A common sunscreen ingredient turns toxic in the sea – anemones suggest why
I never use sunscreen at the ocean, both because I just hate putting it on and because I always thought it was probably not the best thing to put that crap directly into the ecosystem.  Unless I&#x27;m spending a ton of time at the beach, which rarely happens, I feel like I can deal with an hour or so of that kind of sun exposure every now and then.<p>If one is spending a ton of time in the sun, then yeah, use sunscreen.  Since I&#x27;m indoors most of the time, I rarely find sunscreen that helpful.  Anecdotally, I think I became more sun tolerant after changing my diet.  In short, I highly limit eating processed foods and stick to meat and some plants that are low in natural defense chemicals.  Since that&#x27;s a low-inflammatory diet, maybe that explains it.  But I&#x27;m purely speculating.
