For most of us, the day starts the same way: eyes open, hand reaches for the phone before the feet ever touch the floor. We hand over the first waking minute of the day to a screen full of other people's updates.
Your body was hoping for something else.
A clock that runs on light, not alarms
Tucked inside the brain is a small cluster of cells called the suprachiasmatic nucleus, and its entire job is to read the light coming in through your eyes and use it to set every other rhythm in your body: body temperature, digestion, hormone release, and how well you'll sleep that same night. It isn't reading a clock. It's reading light.
Cortisol is the hormone that gives you the natural lift to wake up and get going. In a laboratory study published in the Journal of Clinical Endocrinology & Metabolism, volunteers who moved from dim light into bright light in the morning showed an immediate rise in cortisol.
More recent research points the same way. A 2023 study in Clocks & Sleep followed 27 young adults and found that one hour of bright light in the morning moved the body's clock about eleven minutes earlier, helping to offset the delay that builds up when morning light is missed. In plain terms: light in the morning helps set you.
The light that steadies your mood, too
There's a third finding that deserves more attention than it usually gets. A study published in The Lancet found that the brain's serotonin turnover was linked to how much sunlight was available that day: brighter days went with more serotonin activity. It is an association, not proof of cause, but it matters beyond mood alone. Serotonin is also the starting material your body uses to make melatonin later that night, the hormone that helps you sleep.
Put simply: tonight's rest starts getting shaped in tomorrow morning's first minutes.
Your body was made to wake with the sun, not with a notification.
Stewardship, not another rule to follow
It's worth pausing here, because it would be easy to read all of this and turn it into one more thing to optimize, one more box to check on an already long list of what you "should" be doing for your health. That's not the point.
Your body isn't a project to manage. It's something to care for, and real care starts by noticing how something was designed to work, rather than forcing a rhythm onto it that was never its own. Your body was made to wake with the sun, not with a notification. Honoring that isn't a wellness trend. It's simply paying attention to what we already knew, long before the research caught up to confirm it.
Scripture gives the morning a prayer:
“Let the morning bring me word of your unfailing love, for I have put my trust in you. Show me the way I should go, for to you I entrust my life.”Psalm 143:8, NIV
Before you reach for your phone tomorrow morning, reach for the light instead. Your body, and tomorrow night's sleep, may feel the difference.
