What was claimed

A new study found sunlight PASSES THROUGH the human body, RAPIDLY boosting mitochondrial function and improving vision

Our verdict

Needs Caution

A 2025 Scientific Reports study found that longer wavelengths in sunlight, particularly around 850 nm, can penetrate the human body, with only about 0.004% of that light passing through the thorax. Saying "sunlight passes through the human body" without specifying the limited near‑infrared component and tiny fraction that transmits is an overgeneralization that misrepresents the phenomenon. The study shows that exposure to these longer wavelengths improves mitochondrial function and ATP production, but the word 'RAPIDLY' is not supported by the research. The improvements were measured 24 hours after exposure, not immediately. The study does not characterize the boost as 'rapid.'.

Detailed Analysis

Parts of the claim reflect a real 2025 study showing that longer wavelength, near‑infrared light can penetrate the body and is associated with improved mitochondrial function and vision. However, the phrasing "sunlight PASSES THROUGH the human body" and "RAPIDLY boosting" is overstated and misleading, because only a tiny fraction of specific wavelengths pass through and the study used controlled 850 nm LED exposure, not general sunlight. The response mixes accurate core ideas with exaggerated language that could mislead a lay reader about the magnitude, mechanism, and conditions of the effect.

A new study found sunlight RAPIDLY boosts mitochondrial function in the human body

Misleading85%
The 2025 study and related reviews report that longer‑wavelength red/near‑infrared light improves mitochondrial function and ATP production, likely via interaction with mitochondrial proteins such as Complex IV.[1] [2] [4] [8] However, the study used controlled 850 nm LED exposure for 15 minutes, and effects were measured 24 hours later, so describing this as sunlight "rapidly" boosting mitochondrial function, without conditions or time course, is an exaggeration and could imply a faster, more general effect than shown.[1] [2] [4]

A new study found sunlight improves vision by passing through the human body

Verified90%
The 2025 Scientific Reports paper "Longer Wavelengths in Sunlight Pass Through the Human Body and Have a Systemic Impact Which Improves Vision" reported that 850 nm light delivered to the back improved visual performance 24 hours later, even when the eyes were shielded.[2] [4] [8] This supports that longer‑wavelength light analogous to sunlight can pass through the body and is associated with systemic improvements in vision, although the study used LED light rather than direct sun exposure.[2] [4] [8]

What other AI think

The statement accurately reflects the findings of a legitimate peer-reviewed study published in Scientific Reports (July 2025). The study does demonstrate that longer infrared wavelengths penetrate the human body and improve mitochondrial function and vision. The phrasing is consistent with how the research is described in official sources.

Why this verdict

Claims checked

RAPIDLY boosting mitochondrial function

Misleading85%
The study shows that exposure to these longer wavelengths improves mitochondrial function and ATP production, but the word 'RAPIDLY' is not supported by the research. The improvements were measured 24 hours after exposure, not immediately. The study does not characterize the boost as 'rapid.'

This claim may mislead readers without added context.

Verified95%
The study shows that infrared wavelengths from sunlight can be measured after they pass through the human thorax. This is a peer-reviewed finding published in Scientific Reports.

improving vision

Verified95%
These exposures were associated with significantly improved visual function when measured 24 h later even in subjects in which light was blocked from the eyes. The study measured improvements in color contrast sensitivity.
The statement mixes false physical claims with unsupported health conclusions. There is no evidence that sunlight "passes through" the body in the sense implied, and the health effects described are not supported as stated.

Claims checked

Sunlight PASSES THROUGH the human body

Incorrect90%
Visible and near-infrared light penetrate only a few millimeters to centimeters of tissue and do not pass straight through the whole body as implied.

This claim may mislead readers without added context.

This sunlight RAPIDLY boosts mitochondrial function

Misleading75%
Certain wavelengths (red/near‑infrared) can affect mitochondrial enzymes in superficial tissues (photobiomodulation), but the claim that ambient sunlight passing through the body rapidly boosts systemic mitochondrial function is unsupported and overgeneralizes controlled findings.

This claim may mislead readers without added context.

This effect improves vision

Some targeted light therapy to the eye has been studied for specific vision conditions, but there is no credible evidence that sunlight passing through the body improves vision as the claim states.
