Near-infrared light boosts yeast growth in a deep-sea lab study
In a laboratory study of deep-sea yeast, near-infrared light at 880 nm increased growth, and blocking a mitochondrial enzyme reduced that effect.

What the research shows
The laboratory study exposed deep-sea yeast cells to near-infrared light at 880 nm, and this exposure increased their growth. When mitochondrial cytochrome c oxidase, an enzyme linked to energy production, was blocked, the effect of the light decreased.
This is early work done only on yeast cells, not on people. It helps explain how light may influence cellular energy metabolism, but it does not show effects on human health. Laboratory results usually need testing in animals and then in people before any practical conclusion.
What it means
The finding suggests that light may affect cell energy through the mitochondria, in a simple organism. It is still unknown whether the same happens in other organisms, including humans, or whether it would matter for health.
How to read it with care
A laboratory result in yeast does not replace a medical consultation. Anyone considering changes to diet, supplements or treatment should talk to a doctor or another qualified health professional.
