The Optics of the Body: How Sunlight Massively Boosts Total Body Antioxidants

We hunted and gathered food found exclusively in the outdoor environment. As such, we evolved to be outdoors in the Sun for much of the day. Therefore, the advice given by dermatologists to avoid the Sun runs contrary to the evolutionary evidence. New information about the human body's optical qualities is reshaping our stance against sunshine. Near-infrared (NIR) light penetrates deeply into our body, unlike UV and visible light. Evolutionarily, the human body has developed optical mechanisms to gather and localize NIR photons in the most sensitive areas of the human body: blood vessels, retina, brain, skin, and even the womb. Research has demonstrated that NIR stimulates the production of antioxidants deep within our cells at the sub-cellular level. We use the reservoir of antioxidants to enhance the body's ability to contend with changing conditions throughout the day. I will cover some amazing things light does for our health and how you can maximize your light exposure.
