Artery calcification more common in night owls, shows study
Medical Xpress / Sahlgrenska Academy / Sleep Medicine ^ | Dec. 21, 2023 | Mio Kobayashi Frisk et al

Artery calcification is almost twice as common in night owls compared to early birds, according to a study. Circadian rhythm appears to be particularly important for the heart and blood vessels during the early stages of the disease.

Artery calcification, or atherosclerosis as it is also known, involves fatty deposits accumulating on the inside of the arteries, making it harder for blood to pass through.

The study, involved 771 men and women aged between 50 and 64, all of whom are part of the larger population study SCAPIS.

The degree of artery calcification in the heart's coronary arteries was examined using computer tomography. Participants themselves indicated their so-called chronotype on a five-point scale: extreme morning type, morning type to some extent, neither morning nor evening type, evening type to some extent, or extreme evening type.

Of the 771 participants, 144 identified as extreme morning types, and 128 as extreme evening types. Among the group who were most alert in the morning, 22.2% had pronounced artery calcification—the lowest proportion of all five chronotypes. The extreme evening type group had the highest incidence of severe coronary artery calcification, at 40.6%.

First author of the study is Mio Kobayashi Frisk. "Our results indicate that the extreme evening chronotype may be linked not only to poorer cardiovascular health in general, but also more specifically to coronary artery calcification and to the process that leads to artery calcification," Frisk says.

Each chronotype can be said to have an average time when half of the night's sleep has passed. In a previous study on the same population, though not necessarily the same individuals, this time occurred at 02:55 AM for the extreme morning type group and at 04:25 AM for the extreme evening type group. The remaining chronotype groups' mid-sleep times were between.

22.2% of morning people had severe coronary artery calcification, while 40.6% of night owls had that.

I am a night owl, but this becomes another incentive to endeavor to change that.

It may be mere correlation, and not causative.

This seems strange to me. 90 minutes difference in sleep midpoint times doesn't seem like a lot to separate the two extreme groups.

When I was young (20s), I'd say that I was an extreme night owl, preferring to stay up until 3 or 4 am and then to sleep until the very late morning. By my mid-fifties, I had shifted to an extreme morning person schedule, seldom sleeping later than 4:00 am. Even now, 3 1/2 years after retiring at 65, I'm usually wide awake by 5 every morning.

I’m wondering if this is not a correlative and not a causitive function.

Why?

Because morning people tend to get more sunlight than night owls

Too few people know to get enough vitamin d3 K2 when they’re not in the sun.

there are other risk factors for night owls that fewer morning people will experience.

For example—which group do you think would be more sendentary—and therefor more prone to carry weight and suffer other maladies that go with a sedentary life? the morning people or the night owls.

It doesn’t sound like they took diet into consideration, unless it can be deduced based on blood lipids and weight, which they did take into consideration.

Good post yours, as usual. Over the last year I’ve tried to change my sleeping habits, and with some success. It took a mild prescription from my doctor. On the other hand, my pet owl is stubborn, and refuses to change.

Sleep is overrated, waste of time. I try to do as little of it as possible.

Tablespoon of organic extra virgin olive oil when you wake up and before you go to bed everyday.

Also, serrapeptase everyday.

Look up the benefits for both and you’ll be impressed. Japanese have been using it forever.

Fyi, reduced my blood pressure from 148/98 to 125/80 in 4 months

First, Koncentrated K (supplement).
Sold on Amazon and they have a website with great info if you’re interested.

And then… there is the drink that removes plaque.
I’ve done it twice and got a clean report.
Hadn’t always been that way.

So definitely things you can do.

has anyone has some success with niacin for this? I get the expected flush but it also shows up in my knees as they turn brighter red than the rest of my body.

Aspirin does get rid of the itching but not sure I should get rid of it.

If you have tinnitus you should try niacin to see if opening up the vessels changes the ringing.

What if a person is a night owl / early bird combo?

:-)

Merry Christmas!

“Sleep is overrated, waste of time.”

That could be why I don’t get a lot of sleep. When I’m trying to doze off the wheels are turning thinking about what interesting things I could be doing.

No matter what, I pretty much always get up at 6am.

I don’t know. My dad was a nightowl and never had any heart issues. Dad professionally restored high end cars, he would wake up thinking about a difficult job and get out of bed and go do it. He did that for years and lived to be almost 90.
