HOW TO BECOME A MORNING PERSON!

If you work out early in the day, you know, before 8 or 9:00 a.m., it's going to accelerate that increase in body temperature and you'll feel more alert.

There's also this beautiful phenomenon in circadian biology called entrainment, whereby, let's say you're not a morning person.

You hate mornings, if you force yourself to get up and exercise at say 6:00 a.m. for three days in a row, by the fourth day, you'll naturally start waking up around that time.

Because the circadian clock of the brain, we call the superchiasmatic nucleus, the main inputs that drive when you're alert and when you want to be asleep.

Are sunlight exposure to the eyes, this is the whole basis for that morning sunlight exposure, physical activity, when you eat, and social engagement.

And there could be a whole discussion about this, but suffice to say that if you start getting some morning light, some exercise, maybe even before the sun comes out, some caffeine, hydration, and then a meal in the early part of the day, your body will start to anticipate all of those activities.
