I started doing it only because I've already gotten bitten by two ticks this year and have found another half dozen on me. I'm only outside a few hours a week collecting mushrooms though, I'm not lying with it pressed against my skin for ten hours straight in a hunting blind or doing anything that would cause me to sweat excessively. But yeah, at least in the Northeast it's gotten to the point where going out into the woods wearing shorts is probably far more dangerous than having unprotected sex with random people, at least as far as we can tell based on the limited tick infection statistics.
The tick problem in the Northeast USA seems to vary wildly every year. I've lived here my whole life (31 years, in the southern New Hampshire area) and I've seen tick populations fluctuate drastically from one year to the next.
A few years ago it was particularly bad: I went camping on my dad's land in northern New Hampshire one weekend and we had literally a dozen ticks crawling up our legs within five minutes of arriving. When I awoke in my tent the next morning, the outside of the tent had dozens of ticks clinging to the outside netting, trying to get in. It was impossible to walk anywhere without getting several ticks on you. None of us, including my dad who has lived here 60+ years, has seen it that bad.
In contrast, we were up at the same area a few weekends ago and we spent three days walking through the woods, camping out, and wearing shorts the whole time. The three of us had a total of 2 ticks the entire weekend.
I'm very curious to know what's influencing their numbers.
“Lyme disease is the only infection I know of where we have a safe and effective vaccine, but it’s not available to the public,” says Dr. Allen Steere, the physician who uncovered the disease:
