Boost Mitochondria with Sunlight & Infrared light | Glen Jeffery

Live Longer World

We’re only just waking up to the benefits of sunlight and red light for mitochondrial health, lowering blood glucose, and potentially treating Parkinson’s disease and cancer.

Dr. Glen Jeffery is at the leading edge of this research.

We discuss:

- Health benefits of sunlight and red light

- Harmful effects of blue light & LEDs

- In the 2nd half of the podcast, I ask him rapid fire practical questions that everyone wants to know about light, ranging from how much sunlight should one get to what time of day is best for infrared light exposure.
