the garden while reading or eating breakfast are great ways to incorporate daylight in the morning. Open up the windows and blinds on days when morning walks are not as easy to fit in.
  • Getting outside in the afternoon is another great idea to get a little more exposure to sunlight. A park date or another 30 minute stroll will do wonders for your child’s sleep.
  • Something else to remember when encountering the daylight. Sunlight should also have direct contact with your eyes ( you don’t need to directly look at the sun) in order for your brain can register the light, so make sure to take those sunglasses off during your outdoor encounters.
  • Always take a break if you are home working. I go out everyday between clients to receive a dose of sunlight.

A Common Question?.

What if it is an overcast day and the sun is not out?

Still make sure to get outside! Even when filtered through clouds, the sunlight will continue to have an impact on our circadian rhythms.

How to Manage Blue light in your Home.

  • Get rid of LED lights and replace them with lights on the amber or red spectrum. LED lights amplify blue light, hence, lack many of the frequencies of natural light.

  • Keep your screens (computer, phone, tablet) as dim as you comfortably can. You can train yourself to use less and less.
  • If you have an iPhone, use the Night Shift feature. It will detect the time of day and adjust your screen accordingly.
  • For Android users, get the f.lux app or something similar.
  • Download the f.lux app for your computer too. It’s free. Your screen will turn more amber when the sun goes down. You won’t have to think about it.
  • Ensure you or your child has no exposure to screens at least an hour prior to bedtime.
  • You can wear blue light blocker glasses, I have not tried this yet, however, some of the parents I work with do and found them helpful.
  • Sleep in total darkness, any light in our bedrooms seems to confuse our pineal glands. In addition, ensure that your children’s nightlights have no LED lights inside.

In Conclusion.

All the evidence supports that making a regular sleep routine with a consistent wake time, along with exposure to sunlight, is an extremely powerful combination when it comes to healthy sleep. if your child is anxious, do read the blogs below for more information on sleep and anxiety. Stay safe and well during this time.

Thank you for taking the time to read this and for your commitment to the wellbeing of your child and family. In addition, your willingness to keep growing and holding hope.
