5 Causes of Circadian Disruption You May Not Know

Feeling tired but wired…sleepless nights…trouble waking up?

Any of these can be signs of circadian disruption—meaning your external daily rhythms are out of sync with your internal body clock.

We can correct the problem, but first we need to know the cause, right?

Most people know that working nights will mess with your body clock, but here are 5 other causes of circadian disruption you may not know:

1️⃣ Sleeping In On Weekends

Sorry to be the bearer of bad news, but if you wake to an alarm 5 days a week and sleep until noon on the other 2, your body feels like you’re constantly traveling between time zones. It’s called social jet lag and can do more harm than good. 

2️⃣ Being a Night Owl

Lots of people think being a night owl is just a personality trait like anything else. Unfortunately, studies show that night owls are more likely to experience circadian disruption and are at a higher risk for some conditions, like diabetes. 

3️⃣ Poor Diet

Both the types of food you choose and the timing of eating can alter the patterns of gut microbiota, which then influence circadian clocks in the gut. Digestion and blood sugar regulation follow a daily rhythm, so your eating patterns should too. 

4️⃣ Alcohol Consumption

Chronic alcohol consumption alters the timing of the liver clock and causes a mismatch with your central circadian rhythm. This can happen with even small amounts of alcohol when combined with other variables, like working at night. 

5️⃣ Working Indoors

The most powerful external influence on our body clocks is the 24-hour light-dark cycle. If you work in artificial light, your body misses out on the benefits of full-spectrum natural light. Solutions could include taking outdoor breaks or investing in a light-therapy lamp. 

The bottom line? If you struggle with your energy level or sleep, there’s a chance circadian disruption might be at play.

5 Signs Your Circadian Rhythm Might Be Off

Daily rhythms keep your body ticking like a clock. 

It’s true for morning glories, crickets, birds, dogs, and yes—humans too. 

Here’s a non-exhaustive list of body processes that follow a 24-hour clock:

✔️ Hormones

✔️ Blood Pressure

✔️ Blood Sugar

✔️ Immune Function

✔️ Detoxification

✔️ Digestion

That’s right—nearly every body process has a daily cycle. 

⏰ It’s called the circadian rhythm ⏰ 

We have a master circadian clock in a specialized area of the brain called the suprachiasmatic nucleus (SCN) plus self-regulating clocks in the gut, liver, and other internal organs. 

BUT…do you know what happens when we eat, exercise, sleep, or stare at our phones at times that are out of sync with our internal clock?

It’s not good. 

When our rhythm gets out of whack, it’s called Circadian Disruption. It can look like:

✖️ Unable to fall asleep

✖️ Difficulty staying asleep

✖️ Waking up groggy

✖️ Crashing mid-day

✖️ Feeling tired but wired

Not only that, but circadian disruption can upset your mood, metabolism, hormones, and digestion too.

[New Study] Night Owls at Higher Risk of Insulin Resistance

🤔 Would you consider yourself a night owl or an early bird? 

Turns out it might affect your metabolism.  

A new study shows that people with metabolic syndrome who tend to stay up late and sleep late (any night owls out there?) have a higher risk of developing type 2 diabetes. 

Yikes. 

The difference relates to a topic I’ve recently shared about—

⚠️ Insulin Resistance ⚠️


Here’s how the study went:

👫 51 participants with metabolic syndrome were monitored for a week for their activity patterns over the day. 

🥗 They all ate the same diet, controlled for nutrition and calories. 

🐥 Results showed that early birds burned more fat for energy (both while exercising and at rest) and had better insulin sensitivity. 

🦉 Night owls’ bodies favored carbohydrates as a fuel source and were more insulin resistant. 

This study involved people who already had metabolic syndrome, so we don’t know if it also applies to healthy people. 

Still. Knowing this link between staying up late and insulin resistance is one thing. But what can we do about it? 

Do you believe that it’s possible for night owls to become early birds? 🤷‍♀️
