I’m no doctor... but my guess would be that breathing in particulate mater into your lungs might be the issue... not that chemicles would leach out into your planter. It’s probably to get you to wear a dust mask.
And as I have posted before. If you get tree trimmers chips and mulch and wood chips dropped on your property then buy and wear a good mask from Amazon to keep mold out of your lungs.

I agree after one day working with fresh moldy tree mulch showing friable white powdery mold I began to feel the effects, cough and tightness in chest. After the mulch had aged a few months and been wetted it required no more use of the mask.In USA you need a mask government rated P-100 for dust/mold particulates. Since this sort of work is strenuous and you will be breathing heavy suggest a full nose/mouth mask not just the paper type masks. Use only P-100 class particle filters not vapor filters.https://www.homedepot.com/p/3M-Medium-Mold-and-Lead-Paint-Removal-Respirator-Mask-6297PA1-A/202078789The 3M™ Particulate Filter 2091 P-100 filters are 99.97% effective for the particles we are speaking of.
It does rot eventually but it takes a lot longer than 2 years. Ive got all my boxes made from this same stuff, going on 4 years now, they look like they will last another 4 years.
Your in an arid area lacking rain. Im in a humid area with Redwood forest, so 2 years here and Doug fir 2 X's are swiss cheese or mulch.You can buy scrap redwood that will last much longer for the 4 X's but it's usually too exspensive to do the sides in redwood. It think raising garden bed's above the earth is usually a losing battle against nature. Better to double dig, and amend French Intensive style, 7 x's the produce in the same area.

They work great. When your ground is too hard to dig its easier to build a bed.I pay 30$ for 3 8ftx1ft pieces. Cut one half then screw the ends together. Thats its, 12 deck screws and 3 pieces of pine and get many years out of them. Its a no brainer.
I got a jackhammer and some really nice granite slabs that need loosening up. Stop by anytime and show how its done.
