#1794 Circadian Rhythms

How’s Yours?

This is +1 #1794.

Way back in the late 1490s 🤓, we spent some time with Dr. Satchin Panda and wisdom from his brilliant book, The Circadian Code.

(Check out the series of +1s on Move Your Body!, 6:00 P.M. to Midnight, Circadian Chickens, and WHEN to Eat (vs. What))

As I reflected on our recent +1 about me Target swiping my practice of getting some early morning sun, I realized we should revisit circadian rhythms.


Let’s do that.

First, context setting.

Satchin Panda is one of THE world’s leading researchers on the SCIENCE of circadian rhythms.

In The Circadian Code, Dr. Panda tells us: “You may have heard of circadian rhythms before; a 2017 Nobel Prize recognized this field of research for its impact on human health. But if you haven’t heard of circadian rhythms, don’t worry; the concept is very simple. The word circadian comes from the Latin circa, meaning ‘around’ (or ‘approximately’), and diem, meaning ‘day.’”

He continues by saying: “Circadian rhythms are real biological processes that every plant, animal, and human exhibit over the course of a day. These rhythms are actually interconnected among species and are governed by internal circadian or biological clocks. ...almost each and every one of our cells contains one of these clocks, and each is programmed to turn on or off thousands of genes at different times of the day or night.”

And: “These genes influence every aspect of our health. For instance, when we are healthy, we can have a good night’s sleep. In the morning, we wake up feeling fresh and energetic and ready to get to work. Our gut function is perfectly normal. We have a healthy hunger and a clear mind. In the afternoon, we have the energy to exercise. At night, we are tired enough to go to sleep without much effort. Yet when these daily rhythms are disturbed for as little as a day or two, our clocks cannot send out the right messages to these genes and our body and mind will not function as well as we need. If this disruption continues for a few days, weeks, or months, we may succumb to all types of infections and diseases, ranging from insomnia to attention deficit hyperactivity disorder (ADHD), depression, anxiety, migraine, diabetes, obesity, cardiovascular disease, dementia, and even cancer.”

And, finally: “Luckily, it’s easy to get back in sync. We can optimize our clocks in just a few weeks. By restoring our circadian rhythms, we can even reverse some of the diseases or accelerate cures, returning us to better health.”

Let’s start at the top with a super-quick recap…

The word circadian comes from two little Latin words: circa and diem.

As you probably already know, it means “approximately a day.”

What you may NOT have known and/or paid much attention to is the fact that…

EVERY SINGLE (!!!) plant, animal and human being (that would include YOU!), has a built-in natural rhythm that has been finely tuned over the last (tens and hundreds of!) millions of years.

Violating that natural rhythm is NOT a wise idea.

I repeat this warning from Dr. Panda: “The longer your circadian rhythm is out of sync, the greater the risk of developing a serious disease.”

Good news...

It’s relatively easy to get back in sync.

Some Heroic Targets I personally hit to stay in sync?


“I Love Starting My Day with Early AM Sunlight” 🎯

Note: This is one of THE most powerful ways to reset our ol’ circadian rhythms/make sure we’re aligned which is why I do it every day!

“I Have Fun Getting to Bed by 9:00 p.m.” 🎯

That’s currently about an hour after the sun sets in late spring in Texas. Aligning with the sun is a wise idea…

“I Love Having My Last Meal 4 Hours Before Bed.” 🎯

This is both a great way to give my glymph time to work AND a great way to honor Dr. Panda’s recommendations on creating an appropriate fasting window which leads to…

“I Love TRE [Time Restricted Eating] (10 hours = 14 hours = 6:30-4:30 = Done)” 🎯

A 10 hour eating window equals 14 hours of time restricted eating (fasting window)—6:30am to 4:30pm roughly and I’m done.

One of THE Big Ideas from Dr. Panda’s book is the fact that WHEN we eat and restricting that to no more than a 10-hour eating window to give ourselves at least 14 hours of NOT eating is one of THE fastest ways to boost our well-being while optimizing our circadian rhythms.
