You’re probably stressed.

Of course you are: anxious, jittery, nervous, worried about work obligations or family chores that are late getting done.

How do I know?

Because you’re American, and stress is part of our national psyche.

Trust me, I’ve lived and worked in other parts of the world, and people seem to sail through days and sleep soundly at night — not always, but certainly more than we Yanks ever manage.

Have you read Liz Gilbert’s billion-selling book “Eat Pray Love,” or seen the watered-down movie version with Julia Roberts?

Gilbert was a depressed, divorced wreck who decided to spend a year abroad — in Italy (to understand enjoyment and relaxation), in an Indian ashram (to learn peaceful prayer) and then Bali (to find balance in her life).

WHILE SHE was in Rome, Liz encountered a new friend with the improbable (but real) name of Luca Spaghetti.

Liz carried on about how Americans work like crazy, then ultimately take time off but aren’t even able to relax on a holiday. She asked Luca if Italians have a similar problem, and he burst out laughing.

“Oh, no,” he said. “We are masters of ‘il bel far niente.’ ”

That Italian phrase means “...the beauty of doing nothing.”

True relaxation, in other words.

Meanwhile, Americans try yoga, meditation (of a sort), working out at the gym and all sorts of other things to clear our stress-clogged minds, and it rarely works — probably because we’re treating it like one more task to be completed.

BUT I have good news for everyone buried in anxiety — and you, too, in fact.

First, some numbers: Anxiety disorders affect 40 million adults between the ages of 18 and 54, and the number is going up dramatically in the United States.

You’ve probably heard that music can help you relax, that it assists in shedding all that pent-up stress.

Well, neuroscientists in Great Britain have discovered that one song in particular reduced anxiety in trials by an incredible 65 percent.

Dr. David Lewis-Hodgson of Mindlab International tested participants’ anxiety levels as they listened to different songs while completing a series of puzzles, while researchers measured brain activity and physiological states — including heart rate, blood pressure and breathing.

What they discovered was that some songs caused stunning drops in anxiety and nervousness as the subjects grappled with the puzzles.

In fact, the song “Weightless” by Marconi Union produced a 65 percent drop in anxiety across the board.

THIS SOUNDS like bunk, I know, so I listened to “Weightless” a few times, wearing a headset to block out the world.

And yes, it’s almost like hypnosis.

Now obviously, different songs are likely to work with different people.

Common sense suggests you avoid “Danger Zone” from the movie “Top Gun,” or any of Bruce Springsteen’s awesome tunes.

“Thunder Road” might help you getting ready for work, but maybe not for relaxation.

C’mon, go ahead and try “Weightless.”

I put it on Tuesday night, and slept until this morning.
