Sun by day. Darkness at night.
But researchers are also studying near-infrared light as a targeted tool for the brain. š§ āØ
In todayās episode with neuroscientist Ramona von Leden, PhD (), the Scientific Advisor at we get into photobiomodulation (PBM) and why itās being explored for sleep, recovery, and brain performance.
Wild highlights š
⢠A small randomized sham-controlled insomnia trial found transcranial PBM improved sleep quality scores and daytime sleepiness in just a week.
⢠Another sham-controlled trial found a red + near-infrared neck device before bed improved perceived sleep and relaxation, even though actigraphy didnāt shift.
⢠Mechanisms being studied include mitochondrial signaling and nitric oxide effects, plus a ābrain cleanupā angle (glymphatic) in animal research.
