Summary

Researchers are testing whether an 8-week course of Joovv infrared light therapy can change hormone levels in healthy adults. The study measures testosterone in men and estrogen, progesterone, and thyroid-stimulating hormone in women, along with general wellness. Participants use the at-home device and complete questionnaires at the start and end of the study.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Joovv infrared light therapy device
What this could lead to
If it works, at-home red light therapy could offer a drug-free way to support hormone balance in healthy adults.
What could go wrong
This is a small, early pilot with no control group, so any hormone changes could be due to chance or lifestyle. Light therapy may also have no measurable effect on hormones at all.
