How Your Smartphone, Tablet, and Laptop is Affecting Your Sleep

I don't know about you, but I'm pretty much a slave to my smartphone. It's pretty much the last thing I look at before I go to sleep, and the first thing I reach for when I wake up. I'm trying to spend less time on it, but I must admit that it's quite difficult! There's constantly something going on in the world, and the web is what keeps you in touch! But did you know that this wonderful tool could be what's keeping you awake at night and interrupting your normal cycle of sleep?

Basically, blue light emitted from your smartphone, tablet or laptop is interrupting your internal clock and telling your body that it's morning and that it isn't time to sleep yet. 

Recently, Dan suggested I download a program called f.lux onto my laptop. It is a program that automatically changes the colour of your screen based on what time it is. In the morning, it emits the regular blue light that tells your body that it's morning and the sun is shining. Get out and do some work! Then, at night, it changes so that more red light is emitted, telling your body that it's dusk and it's time to wind down and get some shut-eye. How does your body recognize these signals? Check out this video to find out.

 

 

Sleep well and be healthy!
