Feel the Rhythm

I did a post on circadian rhythms a few years back and was recently reminded of how’ in today’s world, we can easily throw our rhythm out of wack. On the hunt for better sleep, and increased energy, I started paying attention to when I was letting blue light in after dark. I soon realized that late night tv watching and insta scrolling led me to a not so restful sleep. I decided to do my best of eliminating blue light after dark and start winding down when the sun goes down.

I try to avoid it as much as possible, but if I have to be on my computer or phone late at night, I have a blue light filter on my screens. You can  install f.lux on your computer and have night shift turned on your iPhone.

The health risks of nighttime light

Some studies suggest a link between exposure to light at night, such as working the night shift, to some types of cancer, diabetes, heart disease, and obesity. That’s not proof that nighttime light exposure causes these conditions; nor is it clear why it could be bad for us. But we do know that exposure to light suppresses the secretion of melatonin, a hormone that influences circadian rhythms, and there’s some experimental evidence (it’s very preliminary) that lower melatonin levels might explain the association with cancer.
