What does Huberman say about red light therapy lamps?

Andrew Huberman discusses the potential benefits of red light therapy, highlighting its use in several areas including acne reduction, wound healing, and possibly offsetting age-related vision loss. He notes that red light therapy involves the use of red or near-infrared light panels that can penetrate tissues, potentially enhancing mitochondrial function 1 2.

Huberman mentions that early exposure to red light, ideally within the first three hours of waking, can be beneficial. He uses red light therapy as part of his routine, particularly for addressing biological changes, and suggests ensuring that any red light source used has the correct wavelengths, typically between 650 to 800 nm 3 4.

He also points out that red light can help reduce evening cortisol levels, promoting better sleep by using dimmable red lights 5 2. While red light has some unique applications, it does not provide all the benefits of natural sunlight, particularly for increasing cortisol and dopamine levels necessary for waking up the system 6.
