[ABAD] Part 1. Why Does a Day Begin at Sunset? A Biblical Insight Meets Modern Sleep Science

“And There Was Evening”: Why Your Day Should Start at Night

“And there was evening, and there was morning—the first day.”
Genesis 1:5

We usually think a day starts when we open our eyes in the morning.

But the Bible paints a different picture. In Genesis, each new day begins not with sunrise, but with sunset.

At first glance, this might seem like just an ancient way of marking time. But modern science suggests there’s something deeper going on here. In fact, the idea that your day begins at night may be one of the most biologically accurate and mentally healthy perspectives you can adopt.

Sleep as the Real Beginning

Your body runs on a 24-hour internal clock called the circadian rhythm. As the sun goes down, your brain naturally starts producing melatonin, a hormone that prepares you for sleep.

In other words:
Your day doesn’t begin when you wake up.
It begins when you start winding down.

Think of it like building a house: sleep is the foundation. Without a strong base, no matter how beautiful the structure, it won’t stand. Likewise, without quality rest, your productivity, mood, focus, and immune function are already compromised before the day even starts.

Here’s a striking fact:

Just one night of poor sleep can reduce cognitive performance by up to 40%—more than the effect of being legally drunk.

We don’t wait to pour the concrete after the house is up. So why do we treat sleep as an afterthought?

Science Says: Better Nights = Better Days

This isn’t just philosophy. It’s backed by science.

According to the National Sleep Foundation, people who follow a consistent bedtime routine and begin winding down 60–90 minutes before sleep report:

  • More restful sleep
  • Improved mood the next day
  • Greater focus and productivity at work or school

A 2021 study from Harvard Medical School found that people who practiced intentional pre-sleep habits, like turning off screens early, dimming lights, and engaging in relaxing activities, showed up to 30% better cognitive performance the next morning compared to those with irregular or screen-heavy nights.

Even more striking:

The performance difference between a well-rested brain and a sleep-deprived one can exceed the cognitive decline caused by alcohol.

In other words, starting your day tired is like starting your workday drunk. That’s how foundational sleep really is.

And sleep quality doesn’t start when your head hits the pillow.
It starts with how you treat the hours before bed.

By intentionally winding down at night, rather than crashing into sleep, you’re not ending your day.

You’re building tomorrow’s success.

Ancient Time vs. Industrial Time

In today’s world, time is built around productivity.
Wake up → Work → Rest.

But in ancient Jewish tradition, a new day began at sunset:
Rest → Rise → Work.

This wasn’t just cultural. It was human.

We are designed to recharge before we perform.

Imagine redesigning your day like this:

  • Evening: Wind down and unplug
  • Night: Deep, restorative sleep
  • Morning: Wake with clarity
  • Daytime: Create, work, produce

Seen this way, tomorrow begins tonight, not just spiritually, but biologically.

Try This: A 3-Day Sleep Reset

Here’s a micro-action challenge:

🕰️ Set a wind-down alarm 90 minutes before bed
💡 Dim the lights, reduce screen time, and do one calming activity
📝 Write down one intention for tomorrow—then forget about it until morning

Try this for just 3 nights. You might be surprised how your mornings begin to transform—not because you did more, but because you rested better.


Final Thought

The ancient words, “And there was evening, and there was morning…”, weren’t just poetic.

They hold a truth we’re rediscovering today:

Your day doesn’t start when you wake up. It begins when you lie down.

Start your day with rest because recovery isn’t the reward.
It’s the beginning.
