Have you spent lots of time out in the wilderness before? Those you describe aren’t pleasant, but you learn to accept and deal with. I’m sure the are all kinds of unpleasantness in a “civilized” lifestyle that you no longer even notice because you’re just so used to accommodating them: traffic noise, pollution, artificial light, etc.

I once spent a week hiking and camping in a rain forest. The first day I was trying to keep dry and comfortable as much as possible, and I was miserable.

The second day I realized I’m just not going to be dry, and I accepted it, and being wet didn’t bother me again the rest of the week. At the end of the day you hang you socks and clothes up near the fire and dry your boots.

Being hot and sweaty and dealing with bugs are irritating, but it’s just part of being outdoors and if you spend significant time outside doing stuff you stop noticing it and just accept it as a part of life.

Don’t let a little discomfort stop you from enjoying nature. You might even start to notice the discomforts of modern life that you’ve accepted as a part of life.
