Sounds!

Results of a massive study of 272,229 European adults were published this week, “Metabolic Profiles of Nighttime Road Traffic Noise Exposure,” in Environmental Research, by researchers from Finland, Netherlands, UK, and the USA.

Annual average nighttime road traffic noise was linked to the individual residential addresses of all the subjects at the time of blood sampling, using national noise maps. We utilized high-throughput nuclear magnetic resonance metabolomics to profile 155 blood biomarkers (including lipids, lipoproteins, fatty acids, and other low-molecular-weight metabolites).”

And the result?

Nighttime road traffic noise (≥55 dB versus <45 dB) was associated with higher levels of 48 metabolites looked at. Noise (≥55 dB) was associated with elevated circulating concentrations of cholesterol-related biomarkers, including low-density lipoprotein (LDL) and intermediate-density lipoprotein (IDL), as well as unsaturated fatty acids and membrane biomarkers.”

The pattern held even after accounting for air pollution, body weight, smoking, sex, and education level, suggesting noise itself may be a factor rather than other variables associated with living near busy roads. And 55 dB is not very loud at all—the level of noise in a fairly active residential street!

Of course, no direct cause and effect was established between sounds and the metabolic markers, but researchers point to the body’s stress response as the most plausible explanation. Nighttime noise fragments sleep, even when people don’t fully wake up. Disrupted sleep activates stress pathways, releasing hormones like cortisol that, over time, interfere with how the body processes fats and regulates cholesterol. Chronic exposure likely compounds the effect: a little disruption night after night for years, quietly nudging lipid levels in the wrong direction.

We thought the biggest threats to our cholesterol came from the kitchen. Maybe, but also from our roads. And in our beds.

What made the pattern especially convincing was its consistency. Effects were virtually absent below 50 decibels. They began climbing between 50 and 55 decibels. At 55 and above, the cholesterol associations were statistically robust and replicated across all three countries with almost no variation between groups.

Get out those ear plugs, folks!

But there is one sound that should lower all those bad things in the blood because … it is the “voice of Yahweh”!

The voice of Yahweh is upon the waters;
the God of glory thunders—Yahweh upon great waters.
The voice of Yahweh in power,
the voice of Yahweh in majesty.
The voice of Yahweh breaks the cedars; Yahweh thoroughly breaks the cedars of Lebanon.
And He makes Lebanon skip like a calf, and Sirion like a young wild ox.
The voice of Yahweh splits flames of fire.
The voice of Yahweh quakes the wilderness; Yahweh quakes the wilderness of Kadesh.
The voice of Yahweh quakes the large trees and strips the forests [bare].
Psalm 29:3–9

This section is striking for its seven-fold repetition of “the voice of Yahweh” (“voice” = “sound” in Hebrew). Of note, Baal is also enumerated seven times in a Ugaritic list (ca. 2000 BC). That Canaanite theology is in the background is not surprising; the geographical references—Lebanon, Sirion (i.e., Hermon), and Kadesh—indicate northern Canaan as the scene of all this divine activity. But enemies of any kind are no match for God. Just the “voice of Yahweh” throws these strongholds into disarray!

And that, folks, should lower our cholesterol, our BP, our stress, and our anxiety.

For it continues:

And Yahweh, King, sits [enthroned] forever.
Yahweh, strength to His people He gives;
Yahweh, He blesses His people with peace.
Psalm 29:10–11

So …

Ascribe to Yahweh the glory of His name;
worship Yahweh in [His] holy majesty.
Psalm 29:2
