Morning sunlight exposure sets up the circadian rhythm and influences melatonin production.

“Morning sunlight (or if it helps you to think about it as daylight so you still get it on overcast days) is the circadian rhythm setter (and so much more).”

“Sunlight in the am is still needed of course.”

“And as many of you know, sunlight and the viewing of light is also very important for setting circadian rhythm.”

“And I should mention within the on and on and on, it's also going to suppress any melatonin, a hormone that makes you sleepy that happens to be swimming around in your bloodstream at the time you wake up.”

“sunlight is important for us it's important for setting our circadian rhythms”

“let's get some vitamin D, straighten your eyes first thing in the morning, set circadian rhythm.”

“you need to watch the sunrise so you need to see sun within the first hours of your day”

“I'll get the Sun so I can reset my circadium rhythms”

“Now, this is an important moment to also point out that your nighttime routine almost starts in the morning because you're getting morning sunlight in the morning and that sets up your circadian rhythm. Your production of melatonin is something that's engaged with your circadian clock for the whole day.”
