What does your circadian rhythm say?

It’s always been clear that sleep is a big deal and more and more research is coming out to show the massive effect sleep can have in our lives. Especially at critical times of our development.

I have been tracking (quantifying) my sleeping solidly for about 3-5 years and its surprising to see the effect of the things like different alcohol drink, cheese, coffee, milk and chocolate. I also been to many events, with the last one being Cafe Sci: Myth and Science of Sleep. I generally track my dreams now, which is quite different from previously when I use to track them with a lot more detail.

Tracking sleep can seem a but of nonsense; I mean leaving your phone on your bed while you sleep or using a wristband device to collect data can seem poor for data collection. However with some calibration and a few months data, it becomes clear through the patterns whats good quality and bad quality sleep; oppose to the length of sleep. The key being the cycles of sleep… Light sleep into REM into deep sleep into light sleep and over again.

Sleep as Android data

Here is me sleeping in a hotel for 5hrs 49mins after drinking cocktails in London during the week of Mozfest. You can see the alcohol puts me into deep sleep quickly but it takes a while for my body to get back into its normal sleep pattern. I also had a done a lot of walking that day.

This clearly shows although I had 7hrs 21mins of sleep when I woke up, I felt like crap. To be fair I had red wine, and was on cold meds to get rid of my long lingering cold. Once again I was in a hotel, this time in Sarajevo. No coffee this time.

This is from todays sleep, even with a few scoops of ice cream and coffee, I slept extremely well and woke up feeling pretty fresh and ready to take on the world.

I use Sleep as Android with my Pebble watch. I do sync everything to Google Fit, Google Drive and Dropbox to make a personal back up for myself.

Ultimately I would clearly say I have learned so much by looking at the patterns, especially over a longer period of time.

Beware Philips Hue lights from the states

I bought into the Philips Hue system a while ago by buying the part I needed and then the lights afterwards. There are a tons of people selling the wired zeegbee bridge for as low as 25 pounds (I paid 26 for mine) then you can get a bulbs afterwards for much cheaper than the starter kit at 170 pounds.

So this is what I did…

Philips Hue Bridge

However I hit a problem, the first Philips Hue Lux light came and I could see it on the app via the bridge but couldn’t control it. I tried a lot of things including upgrading the system and rebooting the bridge. But it just didn’t response to anything I did. I thought well maybe its a dodgy bulb from ebay. However the next bulb came and I couldn’t even see it via the bridge.

I also ordered some via Amazon and they worked straight away, as expected!  I looked into the differences and found some bad news…

Philips will void warranty if 110V bulbs are used with 220V power and vice versa. Closer look at the packaging shows there maybe a problem.

Philips Hue Lux lights American packaging
The American Hue Lux – E26 bulb

Philips Hue Lux lights Europe packaging
The Europe Hue Lux – E27 bulb

So it looks like I have 2 American bulbs which I’ll have to put back on ebay at a lost (if it works at all?)

The good news is I have replaced my Philips Light/Wakeup clock with a Hue light which slowly turns on when Sleep as Android thinks its time to wake up. Apartment therapy you are wrong, using your phone as an alarm makes perfect sense, when used in the right way.
