Here is why sunlight feels like an instant mood shift. Gerardo Gutierrez of Mitolux explains how UVB, near-infrared light, & full-spectrum exposure support vitamin D, hormones, circadian rhythm, & long-term energy, plus how to bioharmonize your light routine even on busy or cloudy days. Meet our guest Gerardo “Guti” Gutierrez is the founder & CEO of MitoLux, inspired by his own recovery from pre-diabetes, low testosterone & depression through sunlight, movement & targeted light protocols. After transforming his health in just four months, he launched MitoLux to help others do the same. Guti now teaches how UVA, UVB & red light influence biology, circadian rhythms & overall well-being.
