Cognitive decline and brain fog are issues that affect millions of people, whether due to aging, neurodegenerative conditions, or lifestyle factors such as chronic stress, poor sleep, and nutritional deficiencies. Near-infrared light therapy, typically delivered in the 810 - 850 nm wavelength range, has demonstrated remarkable potential in supporting cognitive function.

This form of light penetrates deeply enough to reach the brain through the skull, where it
stimulates mitochondrial activity in neurons, enhancing ATP production and thus improving cellular energy availability. Enhanced mitochondrial function supports processes such as neuroplasticity, synaptic activity, and cellular repair mechanisms
(NIH). A growing body of research in the field of photobiomodulation indicates that near-infrared light improves cerebral blood flow, thereby enhancing oxygen and nutrient delivery to the brain. This not only supports immediate improvements in alertness and mental clarity but may also protect against long-term cognitive decline. Studies have shown that consistent near-infrared therapy can improve memory, attention, and executive function in older adults, as well as provide neuroprotective effects in
models of Alzheimer’s disease and traumatic brain injury (PubMed).

An especially interesting finding is the effect of specific pulsing frequencies, such as 40 Hz. This frequency has been studied for its ability to induce gamma brain wave entrainment, which is associated with learning, memory, and overall higher-order cognitive processes. In animal models, 40 Hz stimulation has even been linked to reductions in amyloid-beta plaques, which are hallmarks of Alzheimer’s pathology (NIH). While human studies are still emerging, the preliminary data is very promising. Beyond disease-specific applications, many people use near-infrared therapy to counteract everyday brain fog.

Whether due to long work hours, digital screen exposure, or disrupted sleep cycles, the
modern lifestyle often leaves individuals mentally drained. Near-infrared light sessions can serve as a natural cognitive enhancer, offering a safe, side-effect-free alternative to stimulants like caffeine or prescription drugs. Users often report increased focus, clearer thinking, and greater mental stamina after consistent use. Overall, the combination of enhanced mitochondrial energy, improved blood flow, and potential neurological entrainment makes near-infrared light an exciting frontier in cognitive health. With devices like the Kivo Elite Panels or Kivo Pro Panels offering adjustable pulse frequencies and targeted near-infrared delivery, this therapy is becoming increasingly practical for at-home use, empowering individuals to take charge of their brain health proactively.
