Cold water swimming and muscle aches
I'm working my way into colder temps without a wetsuit, and it's going reasonably well. I have a DryRobe to throw on right afterward and warm up reasonably fast. Latest swim was an hour 5 mins. in 59 degrees, and for most of it I felt fine. Usually, I start out feeling good (and loving the beauty of nature and the way the ripples reflect on tree trunks and sun beams penetrate the surface. Then I start to feel cold after maybe 15 minutes, and yet my experience tells me this is going to be temporary--which it is. Once into 20-30 minutes, I'm feeling fine again and getting into a groove. I come out, warm up, shiver some, and get on with my life.
But the last couple swims, I noticed achy muscles similar to what one would get if coming down with the flu. First time I thought maybe not a good night's sleep, maybe after effect of a flu shot (although I was three days past that). The next day I was okay, and yesterday I had a lovely swim mentioned above. Then when I got home, there were the body aches. This time, I took acetominophen, used heat, went to bed early--and today feel fine.
So my question: do you get body aches after swims like this and if so, what's a good preventive? I don't want to stop acclimating to cold. It's a pretty intense, interesting ride, and also I'm planning an English Channel relay next year (covid and weather permitting, ha!) I also entered the Lake Memphremagog Winter Games--why not try something new, right?
So I want to be fully ready to go for these events. It's already exciting to learn what I can handle--at one time, I'd be in my wetsuit by now, although I've always liked the freedom of swimming without it. (I only bought it because I wanted to swim longer into the fall and start earlier in the spring. Now? Haven't worn it for a year and a half.
Thanks for tips as I continue to acclimate.
