Does that mean a bulb like one of these would be useful for those of us stuck in foggy/cloudy climes (like San Francisco): https://www.amazon.com/s?k=uvb+reptile+light

#134This isn't big news at all. Melanocyte-stimulating hormones have been known to stimulate sexual behavior since forever. Melanocortin receptors directly modulate sexual behavior. Melanocyte-stimulating hormone production is boosted by from inflammatory effects of UV damage. This has been known forever, too.
Anyone who has taken Melanotan-2 or PT-141 could tell you this ;^)

#135Or maybe tan people just look more attractive and get more attention
Or just people that work in field don't watch so much porno.

#137Bremelanotide, a medication used to treat low sexual desire in women, has skin hyperpigmentation as a side effect. Could there be a connection? https://en.wikipedia.org/wiki/Bremelanotide
My bodybuilder friend used to inject Melanotan II (?) and would get super tan after just a couple days of summer. He'd also get wild random erections while on it. It's an anecdote, but the post title instantly made me think of that.
There’s a few decades of small studies confirming this: from 2000:

> boosted by from inflammatory effects of UV damage That wording supports a notion that the boosting is to encourage the most essential activity of a species—reproduction—in the face of potential harms that may shorten the opportunity for that activity (cancer-induced final exit). That said, I’m aware of counterarguments to the simplistic takes on “sun bad” messaging and think they have merit. Not trying to open a de…
That seems a bit simplistic of an interpretation when there are no similar effect for dehydration, hunger, loss of a limb, or other potential harms.
Many animals are seasonal. And extra sun exposure might indicate a good time to mate (spring/summer)

I would normally be a bit skeptical of anything published by CSPI.
Why? Do you care to elaborate, or do you prefer to just cast vague aspersions?

Interesting nonetheless, thanks for sharing! Slightly related: I've decided to stop using suncreen altogether for day-to-day sun exposure. My mood and overall sense of happiness increased significantly – in fact, it seemed to have helped more than my antidepressants ever did. (My libido did not increase but my antidepressants are pretty much libido killers.)
I’ve been seeing more and more evidence that we may not be getting enough UV exposure in general in the US. Vitamin D production is big, but what fewer people know about is nitric oxide which is also sythesized from UV exposure. It is a muscle relaxer that lowers blood pressure. It would undoubtedly have a positive effect on your mood.
