Wait, does every woman who owns an Apple Watch also have a big diamond ring, wood floors and beige carpet?
Lol! And don't forget the manicures! I just about died of envy when I saw 3under2's nails. I'm doing landscaping and garden maintenance for my own property and now two others. I won't be able to have decent fingernails again until November.
To the OP, speaking from long experience from my landscaping work, I can say sweat and plastic against your wrist aren't a good mix. I'm not sure how much contact there is between the case bits and your skin but it's likely the case giving you some problems and putting too much space between you and the sensors if it's the one that wraps around the watch leaving a cutout hole in the back.

I've got a big diamond ring but I can't wear it in my line of work. I've got the hardwood floors but no beige carpet. The only photo I've shared so far of me with the watch on is very unconventional. In lieu of gold rings and wood and carpet I present you grass and junk and a tarantula:
