As Bastian Groiss says, people see light as an enabler for vision. But light - sunlight in particular - is so much more. It triggers hormonal reactions, allows your immune system to recharge and gives the mitochondria the energy to repair your eyes. Of course healthy light during the day allows healthy darkness at night to do its thing. And stop wearing sunglasses! Bastian is of German origins with a rural upbringing. He is a former project manager, self taught wood worker and handyman, spiritual explorer, student of the Diamond Approach, ambassador for regenerative agriculture, circadian rhythms, natural light and reconnecting with nature.
