Dr. Geri from Ideal You Weight Losss talks about blue light and its effects on your health In this health tips video.
Blue light is generated in many different ways, but this video will primarily be discussing the blue light generated by computers, tablets, smart phones and other digital devices. Blue light generated by these devices is intense and it creates a stress response in the user.
This stress response raises cortisol levels. Cortisol is a hormone that is triggered by stress and can lead to fat storage and weight gain amongst other health issues. An increase in cortisol also rapidly raises your blood sugar, which can lead to feelings of hunger and cravings for sugar and carbs.
You should try to avoid exposing yourself to blue light from all sources for at least one hour prior to going to bed. A lot of people don’t know that you primarily lose weight while you’re asleep and exposure to blue light right before or at bedtime has a negative effect on sleep and the ability to lose weight.
There are easy to find tools and tech available to help reduce our exposure to blue light like Night Shift for iPhones, or Flux or Iris software for your PC, and highly effective blue light blocking eyewear for nighttime use. If you notice, there is some blue in my glasses. This is for reducing the blue light during daytime when I’m in front of my computer. However, for nighttime use, you want to go for deep amber. This will help you to block all of the blue light and bring sleep on easily.
