Why Sleep Timing Matters

Changing the Clocks

Now, consider the spring-forward time change. Waking up an hour earlier than usual and getting your stove clock, car clock, and wall clocks all on the same rhythm. It’s just one hour and a few clocks, but it squeezes out a groan from most people every single season. It also heightens heart attacks and car accidents the day after (but that’s a topic for another time).

Synchronizing with the Sun

Here’s one last example of the relevance of sleep timing. What would it be like if the sun changed its rising and setting time throughout the week? What if it got dark at 7pm one night and 9pm the next, and wavered back and forth erratically in this way? Nobody would like it. It’s too unpredictable. And that’s exactly how the body feels (groan) about the internal changes made by external clocks night to night.
