Waking up in the dark is my first sign that the seasons are changing. I'm not a big fan. It just seems natural that we should wake up with the sun. Light tells your body it's time to wake up.

To combat that there are daylight simulation alarm clocks that begin with a soft glow and ramp up to full brightness by your wake-up time. Imitating a sunrise in your bedroom can either positively affect the way your body responds to waking up or a royal pain in the butt.

I rarely use an alarm and naturally wake up at the right time. However, I'm less likely to when it's dark outside. Guess I'll be a little late to my morning meetings :-)
