Sun and Human Biology
The discussion highlights how modern lifestyles, which confine us indoors for the majority of our waking hours, disrupt our natural biological rhythms that evolved in harmony with sunlight. It emphasizes the importance of UV radiation, particularly UVB, and its critical role in human physiology, while also touching on the historical implications of migration and skin pigmentation in relation to sun exposure. Understanding these dynamics is essential for reconnecting with our biological roots.In this clip

Is it correct that SAD lamps emit blue and visible light to help set circadian clocks and improve mood, while UV light from sunlight has benefits for Vitamin D production and infrared light is beneficial for skin and mitochondrial health?
So SAD lamps emit blue and visible light, which helps set circadian clocks and improve mood. On the other hand, UV light from sunlight has benefits in terms of Vitamin D production and infrared light for skin and mitochondrial health. Is that right?
