Since we’ve embarked on the sleep challenge, I felt it relevant to cover a factor that may be holding some of you back from getting all the hours you possibly could. The very device you’re using to view this post, whether a laptop or an iPhone, emits blue light and that can be throwing off your internal clock. If you make a habit of watching TV in bed to fall asleep or browse the internet until you get drowsy, you may be making it that much more difficult to drift off into slumber. I became aware of my own poor habits after reading an article on Mark’s Daily Apple. After moving into my new apartment, I ensured that I would at least not have a television in my bedroom to avoid that potential pitfall. However I tend to spend time on my computer (for example, writing this post) until well close to my bedtime. As the article on MDA states:

Blue light regulates our secretion of melatonin, the sleep hormone. Exposed to blue light, we limit the production of melatonin, and we stay alert and awake; in the absence of blue light, melatonin production ramps up, and we get sleepy.

So aside from the obvious improvement of limiting TV or computer viewing prior to sleep, what else can we do? Well one of the suggestions is that red light, such as that emitted by a campfire, may help promote melatonin production and encourage sleep. One of the readers on MDR went on a 30-day experiment where they lit their home by candles only after sundown and noted a marked improvement in their sleep quality in addition to falling asleep almost 3 hours earlier. While I wasn’t up for totally eliminating all lights in my home, I did try going by the light of candles alone for about 2 hours before bedtime. I did find it much easier to fall asleep and slept quite deeply. Take a look at the full tips in the article, experiment with them and see if your own sleep improves!
