Avoid Artificial UVB Exposure at Night

Avoid UVB light from artificial sources between about 10 p.m. and 4 a.m. because even small amounts can disrupt sleep, energy, mood, melatonin, and dopamine-related pathways. If you have depression or low mood, be especially cautious even in the late evening, roughly 8 p.m. to 4 a.m.

“It's only at night, basically between the hours of about 10 p.m. and 4 a.m., that even a tiny bit of UVB exposure from artificial sources can mess us up in terms of our sleep and our energy levels and so on.”
