Since I first tested sunrise alarm clocks last winter, I’ve come to suspect that there’s no such thing as getting up on the wrong side of bed. What we ought to be worried about is waking up on the wrong side of dawn.
During summer (and other times of the year, for late risers), the sunrise begins to rouse us before we wake up. The brain kicks into gear and sends signals to initiate all sorts of bodily processes, from metabolism to hormone release, which helps us to feel ready for the day. It’s a fundament of our circadian rhythm – and we miss out on it whenever we wake before it gets light.
