After reading the Circadian Code, I felt like one of the biggest practical points I had learned that I had no idea about was what the article above captures in this paragraph:

A recent German study suggested that exposure to bright light in the morning boosted people’s reaction speeds and maintained them at a higher level throughout the day—even after the bright light had been switched off. It also prevented their body clocks from shifting later when they were exposed to blue light before bed.

Whereas a lot of the other points are readily available knowledge (if you stay away from bright lights or blue light later in the evening you'll fall asleep more easily), this little nugget is not well known and I've found that it makes a huge difference to my energy levels in the mornings when I actively look to spend some time in extra brightness in the mornings (though no difference noted at bed time).

@iteles why do you think I've been using an extra bright reading/work light first thing in the morning for so many years. It wakes me up long before the sun rises. 😉
