Modern film spikes your cortisol and leaves you worse off than before

You sit down to watch the latest trending series. Ten minutes in, you sense something is off: the camera never stops moving, shots last less than three seconds, your heart rate speeds up, and by the time the episode ends you're more drained than entertained. It's not your imagination: a growing chorus argues that today's film editing is designed to keep you in a state of chronic alert, and that this visual bombardment has direct consequences for your wellbeing.

Shot pacing as a stress mechanism

One of the theories gaining the most traction holds that the audiovisual industry has figured out that nervousness drives engagement. The more the camera moves and the faster the cuts come, the more cortisol — the stress hormone — we secrete. In a film or series from thirty or forty years ago, scenes unfolded at length, shots were stable, and viewers could breathe. Today, even in productions without breakneck action, the editing is jittery, almost convulsive. The result isn't excitement, it's anxiety.

Supporters of this hypothesis point out that the effect is cumulative: after hours of this kind of content, the nervous system doesn't relax but stays tense. And if the plot is tragic or violent on top of that, the combination can leave viewers worse off than before they turned on the screen.

Is this exclusive to modern cinema?

Some push back, noting that cinema has always dealt in tragedy. Think of Titanic, where the central couple meets a cruel fate. But there's a nuance: back then the dramatic weight lay in the story and the characters, not in sensory overstimulation. A sad film shot with long, unhurried takes lets you process the emotion; one shot with frantic editing imposes it rather than suggesting it. The difference isn't just stylistic, it's physiological.

The unsettling data point

While some argue that today's cinema is more addictive than ever, others point out that the same was said of 1970s cinema, or of any era. But the anecdotal evidence is overwhelming: people finish series marathons feeling empty, not satisfied. The debate isn't settled, but there's an uncomfortable consensus: modern audiovisual consumption, with its hyperkinetic editing and obsession with keeping you glued to the screen, is designed to exploit your biology, not to enrich your leisure time. And that, whether you want to admit it or not, is costing you more than you think.
