Several people I know talk about having sleep issues. One of the highly cited things of late is that the blue light from our electronic devices messes with our brains to reset the Circadian rhythm making us fall asleep later. Even I use f.lux to change the light of my computer to a warmer tone just after dark.
It’s tempting to believe that people these days aren’t getting enough sleep, living as we do in our well-lit houses with TVs blaring, cell phones buzzing, and a well-used coffee maker in every kitchen. But new evidence reported in the Cell Press journal Current Biology on October 15 shows that three ancient groups of hunter-gatherers–living in different parts of the world without any of those trappings of modern life–don’t get any more sleep than we do.
The most interesting thing is temperature appears to be the key to their sleep. As the temperature falls, people went to sleep and slept through the coldest part. When it started to warm up again is when they woke. A warm room temperature makes it difficult for me to sleep.
I think maybe we will see programmable thermostats offer an option to achieve bedroom temperatures that mimic the above temperatures so people can achieve their Paleo Sleep.
